11 best quest breathalyzers

Quest breathalyzers are portable devices designed for measuring blood alcohol content (BAC) by analyzing a person's breath. These devices are commonly used in various settings, including personal use, law enforcement, and workplace safety. Here is some information about Quest breathalyzers:

  1. Functionality: Quest breathalyzers work based on the principle that alcohol in the bloodstream is detectable in a person's breath. When a person exhales into the device, it measures the concentration of alcohol vapor in their breath and calculates their estimated BAC.

  2. Personal Use: Quest breathalyzers are often used by individuals who want to monitor their alcohol consumption and make informed decisions about driving or other activities. They provide a quick and convenient way to estimate BAC levels.

  3. Law Enforcement: Law enforcement agencies may use more advanced breathalyzer models, including those produced by Quest, to determine if a driver is under the influence of alcohol. These devices are typically more accurate and reliable than personal-use models.

  4. Workplace Safety: Some workplaces, particularly those with safety-sensitive positions, use breathalyzer testing as part of their alcohol testing policies to ensure a safe working environment. Quest breathalyzers can be used in such settings to screen employees for alcohol impairment.

  5. Accuracy: The accuracy of Quest breathalyzers can vary depending on the specific model and technology used. Law enforcement-grade devices tend to be more precise and are often subject to strict calibration and maintenance procedures.

  6. Portability: Many Quest breathalyzer models are compact and portable, making them suitable for on-the-go use. They can easily fit into a pocket or purse, allowing individuals to carry them for testing whenever necessary.

  7. Display and Results: Quest breathalyzers typically have digital displays that provide the user with their BAC reading.Results are usually displayed in terms of a percentage, indicating the alcohol concentration in the bloodstream.

  8. Calibration: For accurate results, Quest breathalyzers require periodic calibration to ensure that they are functioning correctly. Some models may come with calibration kits or services.

  9. Legal Implications: It's important to note that the legal BAC limit for driving varies by jurisdiction, and driving with a BAC above the legal limit can result in severe legal consequences, including fines and license suspension.

  10. Health Considerations: Breathalyzers are generally considered safe for use, but they are not intended to diagnose or treat any medical conditions. People with specific medical conditions or taking certain medications may experience variations in breathalyzer results.

Quest breathalyzers, like other breathalyzer devices, serve as valuable tools for monitoring alcohol consumption and promoting safety. Users should be aware of the device's limitations and should always make responsible decisions regarding alcohol consumption and activities such as driving.

  • Psycho

    For all the slasher pictures that have ripped off Psycho (and particularly its classic set piece, the "shower scene"), nothing has ever matched the impact of the real thing. More than just a first-rate shocker full of thrills and suspense, Psycho is also an engrossing character study in which director Alfred Hitchcock skillfully seduces you into identifying with the main characters--then pulls the rug (or the bathmat) out from under you. Anthony Perkins is unforgettable as Norman Bates, the mama's boy proprietor of the Bates Motel; and so is Janet Leigh as Marion Crane, who makes an impulsive decision and becomes a fugitive from the law, hiding out at Norman's roadside inn for one fateful night. --Jim Emerson



    Rear Window

    Like the Greenwich Village courtyard view from its titular portal, Alfred Hitchcock's classic Rear Window is both confined and multileveled: both its story and visual perspective are dictated by its protagonist's imprisonment in his apartment, convalescing in a wheelchair, from which both he and the audience observe the lives of his neighbors. Cheerful voyeurism, as well as the behavior glimpsed among the various tenants, affords a droll comic atmosphere that gradually darkens when he sees clues to what may be a murder.

    Photographer L.B. "Jeff" Jeffries (James Stewart) is, in fact, a voyeur by trade, a professional photographer sidelined by an accident while on assignment. His immersion in the human drama (and comedy) visible from his window is a by-product of boredom, underlined by the disapproval of his girlfriend, Lisa (Grace Kelly), and a wisecracking visiting nurse (Thelma Ritter). Yet when the invalid wife of Lars Thorwald (Raymond Burr) disappears, Jeff enlists the two women to help him to determine whether she's really left town, as Thorwald insists, or been murdered.

    Hitchcock scholar Donald Spoto convincingly argues that the crime at the center of this mystery is the MacGuffin--a mere pretext--in a film that's more interested in the implications of Jeff's sentinel perspective. We actually learn more about the lives of the other neighbors (given generic names by Jeff, even as he's drawn into their lives) he, and we, watch undetected than we do the putative murderer and his victim. Jeff's evident fear of intimacy and commitment with the elegant, adoring Lisa provides the other vital thread to the script, one woven not only into the couple's own relationship, but reflected and even commented upon through the various neighbors' lives.

    At minimum, Hitchcock's skill at making us accomplices to Jeff's spying, coupled with an ingenious escalation of suspense as the teasingly vague evidence coalesces into ominous proof, deliver a superb thriller spiked with droll humor, right up to its nail-biting, nightmarish climax. At deeper levels, however, Rear Window plumbs issues of moral responsibility and emotional honesty, while offering further proof (were any needed) of the director's brilliance as a visual storyteller. --Sam Sutherland

    North By Northwest

    A strong candidate for the most sheerly entertaining and enjoyable movie ever made by a Hollywood studio (with Citizen Kane, Only Angels Have Wings and Trouble in Paradise running neck and neck). Positioned between the much heavier and more profoundly disturbing Vertigo (1958) and the stark horror of Psycho (1960), North by Northwest (1959) is Alfred Hitchcock at his most effervescent in a romantic comedy-thriller that also features one of the definitive Cary Grant performances. Which is not to say that this is just "Hitchcock Lite"; seminal Hitchcock critic Robin Wood (in his book Hitchcock's Films Revisited) makes an airtight case for this glossy MGM production as one of The Master's "unbroken series of masterpieces from Vertigo to Marnie." It's a classic Hitchcock Wrong Man scenario: Grant is Roger O. Thornhill (initials ROT), an advertising executive who is mistaken by enemy spies for a U.S. undercover agent named George Kaplan. Convinced these sinister fellows (James Mason as the boss, and Martin Landau as his henchman) are trying to kill him, Roger flees and meets a sexy Stranger on a Train (Eva Marie Saint), with whom he engages in one of the longest, most convolutedly choreographed kisses in screen history. And, of course, there are the famous set pieces: the stabbing at the United Nations, the crop-duster plane attack in the cornfield (where a pedestrian has no place to hide), and the cliffhanger finale atop the stone faces of Mount Rushmore. Plus a sparkling Ernest Lehman script and that pulse-quickening Bernard Herrmann score. What more could a moviegoer possibly desire?--Jim Emerson

    Vertigo

    Although it wasn't a box-office success when originally released in 1958, Vertigo has since taken its deserved place as Alfred Hitchcock's greatest, most spellbinding, most deeply personal achievement. In fact, it consistently ranks among the top 10 movies ever made in the once-a-decade Sight & Sound international critics poll, placing at number 4 in the 1992 survey. (Universal Pictures' spectacularly gorgeous 1996 restoration and rerelease of this 1958 Paramount production was a tremendous success with the public, too.) James Stewart plays a retired police detective who is hired by an old friend to follow his wife (a superb Kim Novak, in what becomes a double role), whom he suspects of being possessed by the spirit of a dead madwoman. The detective and the disturbed woman fall ("fall" is indeed the operative word) in love and...well, to give away any more of the story would be criminal. Shot around San Francisco (the Golden Gate Bridge and the Palace of the Legion of Honor are significant locations) and elsewhere in Northern California (the redwoods, Mission San Juan Batista) in rapturous Technicolor, Vertigo is as lovely as it is haunting. --Jim Emerson



    Birds

    Vacationing in northern California, Alfred Hitchcock was struck by a story in a Santa Cruz newspaper: "Seabird Invasion Hits Coastal Homes." From this peculiar incident, and his memory of a short story by Daphne du Maurier, the master of suspense created one of his strangest and most terrifying films. The Birds follows a chic blonde, Melanie Daniels (Tippi Hedren), as she travels to the coastal town of Bodega Bay to hook up with a rugged fellow (Rod Taylor) she's only just met. Before long the town is attacked by marauding birds, and Hitchcock's skill at staging action is brought to the fore. Beyond the superb effects, however, The Birds is also one of Hitchcock's most psychologically complicated scenarios, a tense study of violence, loneliness, and complacency. What really gets under your skin are not the bird skirmishes but the anxiety and the eerie quiet between attacks. The director elevated an unknown model, Tippi Hedren (mother of Melanie Griffith), to being his latest cool, blond leading lady, an experience that was not always easy on the much-pecked Ms. Hedren. Still, she returned for the next Hitchcock picture, the underrated Marnie. Treated with scant attention by serious critics in 1963, The Birds has grown into a classic and--despite the sci-fi trappings--one of Hitchcock's most serious films. --Robert Horton

    Quest Nutrition's mission is to revolutionize food and make clean eating fun! Quest Bars were created from a simple idea: Food should taste as good as it is good for you.

    QUEST NUTRITION

    User questions & answers

    Question: How many chips for the price
    Answer: The title says: "Quest Tortilla Style Chips - Chili Lime - 30 Count" It is correct...30
    Question: Are the chips still coming smashed in the box
    Answer: The order I received in July was smashed - very disappointed because these chips are good. The orders i've done where there is just 1 flavor of chip instead of the combination have been fine. They seem to be packed more upright and not just thrown in the box. Hope that helps.
    Question: Are the potatoe chips the new revitalized ones
    Answer: I’m not sure what you mean by revitalized. They are high nutrition/protein and if you need something crunchy these fit the bill.
    Question: Have you fixed that packaging issue? Seems to be a theme in most reivews
    Answer: I’m not sure if this question was meant for me or the seller... the chips did come shoved in a big box. Some bags were flattened, others weren’t. I haven’t had a bag were they were COMPLETELY smashed into crumb, but a few with a bunch of broken pieces.
