Question: Can this be left out specifically as an alarm in a camper? Typical home alarms don't work well in small spaces cause they go off too easily
Answer: Yes, water does tend to get underneath of it so I take it off most of the time but sometimes I use the opportunity to take off the protector and wash it as well.
Question: I want a device to test my home gas fireplaces at start of season. Is this want I need
Answer: If I'm understanding your question correctly, yes. You can print anything as long as you have a printer.
Question: What's the difference between this and the more expensive versions up to
Answer: Nikki, Derwent Lightfast are oil-based colored pencils. They are NOT used with water. If you are looking for watercolor media, you might want to try Derwent Inktense Pencils or Intense Blocks. If you're concerned with colors fading over time, most of the Derwent products have a good lightfast rating. Hope this helps.
Question: Can anyone please confirm if it gives readings below 35? ie 1, 8 etc? (important) Manufacture/user have different statements... any owners chime in
Answer: Go to Derwent’s website. They have a complete color chart that shows which colors are in which size sets. I got there by googling “Derwent Lightfast Colored Pencil Reviews”. As you know, it’s a UK company, but they have a US website. BTW, the largest set available in the US right now is 72 pencils. They apparently have a set of 100 that is available only in the UK but is coming here in the hopefully near future. I’ve been told that this very consumer-responsive company has been kind enough to provide a set of the new 28 colors for those of us who have the other 72 already. Also, if you sign up for Dick Blick’s emails, they have promised an alert as soon as the new sets are available. They won’t deluge you with a million emails a week either. Hope this helps.
Question: Is this overkill if i a Avg joe who travels a lot? I'm not a pro user, just need a good portable loud alarm for my family
Answer: Yes. Go to the Derwent website. There is a UK site and an American site, I ordered the newest individual colors from the UK because the individual pencils were nit available in the IS at the time.

Question: Can you get a case or does it come with one
Answer: Dear Talia,Good day and thank you for your recent inquiry.Testo 0632 3173 comes with Certificate of Conformity.This unit usually does not get any type of Nist calibration because Nist is usually more expensive than the unit itself.It is only supposed to be used for ambient not any type of combustion forms. The manufacturer does not recommend full calibration as this unit is not meant for that. It is meant for ambient measurements only. The normal Nist Calibration is about $200.00."For more detailed information please contact the manufacturer's technical support at (800)227-0729.If you have any further questions please don't hesitate to contact us. It would be a pleasure to help in any way we can.Sincerely,Yana-- Your Mega Depot® Customer Service Team
Question: can this meter be used in automotive applications and if so is it accurate enough to measure co in automotive cooling system
Answer: Hello, yes, this item includes earphone jack, and earbuds for loud environments.
Question: Is it accurate enough to mesure outdoor CO levels (<10 ppm
Answer: The Testo is a personal monitor which can be used to detect CO levels down to 1ppm. It is not meant to be used as a CO Alarm that is to be installed in one's home. The Kidde CO alarm, on the other hand, does meet UL standards to be used as an installed alarm. However, UL standards require CO alarms to sound at much high levels of CO than the personal Testo CO detector would. The Kidde will only display CO levels of 30ppm or greater.

    User questions & answers

    Question: How loud is the alarm
    Answer: Yes it came with ac cable.
    Question: can one tell how much CO one is exhaling with this
    Answer: It doesn't say on the boxes I would say no.
    Question: Can this detect pm
    Answer: I bought a 24 count. Anything smaller wasn’t economical. Now I only buy the 40 count.
    Question: The description states it detects above zero CO ppm. What is the lowest level this can detect
    Answer: I like a strong blend. I would not consider this to be very strong at all. It has a bit of a chalky taste to it as well. It's not my first choice.
