User questions & answers

Question:	Can this be rin as a stand alone with a phone app and no other devices
Answer:	Yes, you may use the AirLink as a standalone only through your phone app and just make sure you're only connecting to a 2.4 GHz network. It will not connect to a 5 GHz network. This is how I use my AirLink at home.
Question:	Does this collect historical data that i can access via the web or the app? i.e. pm10 readings graphed for the past year
Answer:	Yes, but you have to export it regularly in order to get a year's worth of data.

User questions & answers

Question:	where is this device made
Answer:	Any sounds above 120 dB will damage your hearing. 130 dB is much worse!!
Question:	Do you sell the software and hardware for data collection separately for this unit
Answer:	After posting my question here, I found an official Triplett (YouTube) video and an online instruction manual, both confirming that the SoniChek PRO-3550 is indeed tripod mountable via threaded mount located on rear of unit above battery compartment. Accordingly, I have now placed my order with Amazon seller JMAC Supply. Thanks.
Question:	where to get the 9volt adapter
Answer:	This unit is primarily a meter that measures output. Since a turntable has no measured output it would not be useful. If the turnable has a pre-amplifier , the meter can be connected to the output of the preamplifier.
Question:	Can you connect a hose for scientific experiments
Answer:	It is plastic. Not the most glamorous device - but it does provide a good adjustable meter for monitoring strength in your signal chain. I use it in my tape loop to check strength coming from multiple phono preamps.

Product description

The TIM10 CO2 Monitor lets you quickly, accurately, and inexpensively test CO2 levels around your home. Move it from room to room to test CO2 levels in your house. It can reveal if your home's heating, ventilation, and air conditioning system is operating properly. High CO2 levels indicate inadequate or closed return air ducts. Low CO2 levels indicate too much fresh air and wasted heating or cooling energy. In addition to its CO2 meter, the TIM10 has an accurate digital thermometer and relative humidity indicator. Use it to test your child's bedrooms. Low humidity in the winter can lead to nosebleeds, coughs, and sore throats. High humidity in the summer can result in mold and even structural damage. Do you own a greenhouse? Increasing CO2 makes flowering plants, vegetables, and seedlings grow bigger and faster. Working in the garage? Kerosene heaters, gasoline and diesel engines give off huge clouds of CO2 in addition to more deadly gasses. The TIM10 CO2 Monitor will warn you with an alarm before the exhaust fumes become dangerous.

• Provides accurate information about the quality of air in your home, office or greenhouse
• Continuously measures carbon dioxide, temperature and relative humidity
• Self-calibrating, no moving parts to wear out

User questions & answers

Question:	Does this unit have external sensors?if so how many,am looking for one to use specifically in a Greenhouse
Answer:	The Hub needs to be connected with an Ethernet cable, so you do require internet connectivity. The monitors themselves are wireless, and communicate with the Hub using a long range low frequency automatically once the Hub is connect to Ethernet.
Question:	Can this be used at 35 degrees F long term
Answer:	The mold risk indicator will not detect actual mold spores in the air. However, it will tell you when the conditions in a space are at risk for mold growth. This means the Wave Mini can be used to prevent mold or to proactively watch out for the chance of mold. However, once mold has started growing and is visible, it should always be removed. This can be easily done on your own. If you are unsure if what you are seeing is mold, then use a mold test kit or contact a mold professional.
Question:	Can this be used outside the US with 220v
Answer:	My answer is that in our case we are being using it to measure for intervals of 10, 20, 30 minutes with triplicate, With very good results. Never have gone for one hour. But for our validation it have perform to expected results.Hope it helps.

Understand Indoor Air Quality

Most of us spend the majority of our time indoors. The air we breathe in our homes, schools or places of work can put us at risk for health problems. Keeping a healthy indoor climate has become a bigger challenge than any of us have ever imagined. There are unlimited chemical pollutants, infectious agents, and unwanted particles that are present inside our homes affecting our health.

Have you experienced sore eyes, burning nose, throat irritation, headaches, fatigue, dizziness? Have your respiratory illnesses? Do you have heart disease, cancer and other serious long-term conditions? Have your Indoor Air Quality been checked ?

Learn and Identify the sources of your indoor pollution

There are many sources of indoor pollution that can place your family at risk. Some pollutants come from the use of appliances, smocking products, building material and furniture products, newly installed flooring, upholstery, carpet, or deteriorated asbestos, household cleaning and maintenance products like phenyl, bleaching chemicals, and even personal care products, central heating and cooling systems with humidification devices, excess of moisture, outdoor sources such as air pollution, pesticides, and harmful gases like radon.

Chronic sinusitis, trouble breathing , watery eyes

triggers of these conditions are found much closer than we think and potentially could be caused by mold, dust mites, second-hand smoke, ventilation, pet dander, air fresheners, personal care products we use. Take control of your Indoor Air Quality in every room. Very often we pay attention to what we eat, but completely ignore what we breath.

As a scientific air quality detection device, it combines multiple air sensors with a built-in fan to allow real-time monitoring of indoor air pollution and air quality

Primary Causes of Indoor Air Problems:

In order to maintain a healthy indoor climate, we need to identify the substances that are already present in our households and plummeting our health. We know that inadequate ventilation increase indoor pollutants by not bringing the outdoor air inside that can dilute the emissions from indoor substances. Moreover, it can’t carry indoor air pollutants outside the house, resulting in high temperature and humidity levels. The sources of these pollutants are:

• Appliances that use fuel
• Tobacco products
• Building materials and furnishing products such as pressed wood products, newly installed flooring, upholstery, carpet, or deteriorated asbestos
• Household cleaning and maintenance products like phenyl, bleaching chemicals, and even personal care products
• Central heating and cooling systems with humidification devices
• Excess of moisture
• Outdoor sources such as air pollution, pesticides, and harmful gases like radon

Measures to Maintain Healthy Indoor Climate:

Under the Environmental Justice movement, EPA has defined and addressed various measures that can be taken to keep the indoor air quality ideal. As long as children, elderly, and other people with severe respiratory diseases are inside a healthy indoor climate, they can live in comfort.

Hence, all households needs need to take care of their ventilation systems to reduce the health risks of bad air quality. You can either install a new and improved ventilation system or consider using air quality monitors. While some people choose the ventilation system over monitors, it is our duty to suggest using monitors as well. Just achieving an ideal healthy indoor climate is not enough; we need to manage it afterward.
