- Choice of desktop setup, or wall mount attachment

- Stable non-dispersive infrared (ndIR) sensor for CO2 detection
Product Description
The Supco IAQ50 indoor air quality monitor is a wall-mounted or desktop device that simultaneously displays carbon dioxide (CO2/ppm) concentration, temperature (degrees C or F), and % relative humidity, has an internal non-dispersive infrared (ndIR) sensor, and a programmable, audible, and visible CO2 concentration alarm. An indoor air quality (IAQ) monitor is used for diagnostics, to identify CO2 concentration levels in sick building syndrome, and for continuous monitoring of residential, and professional environments, such as warehouses, restaurants, garages, and greenhouses.
This IAQ monitor has an LCD display to simultaneously show CO2 concentration, air temperature, and % relative humidity. The device warms up in 30 seconds. Its time-weighted average (TWA) is 8 hours, and its short-term exposure limit (STEL) is 15 minutes weighted average. The device emits an audible beep of 80 decibels that can be manually stopped, and the beep automatically stops when the CO2 reading falls below the lower limit. It is factory-calibrated at 400ppm CO2 concentration for automatic baseline calibration (ABC), and can be manually CO2-calibrated. It has a long time drift compensation, and minimum/maximum average recall. The non-condensing operational range is +32 to 122 degrees F (0 to 50 degrees C), and it has a -4 to 140 degrees F (-20 to 60 degrees C), non-condensing storage range. An RS-232 port provides a computer connection. The IAQ50 works with an included 12V adapter, and comes with a 2-year, limited warranty.

An indoor air quality (IAQ) monitor is used for continuous monitoring of various parameters by professionals and hobbyists in the home health, aquaculture, agriculture, automotive, and food and beverage industries. Common parameters include relative % humidity, temperature, and carbon dioxide (CO2) concentration levels. An IAQ monitor can be handheld, desktop, and wall mount, or a combination of these types.

Very sensitive
By David
I bought this because I installed an unvented gas heater in my basement to heat my office area.CO2 meter arrived a few days before plumber arrived to hook up heater, so I plugged it in to get an idea of baseline CO2 levels without this new heater. Of course, humans exhale carbon dioxide. Meter is about 5 ft from my body, at 9 o'clock when I am facing 12 o'clock at my desk. When I sat down, meter read 451 parts per million. After an hour or so it read 568 ppm, just from me breathing. When two plumbers were here to hook up heater to gas line, 3 of us were within 10 feet of the meter. Reading at start was 465. Reading with 3 of us exhaling for an hour was 760.Don't know how accurate it is, but it sure is sensitive. Easy to operate. Alarm can be set at different CO2 levels. A little pricy compared to carbon monoxide meters, but well worth the money with an unvented gas heater 6 ft behind me. BTW, carbon monoxide (CO) meter is at 3 o'clock when I am facing 12 o'clock. CO2 to my left and CO to the right. Can't be too careful with unvented combustion heaters, IMO.

By Elac
This is a great CO2 monitor.Very accurate and sensitive to CO2 changes.The alarm is quite audible.
2 of 2 people found the following review helpful.Accurate and sensitive CO2 monitoring
By P. Chevrette
When I've received this item, the first thing I've done is to take out the CO2 measure outside. The reading was 397 PPM, wich is accurate enough, since it varies mostly from 350 to 450 CO2 year round. Regarding inside readings, again, I think it's very accurate and sensitive. When the HRV is fully founctioning (no defreezing cycle), the readings inside varies from 600 to 700 ppm, wich is what we should expect. When it's very cold outside, the HRV is often on the defreezing cycle, so it takes less fresh air from outside. The readings are then near 450 ppm when we come from work, and approximately 1000 ppm next morning. So again, that's consequent with the fresh air ventilation rate. At Christmas, we were 40 people at home and it was cold. At the end of the night, the CO2 reading was at 4000 ppm (!). So I took it outside to see. Within few seconds, the reading was at 450 ppm. It's very sensitive.That being said, I can't tell that relative humidity monitoring (and so dew point measurement) is accurate. I have some reliable HR sensors in the house and they all tell the same with 1 to 3% diffences. This monitor is 6% below all of them. That's too much of a difference. If you are looking to buy a cheap and reliable CO2 sensor, I think that it is a very good buy. If you're looking for a relative humidity sensor, there is more reliable and cheaper options out there.
