Product Review: Extech CO200 Desktop Indoor Air Quality CO2 Monitor

Why Measure Indoor CO2?

Indoor Air Quality (often shortened to IAQ) refers to the air quality within enclosed or semi-enclosed buildings. One of the most important and quietly sinister indoor pollutants is CO₂.

Indoor CO₂ at high levels will cause people to feel drowsy and sluggish, eventually resulting in nagging headaches – which is not ideal if you're a professional concerned about workers' productivity.

Within a home, CO₂ levels indicate whether air ventilation is healthy for the occupants. Poor ventilation means lower metabolic activity, poorer quality of life, and may ultimately contribute to health conditions.

We recommend owning and regularly using an inexpensive yet effective C02 Monitor as a simple, practical, and precise way to prevent this pollutant's negative impacts on occupants in indoor environments.

In summary, Instrument Choice scientists reckon the Extech CO200 Desktop Indoor Air Quality CO2 Monitor is more than capable of providing years of precise indoor air quality measurements in the home or workplace. At any time, you can immediately assess whether CO₂ levels are ridiculously healthy, OK, or downright ugly!

Now here's a little more technical detail…

Extech CO200 Desktop Indoor Air Quality CO2 Monitor – Features and Specifications 

• Accurately checks for and displays the current indoor Carbon Dioxide (CO₂) concentration.
• An accurate and maintenance-free NDIR (non-dispersive infrared) CO₂ sensor.
• The measured indoor air quality is displayed in ppm with easy to interpret indications. These are; Good (380 to 420ppm), Normal (<1000ppm) and Poor (>1000ppm).
• The CO200 has both visible and audible warning alarms when CO₂ levels exceed safe limits.
• The CO200 has a relay output for connection to an external indicating or controlling device. When CO₂ readings go over the upper limit, the relay closes. The relay will open again when CO2 readings fall below the lower limit. The relay output port requires a 2.5mm STEREO phone jack plug. The relay is 1A 30VDC/0.5A 125VAC.
• Users can recall Max/Min CO₂ values at the touch of a button.
• Operators can perform either; automatic baseline calibration (minimum CO₂ level over 7.5 days) or manual calibration in the fresh air.
• The screen displays the year, month, date, and time.
• The CO200 comes complete with a universal A.C. adaptor, so you don't need to worry about changing the batteries.
