CO200 is a Desktop Indoor Air Quality CO2 Monitor. Measurement ranges are 0 to 9,999 ppm (CO2), 14 to 140°F (-10 to 60°C) for Air Temperature and 0.1 to 99.9% for Relative Humidity. It features Minimum/Maximum CO2 value recall, Year/Month/Date/Time display, and an Automatic Baseline Calibration (minimum CO2 level over 7.5 days) or manual calibration in fresh air. Comes with AC adapter and user manual.

CO210 is a Desktop Indoor Air Quality CO2 Monitor/Datalogger. Measurement ranges are 0 to 9,999 ppm (CO2), 14 to 140°F (-10 to 60°C) for Air Temperature and 0.1 to 99.9% for Relative Humidity. It features Minimum/Maximum CO2 value recall, Year/Month/Date/Time display, and an Automatic Baseline Calibration (minimum CO2 level over 7.5 days) or manual calibration in fresh air. Comes with AC adapter and user manual.

The CO220 Air quality CO2 monitor measures carbon dioxide, air temperature and humidity. The CO220 also calculates dew point and wet bulb. Use in conference rooms, schools, greenhouses, factories, hotels, hospitals and anywhere that high levels of carbon dioxide are generated. Calculates statistical weighted averages of TWA (8 hour Time Weighted Average) and STEL (15 minute Short Term Exposure Limit). Maintenance free NDIR (non-dispersive infrared) CO2 sensor. Manually store/recall 99 readings. Complete with AC adaptor.

The CO230 measures Carbon Dioxide (CO2), Air Temperature and Humidity, plus calculates Dew Point and Wet Bulb. Features Automatic Baseline Calibration (ABC) with disable for use in areas with continuously elevated CO2 levels. Its alarm function with user settable high/low CO2 level is perfect for monitoring air quality and ensuring proper air ventilation in conference rooms, schools, greenhouses, factories, hotels, hospitals and anywhere that high levels of carbon dioxide are generated. The CO230 also calculates Dew Point and Wet Bulb values, Min/Max CO2 value recall function, statistical weighted averages of TWA (8 hour Time Weighted Average) and STEL (15 minute Short Term Exposure Limit), Alarm relay output for ventilation control and wall mount. Complete with Universal AC adaptor and multiple plug types (US, EU, UK, AUS).

The AN320 is a Large Vane CFM/CMM Anemometer/Psychrometer plus CO2. This meter measures Air Velocity, Air Flow, Relative Humidity, Wet Bulb, Dew Point and Carbon Dioxide. Extech’s Large Vane Thermo-Anemometer series allows for more precise readings on larger size ducts. Min/Max, Data Hold, and Auto power off functions. Complete with 4 AAA batteries and hard carrying case.

The CO50 is a desktop CO Monitor which measures and displays carbon monoxide concentration, air temperature and humidity simultaneously. The CO50 features visibly bright LED lights which indicate active monitoring (green) or a surpassed CO alarm threshold (red). The meter also features an extra loud audible beeper alarm, electrochemical CO sensor, record/recall Max reading for CO concentration and CO calibration function in fresh air. Product is complete with Universal AC adapter (100V-240V) with multiple plug types (US, EU, UK, AUS) and a user's manual.
