Extech CO230 -
Extech Instruments Corporation
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).

SenseAir CO2 -
Askey Dataloggers
aSENSE is an advanced transmitter for installation in the climate zone. It measures both CO2 concentration and temperature. The data is transmitted to a BMS system or controller and can be configured with UIP Software. Detected values are transformed into two analogue output signals that can be transmitted to a system master or DDC. aSENSE is available both with and without LCD display for FIXED installation in the climate zone as well as in the ventilation duct.
