CO220 Datasheet, PDF (1/1 Pages) Extech Instruments Corporation. – Desktop Indoor Air Quality CO2 Monitor

CO220 Desktop Indoor
Air Quality CO₂ Monitor
Measures Carbon Dioxide (CO₂),
Air Temperature and Humidity, plus
calculates Dew Point and Wet Bulb.
User settable high/low alarm function
is perfect for monitoring air quality
and insuring proper air ventilation
in conference rooms, schools,
greenhouses, factories, hotels,
hospitals and anywhere that high levels
of carbon dioxide are generated.
Features
• Displays Carbon Dioxide (CO₂) concentrations
• Maintenance free NDIR (non-dispersive infrared)
CO₂ sensor
• Carbon Dioxide reading displayed in ppm with six facial
icons indicating indoor quality levels (illustrated below)
• Audible CO₂ warning alarm when concentration level
exceeds high or low user set point
• Displays Year, Month, Day, and Time
• Min/Max CO₂ value recall function
• Calculates Dew Point and Wet Bulb values
• Calculates statistical weighted averages of TWA (8 hour
Time Weighted Average) and STEL (15 minute Short
Term Exposure Limit)
• lps% (Liters per second per person) and cfm/p (cubic
feet per minute per person)
• Automatic Baseline Calibration function
• Manually store/recall 99 readings
• Complete with AC adaptor
