With up to 24 hours battery life and easy to use with gloves on, the High Accuracy portable carbon dioxide meter works perfectly for precision monitoring of CO2, temperature, and relative humidity in any location and it works great as a personal safety alarm unit in hazardous environments.

  • CO2, Temperature, Humidity
  • Includes International Power Supply
  • Save Money - Calibrate Outdoors
  • High Accuracy

The large LCD readout gives a quick overview of the current carbon dioxide level, temperature, and relative humidity, and the 80 dB audible alarm calls for prompt attention when the short-term exposure safety limit is exceeded.

This air quality CO2 meter data logger calculates statistical weighted averages of TWA (8 hour time weighted average) and STEL(15 minute short term exposure limit).

Optional Data Logger Kit

The optional data logger kit for Windows PC is perfect for students, scientists, researchers, or anyone who needs to record CO2 levels over time. Each reading (user-selected frequency) includes a date/time stamp for accurate analysis. Use the kit to record CO2 and temperature levels for an hour, a day, or even a month. Data can be viewed on screen or saved to an ASCII text data file that easily imports into a spreadsheet.

    Easy to Use

    I am very sensitive to elevated CO2 levels and bought this to evaluate my home and other spaces. Turned it on and it told me what I wanted to know with no learning curve! Awesome tool!
