This indoor air quality meter and data logger measures CO2 levels, CO levels, air temperature, dew point, wet bulb temperature, and humidity. It is an ideal instrument for indoor air quality (IAQ) diagnosis.

  • 4 in 1 Measures: CO, CO2, Temperature & %RH
  • In-Field Calibration with fresh air
  • Programmable CO Alarm
  • USB-out for data logging

The hand-held meter uses NDIR (non-dispersive infrared) technology for CO2 measurement to ensure reliability and long-term stability. It is useful for verifying HVAC systems' performance and air ventilation control.

CO2 + CO + RH/T Portable Meter & Data Logger

Received my Meter in Great condition - Works Great & Accurate

I received my meter in great condition. I was pleasantly surprised to find they had a 2-step QA/QC process they took in order to ensure my meter was properly calibrated and ready for use. I tested the meter for OA and CO2 and CO conditions and found it to be very accurate and fairly easy to use once I understood the procedures to access the menu's. The Operators Manual had everything I needed to understand setup. Thank you! Looking forward to buying our next meter from you.

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
