Carbon Dioxide CO2/Temp/%RH Meter
(Model No.: 512)
The CENTER 512 Carbon Dioxide (CO2) meter is a CO2 gas detector with data loggering function, which could measure the indoor air quality of CO2 concentration level, air humidity and air temperature.
Data can be stored in the meter or directly saved on a computer through PC interface. Recorded data can be further processed by PC computer. The CENTER 512 CO2 meter could be used as the CO2 data logger for the air quality measurement in all workspace, office, hospital, school, station or home.
