Description
Features
? Real-time monitoring carbon dioxide (CO2) measurements during 0ppm to 20,000ppm range
? Optional real-time monitoring temperature from -20℃ to 60℃ and relative humidity from 0 to 100%RH
? Non-dispersive infrared (NDIR) CO2 sensor with self calibration, 15 years lifetime
? The 3-LED indicator lights indicate three CO2 measured ranges
? LED lights brightness adjustable
? Provide 1X0~10VDC output for alternative linear
CO2 measurement and PID control output
? Provide 1X On/Off dry contact output to control alternative a ventilator and a CO2 generator
? An internal data logger is used to record CO2 measurements as well as optional temperature and RH% measurements.
? With super large capability memorizer, it can save data of up to 115 days
? Provide the software to preset the sampling time, read and record CO2/temperature&RH levels on PC
? Post the data from the internal memorizer by any USB disk, and copy the data to a PC
