Basic CO2 Sensor and Transmitter
Real time monitoring of CO2 concentration in indoor air. NDIR infrared CO2 sensor, self calibration function, greater than 10 year service life. Temperature and humidity detection optional, temperature and humidity integrated digital sensors to provide full range, high-precision detection. Wall mounted, sensor outside in the probe, the measurement accuracy is higher. Backlit LCD displays CO2 measurements or CO2+ temperature and humidity measurements. Provides 1 or 3 way 0~10VDC/, 4~20mA, or 0~5VDC analog output. The Modbus RS485 communication interface makes getting measurements simpler. Light structure, easy installation. CE authentication
