SPD235PLUS CO and CO2 Concentration Detector

Features:

Simultaneously measure the concentrations of CO and CO2 in the air, and can serve as a monitoring controller to control relays and connect external ventilation equipment for ventilation when the gas concentration exceeds the

standard. SPD235plus is designed to enhance industrial and environmental applications, using dual wavelength non dispersive infrared CO2 sensors and electrochemical CO sensors. It has high accuracy and can display both gas measurements simultaneously, with ultra-low power consumption and long standby time.
