MH-Z14 NDIR Infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature sensor can do temperature compensation; and it has digital output and analog voltage output. This infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, Precision optical circuit design and superior circuit design.


MH-Z14 NDIR Infrared gas module is applied in the HVAC, indoor air quality monitoring, industrial process,
safety and protection monitoring, agricultural and animal husbandry production process monitoring.
