High sensitivity NTC
NTC thermistor compensation
Fast response time
4.26 μm narrow bandpass filter
The STG-HA11-F4.26 is an infrared thermopile gas sensor developed by Senba Sensing. The STG-HA11-F4.26 measures gas concentration by detecting changes in thermopile resistance and is housed in a TO-46 metal package with a 4.26 µm narrow bandpass filter for gas sensitivity. The STG-HA11-F4.26 offers high sensitivity and fast response performance. The STG-HA11-F4.26 is used in indoor air monitoring, ventilation systems, in-vehicle air purification, and industrial gas measurement applications.
