SenseH2 Hydrogen Sensor (H2 Sensor) Overview
Designed for hydrogen monitoring, this ceramic sensor exhibits a highly sensitive, selective, and rapid response to the presence of hydrogen in ambient air. It reliably measures H2 concentrations over a wide range of temperature and humidity variation and provides a repeatable response, even in the presence of other combustible gases. Additionally, the NTM SenseH2® hydrogen sensor is immune to signal saturation upon continuous exposure to low levels of hydrogen, and recovers rapidly and completely upon hydrogen removal.

SenseH2 Hydrogen Sensor (H2 Sensor) System Components
Sensor: The sensor element employs a patent-pending, chemi-resistive ceramic technology, which provides accurate
and reliable hydrogen detection.
Electronics package: The sensor provides a simple interface with a ratio-metric voltage output (1 to 4.5 VDC; 500mV increments), calibrated to detect up to 4% H2 in air (100% of the LFL). Diagnostic states (<1V, >4.5V) are provided to indicate error conditions. Microprocessor - based heater control ensures stable operation, in temperatures ranging from -20 to 80°C. The compact, rugged design and waterproof connector enable use of the NTM SenseH2 hydrogen sensor in a range of application conditions. Mating connectors can be purchased separately for ease of installation.
