Product Specification

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.

System Components

Sensor: The sensor element employs a patent‐pending, chemi‐resistive ceramic technology, which provides accurate
and reliable hydrogen detection.
