-
It is a solid state direct Hydrogen gas measurement sensor.
-
It uses a unique galvanic electrochemical sensor based on proton conducting solid electrolyte and a novel solid reference electrode (Proprietary Indian Patent NO. 252998 w.e.f. 14/06/2007).
-
State of art technology sensor.
-
Intelligent to Hydrogen, therefore selective and specific, hence no interference from other gases.
-
Long life and minimal maintenance.
-
No on-board heaters are required. Very low power.
-
Tolerates exposure to high concentration Hydrogen gas where other sensors can fail
