Features

Quick start up & response

Start up time in 1 sec. after power-on and response speed within 3 sec. have been achieved. In case a hydrogen leak occures during parking, there is a possibility of explosion when the battery is turned on. To avoid this danger, hydrogen leak must be detected within 3 sec. after ignition switch gets powered on. Nissha’s hydrogen sensors start response within 3 sec. and satisfy the requirements from automobile industries.

Start up response of Hydrogen sensor

High Hydrogen Selectivity

We provide the sensors that excel in gas sensitivity and no occurance of mis-detecting other gases.
Our hydrogen sensors show stable performance, and are not influenced by other gases (ethanol, methane, etc.) that could be generated in an operating environment.

Gas sensitivity

High durability that satisfies the strict in-vehicle requirements

Our sensors realize the stability that clears various in-vehicle standards.

Continuous powered operation
long term stability in normal environment
Unpowered operation

Our sensors provide the safety and relief
for fuel cell applications

Nissha’s catalytic combustion type hydrogen sensors are the world's first sensors, which were installed in actual fuel cell vehicles for the detection of hydrogen gas.Hydrogen technology contributes to the safety and prevention of global warming.

What is Hydrogen?

Catalytic combustion type sensors with high durability and quick response speed

Our hydrogen sensors are catalytic combustion type.

General catalytic combustion type sensors has a housing that covers heater with inorganic material (career), which contains catalytic that detects hydrogen. We developed a catalytic combustion type hydrogen sensor with a unique design, which is different from general sensors.

Our sensors achieved "quick start-up, response speed & high durability, against siloxane poisoning, ".
