The hydrogen gas detector is mainly used to detect the concentration of hydrogen (H2) in the air. This gas detector is used for personal protection in hazardous gas environments. It is also found in industrial environments, battery storage centers, and hydrogen fuel cell facilities. Hydrogen is an important alternative energy source, but it can become dangerous if it leaks and builds up indoors.

Pros

Small and low-cost gas detectors are available for H2 gas safety.

Easy to use hydrogen electrochemical cells.

Many H2 detector models are available for less than $399.

How Is Hydrogen (H2) Gas Detected?

Hydrogen is detected using a measuring instrument known as a hydrogen gas detector. These devices are specific to hydrogen gas. Hydrogen gas detectors are composed of electronics and an H2 sensor.

The gas sensor converts the detected hydrogen gas concentration to an electronic signal for analysis by the onboard microprocessor. From there, the processor outputs the reading to the display. If the measured amount of H2 exceeds the pre-set values, alarms will be triggered to warn the user. Other functions, such as instructing a relay to switch on a fan or ventilation system, are also common.

What Is a Portable Hydrogen Gas Detector?

A portable hydrogen gas detector is an instrument used to analyze the concentration of hydrogen in the air. These small gas detectors have a long-lasting battery, large screen that displays the hydrogen levels, and a belt clip to connect to clothing. The devices also have LED, vibration, and buzzer alarms.

A hydrogen gas detector is sometimes called an H2 monitor, a hydrogen sniffer, a hydrogen analyzer, or hydrogen gas tester. These names all refer to a hydrogen gas detector.

What Does a Hydrogen Detector Measure?

A hydrogen gas detector senses hydrogen (H2) in the air and displays the levels in parts per million (ppm) concentration.

While most hydrogen gas detectors detect low ppm levels (0 - 1000 ppm), others are designed to measure higher level concentrations in %LEL.

What Are the Different Types of Hydrogen Gas Detectors?

Hydrogen Gas Detector for Personal Protection

The majority of hydrogen gas detectors are portable. These small, battery-powered units contain a hydrogen sensor and can be clipped to your clothes. These detectors provide continuous personal protection with LED, buzzer, and vibration alarms.

Hydrogen Gas Monitor for Stationary Fixed Wall

Fixed wall-mounted units provide continuous H2 protection. These devices are perfect for indoor situations, such as a battery room or power generator area. If the H2 levels rise above a pre-set threshold, the unit will alarm and can automatically trigger the ventilation system.
