Portable Hydrogen Leak Detector

21 Senses Inc.

Patented solid-state electrochemical sensor with novel reference electrode.
Detects hydrogen ≥ 1 ppm with T90 ≤ 2.5 s.
Withstands 100 % H₂ exposure.
Detects in multiple background gases
P65 ABS handheld enclosure; rugged for indoor/outdoor use.

The Portable Hydrogen Leak Detector is a highly sensitive and fast-response portable device designed for detecting hydrogen leaks with exceptional precision. It uses patented Solid State Electrochemical Sensor Technology and a Novel Reference Electrode to measure hydrogen partial pressure directly, ensuring specificity and selectivity in various gas backgrounds. The device can detect leaks as low as 1 ppm and has an ultra-fast response time of 0.5 to 2.5 seconds, enabling early exposure detection. It is durable, certified for international standards, and suitable for multiple industries and applications. The device features a backlit graphical 4-line LCD display, audio and visual alarms, and is capable of operating in a wide range of temperatures and humidity levels. It is ideal for use in industries such as Oil & Gas, Power Generation, Petrochemicals, Pharmaceuticals, and more, and is designed for both indoor and outdoor applications.

Use Cases

Electrolysers (PEM, Alkaline, SOEC and other burgeoning technologies)
Fuel Cells (PEM and SOFC)
Hydrogen Supply Chain (Transport Pipelines, Containers, Storage Sites, Tankers, and Fuelling Pumps)
