Hydrogen Leak Detector

Extrima®

Ex-Certified Hydrogen Leak Detector

The portable Extrima Leak Detector is the ultimate intrinsically safe instrument for leak detection in the toughest environments, including hazardous locations such as Zone 0 (corresponding to Division 1).

The Extrima allows you to quickly find leaks on a wide range of industrial applications such as aircraft and hydrogen cooled generators. With the Extrima the aviation industry has a safe, accurate and yet simple solution for leak testing of complete fuel systems, both in production and maintenance situations. Thanks to its high sensitivity, the Extrima can detect even minute leaks with pinpoint accuracy. Extensive tests have shown that using the Extrima can reduce the average time by more than 50 % for identifying, locating and repairing a leak on a fighter jet during maintenance.

It is certified for use in Zone 0, classification Ex ia, IIC T3 with ATEX, IECEx, TIIS, NEPSI and CSA certificates. The Extrima can be used to trace leaks using Forming gas (5% H₂/95% N₂) or in applications where pure hydrogen is used.

Features

Intrinsically safe: Ex ia IIC T3
High sensitivity 0.5 ppm/ 5E10^-7cc/s using 5% H₂/95% N₂
Waterproof: IP 67
1 minute start up time
Unique selectivity to hydrogen

Advantages

Intrinsically safe for use in hazardous areas (Ex ia IIC T3)
Robust enclosure for demanding field use
High sensitivity and fast recovery allow for efficient operation
