Hydrogen Leak Detector

Extrima®

Ex-Certified Hydrogen Leak Detector

Extrima-Ex-certified-Hydrogen

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).

Extrima allows you to quickly detect leaks across a wide range of industrial systems where pure hydrogen is used—such as hydrogen systems, hydrogen-cooled generators, fueling stations, and fuel systems—without compromising safety. It can also be used on components like valves, regulators, and pressure gauges, where a non-flammable gas mixture of 5% hydrogen in nitrogen is used as a tracer gas. The unit is specifically designed to meet the rigorous requirements of the energy sector where hydrogen is used in production, storage, distribution, and consumption. Thanks to its high sensitivity, Extrima can detect even minute leaks with pinpoint accuracy.

It is certified for use in Zone 0, classification Ex ia IIC T3, with ATEX, IECEx, TIIS, NEPSI, and CSA certificates. 

Features

  • Intrinsically safe: Ex ia IIC T3
  • High sensitivity: 0.5 ppm / 2.5 E-8 mbar·L/s
  • 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
  • Finds leaks in high-hydrogen backgrounds
  • Portable, battery operated (more than 8 hours of use per charge)
  • Low cost of ownership
