Extrima®
Ex certified Hydrogen
Leak Detector
Safety delivered

The fastest, intrinsically safe
leak detector
The portable Extrima Ex certifiedHydrogen Leak Detector is theultimate explosion proof instrument
for pinpointing leaks in the
toughest of environments, including
hazardous locations such as Zone 0(corresponding to Division 1).
The Extrima Leak Detector brings theunsurpassed accuracy, flexibility andsimplicity into a new range of demanding
applications. Certified for use in Zone 0,classification Ex ia, IIC T3 (with ATEX,IECEx, NEPSI and CSA certificates), itis the ideal choice for applications withextremely high demands for tightness
and safety, such as:• Process Industry — Extrima allows
for fast pinpointing of leaks on pipe
systems, valves, containers etc., in bothproduction and service• Aerospace — with Extrima, the aviationindustry has a safe, accurate andyet simple solution for leak testing ofcomplete fuel, cooling and oxygen
supply systems. Extensive tests have

ADVANTAGES AT A GLANCEn Intrinsically safe for use in hazardous areas (Ex ia, IIC T3)n Robust enclosure for demanding field usen

 High sensitivity and fast recovery allow for efficient operationn Low and easy maintenancennn Portable, battery operated (more than 8 hours of useper charge) Sensor change in less than a minute Incorporates the proven Sensistor sensor technology
developed for using forming gas (5% hydrogen in nitrogen)as tracer gas

Thanks to its small size, low weight andbattery capacity, the Extrima can easily
be used in confined space areas such as
aircraft fuel tanks.

shown that using Extrima minimizes
expensive downtime and reduces theaverage time by more than 50% for
identifying, locating and repairing a leakon a fighter jet during maintenance• Offshore — high demands on safety
and harsh environmental conditions
make Extrima the ideal instrument forleak detection on pipes, valves andcontainers, both in maintenance andassembly situations on oil rigs andrefineries• Power production — thanks to its highsensitivity, Extrima can detect evenminute leaks on hydrogen or liquid
cooling systems, with pinpoint accuracy

BROAD RANGE OF ACCESSORIES TO ADAPTTO A MULTITUDE OF SITUATIONS
A complete set of tools which simplifies tracer gas
injection, back streaming and locating leaks in fuel tanks: Injection Paneln  Injection Pads

FAST HOMING IN ON
SUSPECTED LEAK AREAS

USES ENVIRONMENTALLY FRIENDLY
TRACER GASHigh sensitivity, short recovery
time and auto-range function
allow for fast and accurate
location and quantification ofeven minute leaks.

Extrima uses an inexpensive standard forming gas (5% hydrogenin nitrogen) which is non-flammable, non-corrosive, non-toxic anddoes not damage the enviroment. This gas mixture is available
from almost all gas suppliers. Leak detection with hydrogentracer gas is a clean and dry test method.

ERGONOMIC HAND PROBE
The PX57 Flex Hand Probe is ergonomically designed and has
a built-in leak/no leak indicator for exact leak pinpointing. The
sensor, which can be easily protected against fluids, is placedat the probe tip allowing for easy replacement in less than aminute. The PX57 Hand Probe is available also with a rigid neck.

PORTABILITY INCREASESCAPABILITIESExtrima has a shoulder strap andprobe cables of 3 and 5 m (9.8 and16.4 ft) which extend the detection
possibilites in narrow spaces.
