John Morris Scientific is proud to announce the new intrinsically safe Sensistor EXTRIMA Hydrogen Leak Detector designed for use in potentially explosive environments.

The new portable EXTRIMA conforms to EEx ia, IIC T4 according to European ATEX and Class 1, Div 1, Groups A, B, C, D according to US standards. It is extremely sensitive and can be used to find leaks as small as 2 × 10^-6 mbar × l/s - comparable to leaks 1,000 times smaller than detectable with traditional soapy water or bubble tests.

Industrial applications include valve, joint, tank and pipe leak detection in petrochemistry, fuel tanks, Hydrogen fuel cells, Hydrogen plants and oil rigs. The EXTRIMA is also the first Leak Detector to pass the stringent requirements of the aviation industry and can be used for leak testing of complete fuel systems, oxygen supply and fire extinguishing systems, both in production and maintenance.

The recommended trace gas is a low cost standard mixture of 5% hydrogen and 95% Nitrogen available from major gas suppliers. This mixture is non-flammable, non-corrosive, non-toxic and environmentally sound.

The new EXTRIMA is based on modern microelectronics. The EXTRIMA is maintenance free because there are no moving parts such as expensive vacuum pump technology.

This extremely light leak detector is designed to withstand industrial environments, is water proof and dust protected (IP 67). The chargeable Lithium Polymer battery provides up to seven hours of operation.

Combined with the auto-range function and audible pitch, the new ergonomically designed hand probe with a built-in leak/no leak LED leak indicator allows for fast homing in on suspected leak areas. The clear display enables exact leak location and quantification.

The new Hydrogen Leak Detector H2000 is a unique instrument for industrial leak detection and tightness control.

It is extremely sensitive and can be used to find leaks as small as 5 × 10^-7 mbar × l/s, comparable to leaks 1000 times smaller than detectable with a traditional soupy water or bubble tests.

The inherent characteristics of Hydrogen enable fast, precise and safe leak location and qualification. Hydrogen leak detection is done with an extremely safe 5% Hydrogen in 95% Nitrogen gas mix. Because Hydrogen is quickly transported to the leaks and dissipates much faster than other gases it allows for much quicker testing and re-testing than other gases. Hydrogen is also a renewable gas, environmentally sound, certified as food additive and much cheaper than other gases for example Helium.

The Adixen Sensistor H2000 is small, robust and suitable for leak detection in tough factory environments. Leaks in wet objects can be detected when the probe is equipped with a protective cover. Background interference is minimised by the dynamic background compensation, with a useful auto-zero function.

The H2000 is based on modern microelectronics and because there is no expensive vacuum pump technology involved in the detection process the H2000 is virtually maintenance free.

The new 9012 XRS leak detector is a complete field-based system based on proven hydrogen tracergas detection technology. The 9012 XRS will detect any leak from major leaks visible with the naked eye to leaks that are so small you need a high performance microscope to see.

The inherent characteristics of Hydrogen enable fast, precise and safe leak location and qualification. Hydrogen leak detection is done with an extremely safe, non-flammable and food additive certified 5% Hydrogen in 95% Nitrogen gas mix. Because Hydrogen is transported so quickly to the leaks and dissipates much faster than other tracer gases it allows substantially faster results.

The 9012 XRS is often used for leak detection jobs on:

• Telephone Cables
• Gas-Filled Power Cables
• Petrol Stations
• Gas Pipelines and Cylinders
• Heating Systems
• Water Pipes (outdoor and indoor)
• Airport Fuel Supply Systems

The 9012XRS is extremely portable weighing only 2.5 kg, it is easy to use and features visual as well as audible leak signals. The 9012XRS is waterproof making it ideal for outdoor use and can be charged on the road via 12V charger.

The wide range of accessories includes duct probes, areal cable probes, ground probes, surface probes and probe wheeling carts.
