No helium sensor to replace - ever!

Hi-tech analyzer for measuring  nitrox and trimix gases.  After inserting the analyzer adapter (included) to a bottle valve with a breathing mixture, the content of both oxygen and helium is shown as percentages directly on the display at the same time.

- Standard flow limiter for all valves.
- Worldwide Power Supply (also works with 9V battery - included)
- Hard and watertight Case
- Connection hose
- Ohmmeter plug-in
- Voltmeter plug-in
- Measuring cables

This trimx analyser reports "FOUL AIR" if the oxygen, nitrogen and helium can not be calculated due to contamination which is a major safety advantage over any other analyser.

  • OLED Display
  • Analyzer has built in Gas Mixing Calculator
  • Continous flow mixture measurement with Hi/Lo alarms for He and O2
  • new electronics with lower energy usage
  • Gas purity option serves for gas purity measuring.
    It is primary suited for argon, but after readjustment of the values it is possible to use for several different gases.
    It is also possible to detect ratio of two gases with different speed of sound. For example: helium/nitrogen, helium/argon, hydrogen/nitrogen, hydrogen/argon and many more.

Operation Principle

A standard electrochemical sensor (R-17D) normally used in analyzers for diving is used to determine the oxygen content. The helium content is determined on the basis of measuring the speed of sound in the analyzed mixture.

The speed of sound depends on the content of helium and oxygen, and on the temperature of the mixture. The dependence of the speed of sound on pressure is marginal and can be ignored under normal atmospheric pressure. At 0°C the speed of sound is approximately 970 m/s in pure helium, 330 m/s in air, and 315 m/s in pure oxygen. Raising the temperature by one degree raises the speed of sound by approximately 0.175%. The speed of sound in the mixture is described as a non-linear equation of temperature, oxygen content and helium content.

The speed of sound is measured directly as the time it takes for an acoustic impulse to travel between two microphones. This measurement is taken alternately in both directions to eliminate the influence of the gas flow-rate.

Every analyzer produced is tesed in the complete range of acceptable oxygen and helium values. It is tested in air, pure oxygen and pure helium as well as in 12 different calibration mixtures.
- Simple flow limiter for all valves.
- Worldwide Power Supply (also works with 9V battery - included)
- Hard and watertight Case.
-  professional flow limiter
-  connection hose
- spare set of O-rings
Pressure sensor - the analyzer can measure pressure in the tank and gas mixture at the same time
Ohm-meter plugin - to check bulbs and cables 
Voltmeter plug-in - to check batteries (lights, scooters...)

We have combined the best of Golem Gear Harness and Bacplate into an unbeatable combo:
Golem Stream Backplate
Inspired by expedition divers' minimalist needs and designed by traveling rebreather divers.

The Golem Stream backplate comes in Regular Profile shape (same as any other backplate) or in Reverse profile (pictured below) with an channel along the center of the BP. The chanel serves as an STA. 

Reverse profile Stream BP has 4 cam band slots in three rows for ultimate flexibility in configuration. holes at the bottom of the Backplate accomodate the ArmadilloCCR sidemount kit. Argon bottle can be attached to the the holes on the edges of the BP.

Select correct Backplate profile below.

This stainless steel backplate weighs only 2 lbs. It's unique reversed design will accommodate rebreather scrubber canisters as well as single tanks without the need for cumbersome and redundant adapters (STAs).

Can be quickly mounted with a pair of cam bands and will accommodate the Golem Gear Armadillo CCR and/or any brand of buoyancy wings.
The BP is 15 inches long by 11 inches wide.


The G2 adjustable diving harness is a streamlined webbing harness with all the standard D-rings. We added heavy duty SS adjustable buckles to shoulder straps. The straps can be loosened to don the rig and cinch the straps down. When removing, loosen the shoulder straps, open the buckle and walk out of the harness.
The buckles are heavy duty stainless steel used on Search and Rescue (SAR) harnesses world wide - if they can lift two people into helicopter they will hold the kit on your back. G2 HarnessOptionally, heavy duty SAR plastic buckles are available for light-weight travel setup.

Fits on any standard backplate or rebreather.
