The Mountain High lighted oxygen gauges come in two sizes:
The EPG-600a fits a standard 57mm instrument hole.
The EPG-601a would fit into a 31.75mm cutout.
Both allow you to place the gauge anywhere you desire on the instrument panel making it much easier to keep an eye on your oxygen levels and keeping your high-pressure oxygen line out of the way. Ideal for people who spend a lot of their time mountain flying.
These Mountain High lighted gauges have a precision sin/cosin air core coil movement for ruggedness and accuracy through a wide voltage range (10 to 28 VDC). A small DE-09 connector on the rear of the gauge supplies all the connections needed.
Lighting is internal with optional or existing EL-strip lighting power supply. The EPSU600 2-wire (4-20 ma.current-loop) electric pressure sending unit has a SAE-4 boss. It can be mounted directly to the RCV/RVR, IPR, PCR regulators or our SAE manifolds. They can be used with any 4-20 ma. (0-3000 psi) current loop sending unit.
