FID instruments are supplied with an 85 cc hydrogen gas tank. This tank,
which may be pressurized to 2200 psi maximum at 25×C, will provide 10
hours operation when fully charged. The tank has an integrally mounted
high pressure gauge that can be easily read when the tank is in or out of the
instrument. Install the tank in the instrument by inserting it into the
receptacle on the top and tightening (left hand threads tighten
counterclockwise) until the rubber tank boot is flush with the instrument
sidepack and a slight resistance is felt.
