Instructions for use:

1. Use the Pressure slider to specify the measured gas pressure

2. Use the Temperature slider to specify the temperature of the gas 

3. Read the pressure of the gas compensated to 68 ℉ (Standard temperature)

4. (Optionally) Use the Barometric Pressure or Elevation slider to specify the barometric pressure for refining gauge pressure measurement - critical for gas weight calculations

Alternately, to aid in gas handling operations:

1. Use the Temperture slider to specify the temperatue of the gas used for filling equipment

2. Use the Pressure slider and the Compensated Pressure to determine the fill pressure at the given temperature that matches the fill pressure at 68 ℉ specified by the equipment manufacturer
