Application of the Hygrometer (900-901D1)

Comparison of PPM

Calculations

There are three basic methods for determining the moisture
content of a gas in PPM

•

the calculations described in this appendix

•

calculations performed with the slide rule device that is
provided with each GE Panametrics hygrometer

•

values determined from tabulated vapor pressures

For comparison purposes, examples of all three procedures are
listed in Table A-4.
