Title: D-Zero Instrument Air System Humidity Transmitter Evaluation

This report shows the findings that resulted in the purchase of the optimum dew point hygrometer for use in the D-Zero instrument air system (see diagram 2 on page 9). The hygrometer will monitor the air syste m to insure that the dew point level does not go above the normal operating output of the driers (this precise value will be determined during initial system start-up). The following criteria was used in the evaluation: (1) Long term durability; (2) Minimum calibration; (3) Indicate a dew point level down to -40 C accurately; (4) Designed to work in a low humidity region; (5) Minimum maintenance; (6) Fast response time; and (7) Lowest cost provided all other criteria is met.
