DATA SHEET and USERS MANUAL

1011C_1_new

The 1011C Aircraft Hygrometer is a complete chilled mirror optical dew point system for monitoring atmospheric dew and frost points. It provides three stages of thermoelectric cooling, and can reach frost points as low as -60 to -90 °C, depending on mounting configuration and operating conditions. No auxiliary coolants are required.

Included in the 1011C system are a water excluding inlet probe and a pressure tap for monitoring static pressure. A cockpit digital display with resolution to 0.1 °C is provided, as well as analog and RS-232 outputs for recording. The 1011C is a complete reworking of the 1011B formerly manufactured by Buck Research Instruments under license from General Eastern Instruments.
