The DS1200 Dewpoint Hygrometer is a panel-mounted single-channel Indicator specifically designed to work with an Alpha Moisture Systems online Transmitter for continuous trace moisture measurement in gases, dry compressed air, and dry rooms/chambers.

The instrument can be factory configured to read in °C dewpoint, °F dewpoint, ppm(V), ppb(V), g/m³ or lbs/MMSCF. The measured value is displayed on a large four-digit LED display.

Key features include a selectable 0-20 mA or 4-20 mA isolated retransmission signal and two programmable alarm relays that can be independently set within the operating range of the Transmitter.

The DS1200 Dewpoint Hygrometer is our entry-level Indicator, offering simplicity and functionality for most routine applications. Our fully-featured DS4000 will satisfy more advanced applications requiring a user-configurable display and greater versatility.
