Model DS1200-AMT
Single Channel Dew Point Hygrometer
Ranges available between -1200C to +200C (-1660F to +680F) dewpoint
User friendly solution for continuous on-line dewpoint
measurement in dry process gases and dry compressed
air, oering powerful functionality and simple interface
through advanced digital technology.

Fast Response - Stable - Reliable Accurate - Easy to Install.
Model DS1200 from Alpha Moisture Systems is a single channel
on-line hygrometer designed to measure dewpoint in process
gases and dry compressed air. The panel mounted ⅛ DIN
dewpoint meter, providing panel protection to IP65 (NEMA4X),
combines with the Model AMT range of ultra high capacitance
sensors for accurate trace moisture measurement.

Combination of advanced digital technology of the display electronics and the transmitter, makes this the
system of choice for a wide range of applications where precise indication, control and monitoring is critical.
Model DS1200-AMT system can be factory congured to read in °C dewpoint, °F dewpoint, ppm(v), ppb(v),
g/m³ or lbs/MMSCF. The measured value is displayed on a large 4 digit, 13.8mm high, fourteen segment
LED display. Model DS1200-AMT Dewpoint Hygrometer is fully congured to the customer's specications.
The instrument oers two fully programmable alarm relays, which can be independently set across the
full operating range. An optically isolated analogue signal, linear with the measured unit is also available
(to interface with any external device).
Model DS1200-AMT can be supplied with any one of a range of dewpoint transmitters, which have all
been specially manufactured to provide long term stability, so ensuring a long and trouble free service life.
The long lasting sensing element oers excellent sensitivity, repeatability and response speed - especially
on dry down. Integrated electronics in each transmitter allow calibration data to be stored within its
memory, making transmitters completely eld interchangeable.
Each transmitter is calibrated to provide overall system accuracy of better than ±2°C dewpoint and
supplied with a certicate traceable to international humidity standards.
Model DS1200-AMT also incorporates the invaluable “AUTOCAL” feature for easy eld verication of the
system response, without recourse to any additional equipment. Accidental or unauthorised operation is
prevented by a simple initiation routine.
The system allows the display unit to be sited in excess of 1000m from the transmitter, connected by a
simple twisted pair cable.
