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 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 sensor, 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 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 4 digit, 13.8mm high,
fourteen segment LED display.
The instrument offers two fully programmable alarm relays, which
can be independently set across the full operating range of the
sensor. An optically isolated analogue signal, linear with the
measured unit, is also available to interface with any external
Model DS1200-AMT can be supplied with any one of a range of
sensors, 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 offers excellent sensitivity,
repeatability and response speed - especially on dry down.
Integrated electronics in each sensor allows calibration data to be
stored within its memory, making sensors completely field
Each sensor is calibrated to provide overall system accuracy of
better than ±2°C dewpoint and supplied with a certificate
traceable to international humidity standards.
Model DS1200-AMT also incorporates the invaluable
“AUTOCAL” feature for easy field verification of the system
response, without recourse to any additional equipment.
Accidental or unauthorised operation is prevented by a simple
The system allows the display console to be sited in excess of
1000m from the sensor, connected by a simple twisted pair
Model DS1200-AMT Dewpoint Hygrometer is fully configured
according to the customer's specifications and is supplied
complete with 2 metres of connecting cable and user manual.
For ease of installation, an optional flow through sample cell can
be ordered together with suitable pipe connections.
