Model DS2000
Single Channel On-Line Dewpoint Hygrometer
-1100C to +200C (-1660F to +680F)
A complete on-line solution for continuous
measurement of dewpoint in process gas and
compressed air, oering powerful functionality
via a simple interface.
The dewTEC Model DS2000 from Alpha Moisture
Systems is a single channel, online hygrometer
designed to accurately measure dewpoint
in process gases and dry compressed air.
This panel mounted dewpoint hygrometer
combines advanced digital technology with the industry
leading ultra high capacitance aluminium oxide sensors the acknowledged industry benchmark for trace moisture
measurement in industrial process gases.

The combination of advanced electronics and full specication sensors makes this the unit of choice for a
wide range of applications due to it's exibility and high congurability and ease of use through its menu
driven operation. The instrument can be factory congured to order and to read in °C or °F dewpoint,
ppm(V), g/m≥ or lb/MMSCF.
The measured dewpoint is displayed by means of a large 5½ digit, seven segment LED display. Model
DS2000 also oers two independent, fully user programmable alarm contacts and open collector outputs
to provide all the versatility required for any application. The factory set, analogue, current or voltage
output, that is linear with dewpoint, is available as well as RS485 serial connection with 1-99 address
settings. The dewTEC DS2000 is a fully self-contained display system in 1/8 DIN panel mounted case providing front panel protection to IP66 (NEMA 4).
The dewTEC DS2000 can be supplied together with any one of a range of dedicated, ultra high
capacitance, sensors incorporating automatic calibration and covering an overall range from -1100C to
+200dC dewpoint. The sensor has been conditioned for long term stability so ensuring a long and trouble
free service life. Additionally the high sensitivity and linear output of the sensor allows up to 1km cable
length between the Sensor and the dewTEC DS2000 instrument. The sensor is ATEX certied for intrinsic
safety and so can be used in hazardous environments with a suitable Zener barrier in the safe area.
