1.0 General Description & Features
1.1 Description
The
dewTEC DS2000 is a DIN style panel mounted dewpoint meter, designed to accurately
measure the dewpoint in gas or dry compressed air. The operating range of the unit is factory
set to the Moisture Sensor supplied with the unit. Process moisture value in factory set units
of °C, °F or PPM(V) is indicated, by the
dewTEC DS2000 dewpoint meter, on a large five
digit seven segment display
The main external body of the Ultra High Capacitance Moisture Sensor is made of plated steel
and a stainless steel filter guard protects the sensing element within it.
The sensor can be located up to one kilometre away from the dew point meter.
