DEWCHECKER 0.1

FEATURES:

The dew point measurement instrument Dewchecker 0.1 is a portable device used to measure the dew point of gases. Per definition, the dew point is the temperature of a body marking the start of condensation of water vapor on its surface respectively the balance adjusted between condensing and evaporating water.
The gas sampling occurs via a gas sampling fitting furnished in the hot zone to the furnace wall with a ceramic inner tube.

Due to a steel tube length of at least 150 mm, outside the furnace wall, the sample gas is cooled quickly and guided at a gas dew point temperature below room temperature through a dense gas hose to the gas inlet port of the device.
The Dewchecker 0.1 is equipped with a capacitive on-line sensor used accordingly for continuous measurements. The measurement result can be forwarded by a universal analog output or a digital RS-485 / RS-422 interface.
