DEWCHECKER 2.1

ADVANTAGES: 

  • Easy handling
  • High measuring certainty and accuracy
  • Insensitivity to gases containing dust and corrosive gases
  • Robust construction
  • Safe designation of dew point by detaining the temperature and finevon +/- 0,2°C adjustments in steps of +/-0,2°C

FEATURES:

The dew point measurement Dewchecker 2.1 is a portable device used for measuring 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 level of the dew point depends on the moistness of the measuring gas. Measurement inside the device is based on a cooled mirror the formation of condensate becomes visible on. Due to the direct measurement of the dew point temperature the measurement is accurate and long-term stable. The device itself requires very low maintenance. The main range of application of the device is the dew point measurement of gas atmospheres of heat treatment facilities and gas generators.

The Dewchecker 2.1 is equipped with an additional capacitive on-line sensor used accordingly for continuous measurements. The measurement result can be forwarded by an universal analog output or a digital RS-485 / RS- 422 interface.

The mirror temperature can be adjusted precisely by manually using +/- keys on the front panel. The device is available as 230 V or 115 V supply voltage version.
