The DEWMAT 780 dewpoint sensor is a reliable and long-term stable dew point sensor for industrial applications.

It uses a completely new sensor technology delivering stable measurement signals, even when the humidity is very low, thus offering reliable and precise measurements up to dew temperatures of -100 ° C.

  • Dewpoint measurement down to –100 ° C
  • New sensor technology
  • Variant with integrated pressure measurement
  • Various output signals depending on the versions: 1 x 4 ... 20 mA, 2 x 4 ... 20 mA, RS-485 (Modbus), 4 ... 20 mA with loop power
  • IP65 enclosure offering protection in restrictive industrial applications
  • Very fast reaction times allow safe signaling when the limit values are exceeded
  • Direct installation in a dryer possible via ½ "thread
  • High precision, ± 2 ° C dew point.
