The E Series Dew Point Sensor is rated IP67, making ideal for outdoor use. It measures dew point, temperature and relative humidity of compressed air and inert gases (argon, carbon dioxide, carbon monoxide, helium, hydrogen, nitrogen and oxygen). The sensor comes with a touch screen display, alarm relay and two output options – 4-20mA and Modbus.

Best suited to

  • Indoor or outdoor use
  • Compressed air and gas systems to 4 Mpa (600psi)
  • Membrane, drum, hybrid, refrigerant or desiccant dryers
  • Temporary or permanent measurement

Important

  • A minimum flow rate of > 1L/min is required for the sensor to read accurately
  • The sensor must be installed in an upright position, after the dryer.
  • Incorrect installation can damage the sensor and void the warranty. If you aren’t sure how to install, please contact us. Full installation instructions are available in the User Manual. 

Dew Point Sensor comes with

  • Measurement Chamber with adjustable silencer and removable Nitto type quick connect
    (contact us for other measurement chamber options)
  • Calibration certificate
  • User Manual
  • 12 month warranty

Options for the Dew Point Transmitter

  • Dew Point Range
  • Integrated pressure sensor: 0 to 17 bar (242 psi)

Warranty & Calibration

12 month warranty

Calibration is recommended every 2 years (provided the sensor is not exposed to relative humidity above 85%).
Annual calibration is required if the sensor is exposed to relative humidity above 85%.
