The H Series Dew Point Sensor is a portable / hand-held sensor. It measures dew point, pressure, temperature and pressure dew point of compressed air and inert gases (argon, carbon dioxide, carbon monoxide, helium, hydrogen, nitrogen and oxygen). The handheld Dew Point Sensor is best suited to temporary measurements and is ideal for service technicians and auditors.

Important

  • A minimum flow rate of > 2L/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
