Dew Point Transmitters and Dewpoint Sensors

Our range of standard and intrinsically safe dew-point transmitters and sensors are designed for long term, continuous use, online measurement of moisture content in gases and compressed air.
Many dewpoint ranges are available between -110C to +20C (-186F to +68F) dewpoint (or equivalent in ppm(v), g/m3 or Ib/MMSCF, excluding Model PDT - C/F only).
