Portable Dew-Point Tester – Michell CDP301

Manual hydrocarbon and water dew-point tester for natural gas

Key features

  • Fundamental cooled-/chilled-mirror dew-point measurement principle
  • High-definition color LC display
  • Visual identification of both water and hydrocarbon dew point
  • Automatic mirror cooling rate control according to ISO 6327 and ASTM D1142 test methods for natural-gas dew-point measurements
  • Self-contained, rechargeable battery powered
  • Exd certified IECEx ATEX UKCA Zone 1 IIB+H2 T3
  • 100 barg operating pressure rating
  • Greater than 60˚C measurement depression range (up to 100 barg pressure)
  • Better than +/-0.5˚C accuracy of mirror surface measurement


CDP301 portable HCDP tester uses the chilled mirror principle for both hydrocarbon and water dew point measurements and is designed to follow the requirements as described in ASTM D1142. Based on the visual manual method of observing the formation of condensate, the CDP301 uses a high-definition visual image to assist users and allows image capture and reliable logging of measurements for later review.
