Product Manual Datasheet
Manual hydrocarbon and water dew-point tester for natural gas
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.
