CDP301 Condumax Dew-Point Tester

Manual hydrocarbon and water dew-point test for natural gas
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.
