Precision Chilled-Mirror Dewpoint Hygrometer Features and Benefits A primary measurement instrument, ideal for laboratory and precision applications 3 Stage Chilled Mirror Hygrometer, with integral cooling Precise measurement to -95 °C frost/dew point, 37 ppb(V) High accuracy instrument (±0.2 °C dewpoint) for laboratory or similar applications Backlit LCD displaying readings in °C or °F dewpoint and ppm(V) Optional temperature and pressure sensors are available RS232 Serial comms Pressure measurement can be displayed using the optional pressure transducer 2 programmable alarm relays Automatic Balance Control (ABC), for fast and easy measurement and control Supplied with a Calibration Certificate traceable to National and International Humidity standards CMH-RPC Precision Chilled Mirror Dewpoint Hygrometer accurately measures the dewpoint of a gas by cooling a mirrored surface, over which the gas flows until a layer of dew forms on the surface. Bench or Counter Top Standing - Front panel access to all main components including mirror cleaning - Fast Response Stable - Reliable - Quick Installation. The Chilled Mirror Dew Point Hygrometer utilises a 3-stage cooler combined with an integral refrigeration unit to measure the dewpoint in gases from below -95 °C to +20 °C (-139 °F to +68 °F) dewpoint with an accuracy of ±0.2 °C dewpoint. This primary measurement principle makes the CMH-RPC the ideal instrument for laboratory, scientific, and research applications and a reference instrument for checking and dewpoint calibration of Dewpoint Meters, Dewpoint Transmitters, Dew Meters and Dewpoint Analysers.
