Chilled Mirror Dew Point Hygrometer A Precision Dew Point Hygrometer for Industrial and Process Applications. The Edgetech Instruments DewTrak ll Dew/frost Point/ Humidity Transmitter is a compact, cost effective, primary method chilled mirror hygrometer designed to continuously measure the moisture content of gases. Housed in a weatherproof enclosure, its modular design is available in a variety of mechanical configurations to accommodate a wide array of applications. The DewTrak II provides high accuracy with long term stability and repeatability. It uses the chilled mirror dew/ frost point temperature condensation principle to accurately determine the water vapor concentration in gas mixtures. The result is a highly precise yet durable moisture measurement device with a very long life cycle. The DewTrak II is available with either the Edgetech Instruments D Sensor or the higher performance DX sensor. Either may be mounted directly to the hygrometer’s chassis for ambient air monitoring or they may be mounted remotely for insertion into glove boxes, HVAC ducts, environmental test chambers, circulation pipes, refrigerated storage rooms, engine test chambers and many other environments. Features: Precision dew/frost point or relative humidity transmitter Primary method chilled mirror sensor requires no calibration Provides high accuracy Long life, easily serviceable sensor Rapid response that quickly detects any change of conditions No false readings or accuracy drift Low cost of ownership Remote insertion or local wall mount sensor Flexible installation options Available with or without display Configurable analog outputs and alarm relay options Bi-directional serial interface Communications adaptable to user requirements Multiple display parameters: Dew/Frost point temperature in °C or °F Percent relative humidity Parts per million by volume Parts per million by weight Grams per kilogram Grams per cubic meter Grains per pound Wet bulb temperature DewTrak II Hygrometer With the DX Sensor Applications include: HVAC duct systems Critical purged atmospheres Glove box environmental chambers Pharmaceutical testing and isolation chambers Engine air intake and exhaust testing Modified atmosphere packaging Semiconductor manufacturing furnace and lithography Medical packaging Dryer efficiency Biologics and cell culture Fluidized beds Food storage and packaging Air make-up for clean rooms and data centers.
