Product Description
The Edgetech DewMaster is a precision chilled mirror hygrometer designed for critical applications requiring accurate and reliable dew point measurement. It is available with single, dual, or three-stage sensors, providing a choice of 45, 65, or 90°C depression to cover a wide measurement range from -75 to 100°C . This flexibility allows the DewMaster to be configured for diverse needs, from standard humidity monitoring to demanding industrial processes.
A key feature is the Automatic Balance Control (ABC) system, which automatically corrects for the effects of mirror contaminants and re-standardizes the instrument, significantly extending periods of unattended operation and reducing maintenance . Users can program the time and interval of this re-standardization for optimal convenience.
The DewMaster offers extensive connectivity with serial and analog inputs, and RS232 communications for remote programming and data output, including dew point and alarm status. It features dual user-programmable alarms that can be set for latching or auto-reset mode. An integrated pressure transducer input enables the calculation of various psychrometric variables, and an optional explosion-proof sensor housing is available for hazardous environments .
