Overview
The EdgeTech DewMaster is a chilled-mirror dew point hygrometer designed for industrial and laboratory measurement of gas moisture. Available with one, two or three-stage sensors (integral or remote), it provides primary dew point measurement with a NIST-traceable calibration certificate. Multiple outputs and a pressure input enable integration into process control and calibration systems.

Highlights

• Field-proven chilled mirror measurement technology.
• One, two or three-stage cooling options (integral or remote sensors).
• Front-panel scrolling menu with RS232 for configuration and data output.
• Depression range choices: 45, 65 or 95°C depending on cooling stages.
• Automatic Balance Control (ABC) corrects for mirror contaminants and supports scheduled restandardization.
• Dual programmable alarms with latching or auto-reset and Form C contacts.
• Serial and scalable analog outputs available simultaneously (0-5 V, 0-10 V, 4-20 mA, 0-20 mA).
• Pressure transducer input for psychrometric calculations.

Standard Features

• Primary chilled mirror measurement of water vapor in gases.
• Measures dew point, frost point, moisture %, temperature and derived psychrometric variables.
• Wide measurement ranges and optional high-accuracy models (±0.2°C TP standard, ±0.1°C TP optional).
• NIST-traceable calibration; user-selectable restandardization intervals.
• Graphic display, analog outputs and RS232 communication included.

Application Areas

• Annealing furnaces and thermal processing lines
• Process dryers and drying ovens
• Clean rooms and controlled environments
• Curing ovens and stability chambers
• Plant compressed air and gas systems
• Environmental and test chambers
• Laboratory calibration standards and metrology
• Emission testing and continuous industrial processes
