Compact dew-point meter DewTrans CR

chilled mirrorwith external sensorIP65

Overview
The DewTrans CR is a dew point mirror moisture analyzer for precise measurement of humidity, dew point, ambient pressure and temperature. It features a stainless steel measuring chamber and chemically protected optics suitable for demanding industrial environments. Displays and analog outputs (configurable by the user) allow flexible integration and monitoring.

User-specific configuration
The instrument is available in a remote version and can be adapted to customer requirements. Options include:

• Barometric pressure sensor
• Separate temperature sensor
• High accuracy ±0.1 °C option

Sensor
The DewTrans CR uses a wear-free, low-maintenance dew point mirror. Maintenance is limited to occasional mirror cleaning; the design ensures long sensor life and stable, repeatable measurements traceable to N.I.S.T.

Installation
The unit can be supplied as a compact instrument or with remote electronics for flexible installation and easy access during maintenance.
