Portable dew-point meter DewMaster

chilled mirrorwith data loggerwith LCD display

Description
Dewmaster Koffer ProChem Analytik® is a portable dew point mirror analyzer using field-tested chilled-mirror (dew point mirror) technology. The instrument accepts one-, two- or three-stage Peltier sensors (cooling ranges 45°C, 65°C or 95°C) which are user-exchangeable. Each device is delivered with a NIST traceable certificate. Measurement control and configuration are available via the front graphic display, front keyboard and RS232 interface. Multiple analog and serial outputs plus a pressure sensor input enable psychrometric calculations and integration into process systems.

Highlights / Features

• Field-tested dew point mirror (chilled-mirror) measurement principle
• Replaceable 1-, 2- or 3-stage Peltier sensors for different cooling ranges (45°C, 65°C, 95°C)
• NIST-traceable certificate supplied with every unit
• Control menu via front graphic display, front keyboard and RS232
• Automatic calibration function (ABC) with automatic mirror assignment correction and automatic optics adjustment
• Selectable interval for automatic optics adjustment to reduce measurement errors caused by contamination
• Two user-programmable alarms (configurable as hold alarm or normal alarm, Form C)
• Serial (RS232) and multiple analog outputs; programming via RS232 or front keyboard
• User-scalable outputs: 0–5 VDC, 0–10 VDC, 4–20 mA, 0–20 mA — up to 3 simultaneous outputs; scalable to psychrometric variables
• Pressure sensor input for psychrometric variable calculation
