Benchtop dew-point meter DewTrans DPM-S2-S

portablechilled mirrorwith LCD display

Short description
The DewTrans DPM-S2-S is a dew point, moisture and temperature analyzer for gas applications, relying on a field-proven two-stage dew point mirror technology. The mirror sensor can be exchanged on the electronics. Each unit is supplied with a NIST-traceable calibration certificate.

DewTrans Highlights

• Stable, accurate and repeatable measurements with NIST traceability.
• Operating and programming via RS232; optional datalogger available.
• Two-stage Peltier cooling with sensor cooling range up to 65°C.
• Automatic mirror matching to compensate contamination and maintain measurement reliability:
  • Automatic correction of mirror assignments.
  • Automatic optics matching with configurable interval.
• Two user-programmable alarms (configurable as latching or normal).
• Serial (RS232) and analog outputs; 2x user-scalable 4–20 mA channels.
• Optional pump and rechargeable lithium-ion battery for independent measurement points.
