Compact dew-point meter DewP

portablewith data loggerwith external sensor

Product Overview
The DewP is a portable dew-point analyzer designed for fast, accurate and economical trace-level humidity measurement in gases. Intuitive operation and a large LCD make setup and field use straightforward. Measurement display selectable as dew point (°C) or moisture (ppmv).

Description
Measuring range
The instrument provides a selectable measuring range from -100°C to +20°C dew point; other ranges available on request.

Data outputs
Standard 4–20 mA analog output for moisture; optional internal datalogger for recording up to specified cycles.

Sensor with long operating life
The LDT capacitive sensor uses advanced nano-pure technology to ensure stable long-term performance with low maintenance.

Calibration
Calibration for trace humidity measurements should be performed using calibration gas and a suitable reference device (dew-point mirror recommended for field verification).
