Next-Gen Precision for Trace Moisture & Dew Point Analysis

The Portable Dew Point Meter Q-DPM70 represents the new generation of intelligent trace moisture measuring instruments. Harnessing advanced digital signal processing, this device delivers laboratory-grade accuracy for temperature, humidity, and dew point measurement in a rugged, portable package.

Unlike traditional analog meters, the Q-DPM70 stores calibration data directly within the Smart Probe. This eliminates the need for recalibration when switching probes and ensures that cable attenuation or interference never compromises your measurement accuracy.

Industrial Applications

⚡ Power Plants & SF6 Gas
Critical for monitoring trace moisture in SF6 insulated switchgear and transformers to prevent arcing and equipment failure.

🏭 Metallurgy & Compressed Air
Ensure the dryness of protective gases in furnaces and monitor compressed air quality in pneumatic systems (up to 20 bar).

💊 Medical & Environmental
precise humidity control for pharmaceutical manufacturing, grain storage, and health quarantine environments.

✔
Smart Probe Technology: Calibration data is stored in the probe's memory chip. You can swap probes instantly without needing to send the main unit back for recalibration.
✔
Interference-Free Transmission: Digital signal transmission ensures that long cables or environmental noise do not affect measurement accuracy.
✔
Comprehensive Data Display: Simultaneously displays Dew Point (Td), Moisture Content (ppm), Temperature (°C/°F), and Relative Humidity (%RH).
✔
High Pressure Capability: The stainless steel probe and connectors are rated to withstand pressures up to 20 bar (290 psi), making it suitable for pressurized pipelines.
