DeFelsko PosiTector DPM (Dew Point Meter)
The PosiTector DPM (Standard or Advanced) continuously displays and logs humidity, ambient and surface temperatures, dew point, and Ts – Td. Its rugged, IP65-rated housing, large touchscreen, and networking options make it ideal for field and lab environments where environmental conditions must be controlled.
Features
Each set includes a long-form calibration certificate with material test report
Durable construction with corrosion and wear resistance
Supports both mil/inch and mm versions for diverse use cases
Imperial ±1 mil; Metric ±0.025 mm (or other tolerances depending on block)
Designed specifically for verifying UTG (ultrasonic thickness) probes
