Dew Point Meters
Dew point meters establish the temperature at which moisture will condense, the decisive check before coating: ISO 8502-4 requires the substrate to sit a safe margin above the dew point to avoid flash rusting and adhesion failure. Instruments such as the PosiTector DPM read air temperature, relative humidity, surface temperature and the surface-to-dew-point spread in one pass, with logging models for unattended monitoring.
