Dewpoint Meter H4001- w/ Humidity and Surface Temperature probes w/ Certificates: ISO 8502-4:

Dewpoint Meter H4001 enables testing for the estimation of the probability of condensation on a surface to be painted and establishing whether conditions at the job site are suitable for painting or not. Relative humidity of the air and the steel surface temperature are the basis for the estimation of the probability of condensation. The steel surface temperature generally should be at least 3°C above the dew point when paints are applied. Below this temperature the Dewpoint Meter will sound an alarm and the display color will change to warn you that the surface conditions are not suitable too paint. Measurements of relative humidity, dew point, air temperature are shown. Surface temperature and surface temperature proximity to dew point are shown when using the surface temperature sensor. Interchangeable Humidity Sensor and Surface Temperature Probe allow the user to replace damaged or out-of-calibration-date Sensor and Probe. The Calibration Certificates with traceability to UKAS are an optional extra. The Certificates are supplied as hard copy and are available online through the Calibration Management Cloud (under Calibration) on our website. It is supplied in an industrial foam-filled Carrying Case with a Humidity Sensor and Surface Temperature Probe.
