The environmental conditions during pre-treatment and application of a coating system are major factors affecting the long-term performance of coatings on steel structures. The redesigned PosiTector Dew Point Meter from DeFelsko Corp. measures and records climatic parameters including relative humidity, air temperature, surface temperature, dew point temperature and the difference between surface and dew point temperatures. The instrument can be used for surface preparation as required by ISO 8502-4 and ASTM D3276.

New features include a larger, easy-to-read backlit display; Smart Trend™ Indicators to identify rising, falling or stable readings; a graph mode to chart all five parameters for quick analysis; and increased memory capacity to store up to 2500 datasets in 100 batches.

In addition, the instrument converts to accept various optional K-type probes, including magnetic and hand-held surface temperature probes. The optional Magnetic Surface Temperature Kit allows the instrument and a surface temperature probe to be attached onto steel structures for hands-free recording.
