PosiTector DPM L Series Dew Point Meter Logger
DeFelsko · SKU defelsko-POSITECTOR-DPML
A stand-alone logger with magnetic probes that attach to steel structures to monitor and record relative humidity, air and surface temperature, dew point, the surface-to-dew-point difference and wet bulb temperature. It connects over Bluetooth to the PosiTector App; the DPM L+ adds WiFi for remote monitoring and email alarms. It conforms to ISO 8502-4, ASTM D3276 and SSPC-PA7.
