The Raychem RAYSTAT-M2-G is a combined temperature and moisture sensor used with snow-and-ice-melting control systems for driveways, stairways and walkways. The IP68-rated head measures Ø60 mm and 32 mm high and reads across a −50 to 70 °C range. Ambient temperature and surface moisture are reported to the associated Raychem control unit for on-demand heater activation.
