With built-in Ambient RH + Temperature sensor; Plug-in Contact Temp Probe (optional) providing the best available accuracy tolerances; optional plug-in Relative Humidity Probes or Hygro-i2 RH probes for measuring Equilibrium Relative Humidity, Temperature, Dew Point and Humidity Ratio in structural materials. A structural material such as a concrete slab can be tested using the in-situ method or RH Hood methods (International Standards: ASTM F2170 & BS 8201, 8203, 5325).
