Temperature is a very important parameter to control for evaluating the influence of the thermal effects on the masurements and on the structure which is monitored. Thermometers are available with platinum RTD (Resistance Thermal Detector) and thermistor probes. Both models are housed in a shock resistant stainless steel body to be embedded in concrete. Portable thermal probe is available for water temperature measurements in wells, boreholes and standpipe piezometers. Temperature values are directly displayed in °C on the reel face-plate.
