The PPS71 PT Geothermal Tools are designed for extreme, high temperature downhole conditions. The robust electronics combined with vacuum flask technology allow these products to perform at 350 °C (662 °F) continuously, for four hours. The tool measures pressure and temperature, and can be configured as either a memory tool or surface read out (SRO) tool. The measurements are done with a highly sensitive silicon-sapphire (piezo) transducer and a resistance temperature detector (RTD). The RTD is exposed to the well fluids for faster response and higher accuracy.
