The PPS71 PTS-C Geothermal Tools are designed for extreme subsurface 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, temperature, casing collar location, and flow profile and can be configured as either a memory tool or surface read out tool (SRO) tool. 

The measurements are done with a highly accurate silicon-sapphire (piezo) transducer, a fast response resistance temperature detector (RTD), the customer’s choice of either a continuous or full bore spinner flowmeter and a highly sensitive CCL. 

The CCL has a magnet and central coil arrangement which amplifies current providing a readable voltage spike or “collar kick” as data, giving end users an important control for depth correlation.
Features
