The PPS71 Geothermal Memory Gauge is designed for extreme high temperature downhole conditions. Our robust electronics combined with vacuum flask technology allow this product to perform at up to 600 deg.F (315 deg.C). As a general reference, this tool could operate 8 hours at 300 deg.C environment. This product works the best together with our slickline depth system (PPS36 DepthWatcher).
