Description
The KPerm™ Quartz Permanent Downhole Gauge is a permanently installed inside the Probe’s solid gauge mandrel. The permanent gauge delivers continuous high accuracy pressure and temperature data to surface where it is displayed real time via a surface readout. The gauge is internally and externally Ebeam welded and designed for maximum shock and vibration resistance to enhance the reliability and performance.
