Description
The Quantum™ Geothermal PT gauge is a subsurface high temperature memory tool designed to continuously measure and record downhole pressure and temperature. The PT gauge has excellent thermal protection from temperatures up to 350°C. A fast response temperature sensor (RTD) provides a high accuracy temperature profile of the well. Communication is via USB interface and the tool is powered using AA cell batteries.
