AT25 Electronic Logging Thermometer Gauge

 

Application Area

 

Model AT25 Electronic Logging Thermometer is mainly used in production well logging in oilfields. It is capable of measuring down-hole temperature profile in production wells, water-injection wells and gas-injection wells for temperature test, leakage and channeling detection, etc.

 

Features

 

1. The tool is powered by single power supply and signals are output in pulses. It is characterized by stable signal output, high sensitivity, good linearity, small temperature drift and quick temperature sensing.
2. It can be connected to any surface computerized logging system.
