This instrument is specially designed for real-time monitoring of the Insulation resistance value of the submersible power cable when delivery the ESP and the power cable into the oil-well downhole.

The instrument could automatically give the audio alarm when the real insulation resistance value of the submersible cable was decreased in case of any damage. Monitoring of insulation resistance at an early stage often makes it possible to discover faulty points and solve the problem in advance to prevent serious problems.
