The principle of current method and voltage method is used to detect casing CT conveniently.

Support the detection of CT and CT.

All testing items can be completed on a single computer without additional auxiliary equipment.

It has a miniature fast printer and can print test results directly on the spot.

Intelligent controller, simple operation.

Large screen LCD, graphical display interface.

The inflection point of CT/PT (excitation) is given automatically according to the regulation.

The error curves of 5% and 10% are given automatically.

It can save 3000 sets of test data without loss after power failure.

Supporting U-disk to save data, can be read by standard PC, and generate test reports.

It's compact and portable < 22Kg, which is very convenient for field test.
