DCH series Array Electro-magnetic Thickness Instrument is used to measure the thickness of downhole metal pipe, which can reflect the corrosion degree of casing.

The Electro-magnetic Defect Detection Instrument have successfully resolved the problems of detecting the thickness, corrosion, deformation, cracks and other problems of casing in tube.

The Gamma is used in surveying natural radioactive strength in formation. It makes use of NaI to detect gamma photon, and change to lower-power photon.

TLX65-200D Gyro Consecutive Inclinometer is a combinative consecutive inclinometer. It can be used independently in measuring well track, window cutting in sidetrack drilling or connected with other downhole instruments.

The Multi-arm Caliper Tool adopted mechanical detection arms to detect the inside diameter (radius) , judging the distortion, transposition, holes, cracks, inside wall corrosion and other casing damages through the diameter (radius).
