Purpose:

The instrument is suitable for geophysical logging in the coal field, metal and nonmetal mining, hydrology, and drilling field. It can record different parameter curves at a paper of 15 mm in width. It can be used independently or with other instruments to record various curves. It is composed of recorder, power supply, measurement range controller, depth indicator, stabilized power supply, winch and pulley.
