Purpose:
The instrument is a new digital inclination measurement instrument of high precision. It is suitable to determine dip angle and azimuth angle of vertical borehole or directional borehole in high precision. It can also determine dip angle, azimuth angle, tool face angle and depth of borehole in high precision. It has been widely used in the engineering, hydrology, oil field, coal field, and geology.

The instrument is composed of controlling case, and inclinometer probe. It is portable. It adopts test data coded long distance transmission techniques, so it can transmit test data through cable accurately and reliably; combines a high performance sensor with digital signal processing techniques, so its test data are in high precision and good stability; Uses a ultra-brighten LCD for display, so it is intuitive and clear; Equipped with a printer to print out test data at determination field; it can determine depth of borehole during inclination determination. It is easy to be operated and it is suitable to be used at determination field.
