Purpose:

The instrument is a new inclination measurement instrument in high precision. It is used to determine dip angle and azimuth angle of vertical borehole or directional borehole. It can also be used to determine dip angle, azimuth angle, tool face angle and depth of borehole accurately.

It is suitable to determine inclination of borehole, which is more than 54 mm in diameter, and up to 2500 in depth, in the non-magnetic area. It can be widely used in engineering, hydrology, coal field, oil field, and geology.

The instrument is composed of laptop (optional), controlling case and inclinometer probe. It adopts test data coded long distance transmission techniques, so it can transmit test data through cable accurately and reliably; It combines a high performance sensor with digital signal processing techniques, so test data is in high precision and good stability; It can upload test data to a laptop through RS232 serial port, so it can show test data, plane diagram, sectional diagram, side projection diagram clearly and intuitively, and it can save test data; if connect to a printer, it can print out test data, plane diagram, sectional diagram, side projection diagram, and space trace diagram; It can determine borehole depth during inclination measurement; it is easy to be operated and it is suitable to be used at the determination field.
