Purpose:

The instrument is newly developed device to determine slope of horizontal borehole. It adopts a high precision sensor of new type and computer techniques, so its performance is better than general inclination measurement instrument. It has been widely used to determine horizontal borehole in the non-magnetic area for geology engineering, construction, and detection activity in the mining, hydrology, railway, and construction department.

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 it is in high precision and good repeatability; it can upload test data to a laptop through RS232 serial port directly, so it can show test data, plane diagram, sectional diagram, and 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.
