Purpose:
The instrument is a new and economical digital inclination measurement instrument with the function of automatic data recording. It is suitable to determine dip angle and azimuth angle of vertical or directional borehole in the non-magnetic area. It has been widely used to determine inclination of borehole, which is more than 40 mm in diameter, in the engineering, hydrology, oil field, coal field, and geology.
Main characteristics:
1. It adopts a high precision gravity accelerator and 3D magnetic resistance to form measurement system of the instrument, so it has high sensitivity, good repeatability and small volume.
2. It adopts modern digital signal processing techniques to accurately calculate dip angle and azimuth angle, so test data can meet requirements on precision.
3. It uses modern coded long distance transmission techniques of communication, so it can transmit digital signal through long cable reliably. This highly improves anti-interference ability of the instrument.
4. It does not use heavy hammer swing parts in the inclinometer probe, so this highly improves anti-shake performance of the instrument. Depth interval and quantity of measurement points can be preset at random.
5. It adopts an ultra-brighten LCD for display and uses 6 control buttons for man-machine conversation. Test can be saved automatically without manual intervention.
6. It combines button operation and display together, so it is convenient to be operated. If equipped with a micro-printer, it can print out test data at determination field.
