GDX-3A1 Digital Inclinometer




The instrument is latest developed digital inclination measurement instrument of new type with the function of manual test data recording. It is an upgraded products used to determine dip angle and azimuth angle of vertical borehole or directional borehole. It is the best instrument used to determine inclination of borehole, which is more than 54 mm in diameter, in the non-magnetic mining area, hydrology, oil field, coal field, and geology.


Main characteristics

1. It adopts a high precision gravity accelerator and a 3D magneto-resistance sensor to form the measurement system, so it is sensitive, good in repeatability, and small.

2. It uses modern digital signal processing techniques, so it can calculate dip angle and azimuth angle accurately, so that they can meet the requirement for accuracy.

3. It adopts long distance transmitting technology, so it can transmit digital signal through long cable reliably. This highly improves anti-interference ability of the instrument.

4. It removes hammer swing parts in the probe tube. This highly improves anti-shaking ability of the instrument. The depth interval and measurement point numbers can be preset at random. This improves measurement efficiency.

5. It adopts an ultra-brighten LCD for display, so it is convenient for use in the field.
