Purpose

  The instrument is a new type inclination measuring instrument which adopts a high precision fiber optic gyroscope. It can be used to determine dip angle and azimuth angle of vertical borehole or direction borehole in magnetic field or iron casing tube. It can also determine the depth of borehole accurately. It has been widely used in engineering, hydrology, oil field, coal field, and geology for borehole determination.

I.Main technical features

1. It adopts a high precision fiber optic gyroscope as the measuring component. Small size and long lifetime. Good shock
    and vibration resistance. The zero drift is small.

2. It adopts a high precision double-shaft sensor to measure the dip angle. The dip angle data will be collected by 24 bit
    AD and processed.  

3. It is no need to do surface orientation. The true north azimuth angle can be measured at any time.

4. Equipped with special software, it can show test data table, and plot plane diagram, sectional diagram, side projection
    diagram, and space trace diagram.
