Caliper

We are a Chinese caliper manufacturer, providing caliper Ф500-1200 and big diameter caliper for your option. Our caliper is a geological instrument used to determine the diameter of geological borehole and engineering borehole. The borehole diameter can be obtained by measuring and calculating the average value of bore diameter. The caliper is an auxiliary instrument for concrete pile detection system.

The borehole diameter curve measured can be applied in the following aspects:
1. To determine cement quantity used for well cementing.
2. To provide borehole diameter data for lateral curving logging and radioactive logging.
3. To find the position of wall collapse.
4. To select suitable fixed position of casing tube according to borehole diameter change.
5. To determine sectional surface of borehole.

Our calipers are made from high quality materials. They are widely used to determine the diameter of large diameter borehole in water conservancy, railway, road and bridge construction, and more. In addition, we also provide petroleum testing equipment, highway material testing instruments and bitumen testing equipment to satisfy all your demands. Furthermore, our location in Shanghai affords us convenient transportation, which lowers transportation costs for our customers.
We look forward to working with you! Please contact us for more information!
