BP-1Type concrete-like fill-level instrument from the Shandong Province Leling City Hammer Factory development and production, mainly used for core drilling method for testing the compressive strength of concrete in the process of concrete core-like face-level.

The product can ensure that the flatness of core samples after filling up to the "drill core method for testing the concrete compressive strength of technical regulations" (DBJ14-029-2004) To ensure that the two ends parallel to improve the core sample fill-up efficiency, to overcome the high-strength and small diameter concrete core fill-up flatness, the difficulty of vertical control difficult to improve the drill core method of measuring the compressive strength of concrete accuracy.

The product has a small size, easy to operate and so on.
