Product Introduction

1. Purpose and Characteristics

NJS-75S single brick in-situ double shear tester( in-situ single brick two horizontal mortar joint shear test instrument) is a specialized instrument used to test the shear strength of building masonry. This instrument is with a small hydraulic device that uses a piston to lift and push the cover plate to generate a force to test the shear strength of the masonry block, make the upper and lower surfaces of the block to shear. The shear strength of the masonry block is calculated by measuring the force at which the block shears. The test results are intuitive.

① The instrument has a novel structure, small size, light weight, and convenient operation.

② The manual pump is used to load the oil cylinder, which is easy to operate and has strong interchangeability.

③ The digital display pressure gauge can directly read the shear force.
