Point Load Tester

The Point Load Tester is a uniaxial compression testing instrument designed for reading out pressure when a specimen is broken, and it consists mainly of a main unit, a pressure gauge and a hydraulic pump.

It is very easy to carry the system and make measurements at a site because of its compact and lightweight design.

Also, it takes only a short time to carry out a test, and all the works can be done easily by one person.
