The Pin Brinell Testers provides portability, accuracy and ease of use.. all at one low price

    • Less operator influence on test results Onlyone optical measurement needs to be made. Consistent load regardless ofoperator technique. Can be as accurate as bench brinell testing
    • Easier to use Each pin works in the entirehardness range HB100-730. Easier to test in confined areas. Only oneimpression needs to be measured. The Impact model is smaller and easier touse on large parts. The Static C-clamp model is easier to use on small orthin parts
    • Test impressions can be re-measured without retesting
    • Faster operation One impression - one measurement.No additional computation required
    • Portable and inexpensive to use So portablethe Impact model fits in your pocket. Costs much less to purchase. Loweroperation cost
    • Accuracy equivalent to bench model Brinell testers
    • Impact model requires no clamping
    • Fewer moving parts
    • Small and lightweight
    • No messy oil
    • No need for recalibration

Unique Test Method

The portable Pin Brinell hardness tester is compact, versatile and economical to use. It provides accurate, low cost brinell hardness tests for field or shop applications and is often used as a back up for standard brinell hardness testers. Between the CPIT and CPST model, virtually any size and shape part can be tested in a wide range of hardnesses (HBW100 – HBW730. Because of its unique simplicity, the Pin Brinell Tester is easy to operate and very affordable.

The Pin Brinell uses a unique method for the application of the test load. Force is applied to the indenter by means of either a hammer blow (Model CPIT Impact Load Tester) or through the C-clamp (Model CPST Static Load Tester).

In either case, the force applied to the indenter is controlled by means of a calibrated expendable shear pin. The shear pin is placed against the flat end of the indenter and prevents it from receding into the indenter cavity as force is applied. When the force applied reaches the shear strength of the pin, the shear pin breaks (see illustration), relieving the load on the indenter.

The diameter of the resulting indentation is measured by means of a conventional Brinell microscope, and the associated hardness value for that measurement is read from the table that comes with the pins.
