OP-SHB-3000E (Electronic Brinell Hardness Tester)
- OP-SHB-3000E adopts he load cell to replace the traditional weight, this innovative design makes the instrument more accurate.
- Selection of testing force and dwell time is controlled and monitored on then front panel, it is automatic during the process of loading, dwell and unloading.
- OP-SHB-3000E uses 20X Brinell measuring microscope to measure the diameter of indentation, then the operator traces the Brinell hardness table to get the testing result.
Description
Applications
- OP-SHB-3000E is an affordable electronic Brinell testing machine with high accuracy, reliability and durability, it is applied at the workshops and measurement departments for determining the Brinell hardness of the material of ferrous and non-ferrous metals.
