Digital Portable Hardness Tester


Digital Portable Hardness Tester
Spring-less impact device with auto-reload mechanism

With spring-less auto-reload mechanism, the user can repeatedly perform the test without manually loading the impact device. This force mechanism provides an easy hardness testing experience. It benefits from steady indentation energy for the entire device lifetime.

Digital Portable Hardness Tester
One-hand test experience

The impact device is automatically loaded after each test and does not need the user to manually load it with two hands after each test. It provides more flexibility for the user to perform the hardness testing on non-easily accessible surfaces.

Digital Portable Hardness Tester
High accuracy in electromagnetic-radiated environments

The impact device is designed with a very robust and accurate velocity measurement system by which very accurate hardness testing can be performed. This measuring system is accurate even in the environments where electromagnetic radiation is very high.

Digital Portable Hardness Tester
Software user calibration

The user can calibrate the device through the menu for each test material on three hardness ranges, i.e., low, medium, and high. This feature provides flexibility and accuracy for the user to calibrate the device based on a specific application.
