Rockwell Hardness Tester NRHT-101

Rockwell Hardness Tester NRHT-101 is a fully automatic portable hardness tester ideal for determining the hardness of metals and their alloys. Designed with an advanced touchscreen to display dwell time values and test force. A microcontroller fit with an LED light and high-speed thermal printer allows you to print out test results quickly. It has an improved accuracy using its 0.05mm resolution.
