The HM300M host and probe adopt a streamlined design, an anti-interference aluminum alloy housing, a
high-strength scratch resistant glass panel, a high-speed computing MPU system, a 3.2 "high brightness
color LCD screen, and moneyless Bluetooth data printing and transmission technology. With a clear
human-computer interface, portable hardness measurement has been upgraded to the era of Industry 4.0.

Applications:
The HM300M electric ultrasonic hardness tester adopts a modular design, coupled with electric ultrasonic
probes MP-300 and UP-500. NP-800。The MP-1000 can measure the roller shaft. Screw, wind power, etc.
have chromium plating, copper plating, carburizing, nitriding layer hardness of the sample plating layer.
Product features:
High accuracy: the test accuracy can reach HV: ± 3% HV, HR: ± 1.5HR, HB: ± 3% HB;
Small indentation: The inner eye cannot be directly observed, and can only be detected using a high-power
full phase microscope;
Fast speed: The test results are output in 6 seconds, increasing the efficiency of the microhardness
tester by 20 times;
Large screen: The current measured value, maximum value, minimum value, average value, and hardness
conversion value are directly displayed on the 3.2 ″ color screen;
Easy to operate: You can quickly generate test results with just one click of operation;
Wireless printing: Support wireless Bluetooth printing and data transmission.
