Portable Hardness Tester Features:

● Large LCD with back-light, showing all functions and parameters. Portable design, the size of the instrument is only 20cm.
● Test at any angle, even upside down.
● Wide measuring range. It can measure the hardness of all metallic materials. Direct display of hardness scales HRB, HRC, HV, HB,HS, HL and three types of strength values immediately.
● Large memory could store 100 groups (Relative to average times 32~1 ) information including single measured value, mean value,impact direction, impact times, material and hardness scale etc.
● Low power design with stable integrate circuit. Charging for three hours, it can use for two months.
● Integrate the high speed thermal printer into the instrument with which it supports immediately printing function. The long lasting paper can save the data permanently.
● Battery information showing the rest capacity of the battery and the charge status.
● Auto power off to save energy. It can work continuously for at least 150 hours without EL and printing.
