MH-500G is an advanced state-of-the-art palm sized metal hardness tester with many new features. It still used our dual-coil technology which makes MH-500G to have extraordinary accuracy: +/-2 HL (or 0.3% @HL800) with high contrast colour TFT display and durable metal housing. Equipped with impact device G. It has a moving bar-graph display which can evaluate the workpiece upon deviation value by different colour for easy visual distinguish. MH-500G can download measuring data to PC and printout to micro-printer by USB port and wirelessly with internal wireless module. The battery can be charged simply from USB port, also it has a customer re-calibration and statistics function.

SH-660 is an innovation of Leeb hardness tester, which based on the new technology - dual-coil sensor inside probe. All probes worked with SH-660 are modularized digital probe, which gives more accurate hardness value. Besides, SH-660 can also work with our wireless probe and new RP reading probe as optional.

SU-300M Motorized Ultrasonic Hardness Tester is a popular portable durometer made by Sinowon group. It applies method of ultrasonic contact independence to makehardness testing at the spot or in the laboratory. SU-300M is a perfect portable durometer for hardness testing about the coating and plating, it can measure the hardness of chrome, copper plating, carburized layer andNitriding layer effectively. SU-300M is a NDT durometer due to the contact indention is too small to observe, it is one of the excellent solution totest hardness of finished products, such as, the mold, gear, shaft, rod, screw, rails, etc. SU-300M can not only work with the motorized probes, but also work with the manual probes, which is able to meet the different application in light of different condition of surface roughness.
