HARDNESS

 State-of-the-art palm sized metal hardness tester which incorporates the impact device and controller into one unit. It easily fits in a pocket. It used lastest dual-coil technology which makes the tester to have extraordinary accuracy: ±6 HL and good repeatability:6HL. It adopts orientation sensors that will compensate the measurement errors in different impact directions automatically to ensure the accurate data, with durable metal housing and OLED display screen. Equipped with impact device D, LS252D is especially suitable for almost any object, polished parts and heat-treated surfaces or the situation requiring a large number of tests. The battery can be charged simply from USB port, also it has a customer re-calibration function. 

 The Webster hardness tester based on Webster hardness measurement principle, suitable for aluminium alloy, brass, copper, soft steel and other metal materials hardness measurement. It's particularly suitable for production, sales and construction site batch of metal profiles, plates, tubes, etc. to carry out rapid, non-destructive, piece-by-piece qualification inspection. The instrument adopts eddy current induction principle measurement technology, with good repeatability and measurement accuracy. It has a variety of built-in hardness systems, which can be converted between Webster (HWA), Rockwell (HRE), Rockwell (HRF), Rockwell (HRB), Vickers (HV) and Brinell (HB)
