HST-L252D Pen Leeb Hardness Tester
HST-L252D Pen leeb hardness tester
The HST-L252D is a state-of-the-art, palm-sized metal hardness tester that combines both the impact device and controller in a single compact unit—small enough to fit in your pocket. Featuring the latest dual-coil technology, it delivers outstanding measurement accuracy (±6 HL) and repeatability (6 HL). The built-in orientation sensors automatically correct measurement errors caused by different impact directions, ensuring consistently accurate data. The tester also includes a durable metal housing and a bright OLED display. Equipped with a D-type impact device, theHST-L252D is ideal for a wide range of testing applications—from polished parts and heat-treated surfaces to situations requiring high test volume. It also features USB charging and supports user re-calibration.
