    Tip: 1. This Leeb hardness tester does not contain calibration blocks, you need to purchase calibration blocks locally. Thank you for your patronage! 2.This instrument is equipped with D-type sensor, which needs to measure the hardness of metal more than 5mm. D-type probe is a conventional probe, which is suitable for measuring most workpieces. Workpieces of special materials need to be equipped with other types of probes. 3.The three needle thread of the sensor has two colors of yellow and gray. Two colors of the line with random sensors, random delivery. Thank you for your support! Product Features: *Compact plastic case,suitable for use under poor working conditions. 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 *Large screen (segment LCD), showing all functions and parameters. With EL background light. *Large capacity memory could store 100 groups information. *Datapro Software to connect with PC via USB port. *Software calibration function.
