Portable Pen Digital Display Hardness Tester, High-Precision Hardness Tester,Multi Angle Measurement, Multi Hardness Scale, Long Battery Life (Ls252d)

（LS252D）D-type impact device is suitable for hardness measurement of ordinary metal parts （LS252DC） DC-type impact device is suitable for hardness measurement of short-sized, inner holes or narrow parts （LS252DL）DL-type impact device is suitable for hardness measurement of slender and narrow grooves, tooth or inner hole bottoms （LS252C）C-type impact device has small impact force and is suitable for hardness measurement of hardened layers and small or thin parts HOW TO USE Ⅰ Loading: Push the shock absorber from the bottom of the instrument to the locked position with the loading lever. Ⅱ Position: Hold the bottom of the instrument close to the object to be measured and hold it still. Ⅲ Measuring: Press the release button on the top of the instrument and measure the hardness of the object to be measured. PRODUCT SPECIFICATION Item type: Digital Richter hardness tester Hardness scale: HL, HV, HB, HS, HRA, HRB, HRC Measuring range: HLD (170-960), HV (83-976), HB (30-651), HRC (17.6-68.5), HS (26.4-99.5), HRB (13.5-100), HRA (60-85.8) ) Resolution: 1HL Measurement accuracy: ±6HL Repeatability: 6HL Display: 128x64 dot matrix LED Power supply: 1 x 3.7V rechargeable lithium battery 250mAh (built-in), over 5000 continuous measurements on a single full charge Charging interface: USB (Type C) Operating temperature range: -10°C to 50°C, 0-85% RH (non-condensing) Storage temperature range: -10°C to 60°C, 0-85%RH (non-condensing)

• 【Portable】Using a pen-type integrated design, ergonomically designed, compact and easy to carry. Built-in lithium battery, long-lasting battery life after full charge.
• 【Applicable Materials】Steel and cast steel, alloy tool steel, stainless steel, gray cast iron, nodular cast iron, cast aluminum alloy, copper zinc alloys (brass), an alloy of copper and tin, copper(bronze)
• 【Multi-angle measurement】It can measure 360 degrees. The probe has a built-in direction sensor, which will automatically compensate the measurement error of different impact directions to meet the measurement of different angles.
• 【Multiple hardness scales】The instrument has built-in multiple hardness scales, namely HL, HV, HB, HS, HRA, HRB, and HRC, which can be switched freely, without calculation, and directly output data.
• 【High precision】The impact body is made of carbide material with ultra-high hardness. It adopts advanced double-coil design and store 9 sets of data. It has good repeatability and high measurement accuracy.
