Feature:1. A Variety of Values: With high definition bright screen, one key conversion, one measurement can display 7 kinds of hardness values (HLD, HB, HV, HS, HRA, HRB, HRC).2. Multi-Function: Data saving function, easy to record and view. 10 minutes automatic shutdown function.3. High-Precision Measurement: Accurate measurement value, display value error 6% (HLD = 800), display value repeatability of 0.8%; can automatically calculate the average hardness value.4. Easy to Use: The hardness tester supports "Forged Steel" materials. When testing "Forged Steel" specimens with the D-type impact device, the HB value can be read directly, eliminating the need for manual tabulation.5. Wide Application: Widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other testing fields. Is the material non-destructive hardness testing professional necessary instrument.Specification:Specifications:Model: LS-200Material: ABSMeasuring Direction: Support 360º (vertical down, slant down, horizontal, slant up, vertical up)Measuring Range: (170-960)HLD, (17.9-69.5)HRC, (19-683)HB, (80-1042)HV, (30.6-102.6)HS, (59.1-88)HRA, (13.5-101.7)HRBHardness Unit: Richter (HLD), Brinell (HB), Rockwell B (HRB), Rockwell C (HRC), Rockwell A (HRA), Vickers (HV), Shaw (HS)Display Value Error: ±6% (HLD = 800)Display Value Repeatability: 0.8% (HLD = 800)Display: Industrial-grade 128 × 64 graphic dot matrix LCD liquid crystalPower Supply: 1800mAh rechargeable lithium batteryContinuous Working Time: About 20 hoursOperating Conditions: Operating temperature -10~50 Storage Temperature: -30~60 Relative Humidity: ≤ 90%Applicable Materials: Steel and cast steel, alloy tool steel, stainless steel, gray cast iron, ductile cast iron, cast aluminum alloy, copper-zinc alloy (brass), copper-tin alloy (bronze), pure copper, forged steelLanguage: Chinese and English optionalItem Size: 148 * 83 * 30mm / 5.82 * 3.26 * 1.18inItem Weight: 201g / 7.09ozPackage Weight: 636g / 22.43ozPackage Size: 23 * 19 * 5cm / 9.05 * 7.48 * 1.97inPackage List:Package List:1 * Digital Hardness Tester1 * D-Type Impact Device (1 set)1 * Support Ring1 * Cleaning brush1 * USB Cable1 * User Manual (English)
