Lx251d Advanced Leeb Hardness Tester for Accurate Material Measurement¹

Preview:

Product DescriptionProduct DescriptionLX251D Leeb Hardness Tester The ability of a material to locally resist hard objects pressing into its surface is called hardness, which is an index to measure the softness and hardness of a material. Based on the principle of Leeb hardness measurement principle, LX251D Leeb Hardness Tester can detect the hardness of a variety of metal materials. It adopts advanced digital probe technology, and the digital signal processing is completed directly on the probe which means that the probe is not easy to be disturbed and provides excellent accuracy. The orientation sensors inside the probe will compensate the measurement errors in different impact directions automatically to ensure the accurate data. Providing a variety of hardness scales , such as Leeb scale (HL), Vickers scale (HV), Brinell scale (HB), Shore scale (HS), Rockwell scale (HRA/HRB/HRC), and they can make a mutual conversion to avoid cumbersome manual calculation. Besides the hardness, the instrument can measure the strength of the materials. The practical value of using LX251D Leeb Hardness Tester for hardness testing lies in its incomparable portable characteristics that bring users a perfect experience.SpecificationParametersValueProbeImpact device DHardness ScalesHL, HV, HB, HS, HRA, HRB, HRCMeasurement RangeHLD(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)Resolution1HLAccuracy±12 HL, ±6 HL typicalRepeatability6HL (factory standard)Display240 * 16 dot matrix LCDPower Supply2 AA alkaline dry batteriesHost Size142*72*28 mmProbe Size148*31*25 mmWeight247gWorking Temperature Range-10~50℃,0~85%RH(no condensation)Storage Temperature Range-10~60℃,0~85%RH(no condensation)FeaturesMulti-Angle Measurement with Automatic CompensationThanks to a built-in direction sensor, the probe can automatically adjust for measurement discrepancies caused by different impact angles—enabling accurate readings regardless of the testing position.Quality Control SupportUsers can set upper and lower limit thresholds to automatically determine whether materials meet predefined hardness standards—ideal for batch inspections.Advanced Digital Probe TechnologyThe device leverages advanced digital probes, processing signals directly within the probe. This setup reduces interference and delivers excellent testing accuracy.Multiple Hardness Scale ConversionThe tester supports and switches seamlessly between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), and Rockwell (HRA/HRB/HRC) scales. This eliminates the need for manual reference tables. It can also measure material strength, extending its functionality.High Precision, Certified AccuracyWith an accuracy of ±6HL, the LX251D meets the standards of China's national metrology institute, ensuring reliable and certified results.Statistical FunctionalityThe tester automatically calculates and displays the maximum, minimum, and average values of the latest 9 measurements.User Calibration SupportUsers can calibrate the device using standard parts to eliminate any potential measurement errors.CertificationsPackagingNo.Product NameQuantityUnit1Leeb Hardness Tester1Set2Standard Leeb Hardness Block1pcs3Nylon Brush1pcs4Small Support Ring1pcs5User Manual1pcs6Calibration Report1pcs7Certificate / Warranty Card1pcs8Plastic Case1pcsCompany ProfileShenzhen Lianxiang Instrument Equipment Co., Ltd.
