Hauv kev lag luam metallurgical thiab cov ntaub ntawv, hardness testers yog siv los ntsuas qhov hardness ntawm steel (carbon steel, alloy steel, stainless hlau) thiab tsis yog -ferrous hlau alloys (aluminium, tooj liab alloys) rau kev tswj kom zoo thiab kev ua kom zoo dua. Hauv kev tsim thiab kev lag luam kev lag luam, hardness testers yog siv los ntsuas qhov hardness ntawm cov khoom xws li lub zog, bearings, thiab bolts kom ua raws li cov kev cai tsim, thiab sim cov hardness ntawm raw cov ntaub ntawv los qhia cov txheej txheem ua. Rau cov workpieces hnyav thiab nyob rau hauv - qhov chaw kuaj, portable Leeb hardness testers yog haum rau ceev ceev ntawm - site hardness kuaj ntawm immobile workpieces xws li ntsia machinery, pwm loj, siab hlab ntsha, chav turbine generators, tshuab cuab tam guideways, thiab loj forgings/castings. Nyob rau hauv lub zog thiab petrochemical kev lag luam, hardness testers yog siv rau hardness kuaj thiab tsis ua hauj lwm tsom xam ntawm cov khoom Cheebtsam xws li fais fab nroj tsuag boilers, chav turbines, roj laum kav, roj kav, thiab li qub. Hauv kev lag luam automotive, hardness testers yog siv los ntsuas qhov hardness ntawm cov khoom siv tsheb xws li cav, kis, thiab chassis. Kev lag luam kws tshuaj siv cov ntsiav tshuaj hardness testers los ntsuas qhov tawv ntawm cov ntsiav tshuaj kom ntseeg tau tias lawv cov molding zoo thiab kev ua haujlwm tsis zoo. Hauv kev lag luam txheej thiab kev kho deg, mem hluav hardness testers yog siv los ntsuas qhov nyuaj ntawm cov xim zaj duab xis, coatings, thiab cov vaj huam sib luag zoo nkauj. Hardness testers kuj tseem siv rau hauv cov ntaub ntawv tshawb fawb thiab kev qhia kev sim hauv cov kev kawm loj hauv tsev kawm qib siab thiab tsev kawm qib siab. Tsis tas li ntawd, siab -precision, miniaturized portable hardness testers yog siv los ntawm NASA, Boeing, Airbus thiab lwm lub koom haum nyob rau hauv aerospace teb rau tsis yog - kuaj kev puas tsuaj.
