Granite chinhu chinoshandisika uye chinogara kwenguva refu chave chichishandiswa kwemazana emakore mumabasa akasiyana-siyana, kubva pakuvaka kusvika pakuveza. Simba rayo rechisikigo uye kuramba kwayo kupfeka zvinoita kuti ive yakakodzera zvikamu zvakanyatsonaka mukushandiswa kwemetrology.
Zvikamu zvegranite zvakanyatsonaka zviri kushandiswa zvakanyanya mukushandiswa kwemetrology nekuda kwekugadzikana kwazvo uye kururama kwazvo. Granite ine low thermal expansion coefficient uye high rigidity zvinoita kuti ive chinhu chakanaka chekugadzira maturusi ekuyera akarurama akadai semapuratifomu, ma angle plates nema ruler. Zvikamu izvi zvinopa hwaro hwakasimba uye hwakavimbika hwezvishandiso zvekuyera, zvichiita kuti pave nemhedzisiro chaiyo uye inodzokororwa.
Chimwe chezvakanakira zvikuru zvekushandisa zvikamu zvegranite zvine hungwaru mukushandiswa kwemetrology kugona kwadzo kuchengetedza kugadzikana kwehukuru nekufamba kwenguva. Kusiyana nezvimwe zvinhu, granite haichinji kana kukanganisika nyore nyore, zvichiita kuti zviyero zvirambe zvakafanana uye zvakavimbika. Izvi zvakakosha zvikuru mumaindasitiri akadai sendege, mota nekugadzira, uko zviyero zvakanyatsonaka zvakakosha pakudzora mhando uye kutevedzera mitemo yeindasitiri.
Pamusoro pekugadzikana kwazvo, zvikamu zvegranite zvine hungwaru zvinopa hunhu hwakanaka hwekudzikisa vibration, izvo zvakakosha pakushandiswa kwemetrology sezvo kunyangwe kudedera kudiki kunogona kukanganisa kunyatsoyera. Izvi zvinoita kuti granite ive chinhu chakanakira kugadzira puratifomu yekuyera yakagadzikana uye yakavimbika, ichiva nechokwadi chekuti kuyerwa hakukanganisirwi nezvinhu zvekunze.
Pamusoro pezvo, kuvimbika kwechisikigo kwegranite pakuora nekusakara kunoita kuti ive sarudzo yakasimba uye isingadhuri pakushandisa pakuyera. Kugara kwayo kwenguva refu kunoita kuti zvikamu zvakagadzirwa negranite zvigone kumira zvakanyanya uye mamiriro ekunze akaoma pasina kukanganisa kururama kwayo.
Muchidimbu, zvikamu zvegranite zvine hungwaru zvakakodzera kushandiswa pakuongorora mafambiro emvura nekuda kwekugadzikana kwazvo, kururama, uye kugara kwenguva refu. Sezvo zvinodiwa pakuyera zvakarurama uye kuvimbika zvichiramba zvichiwedzera mumaindasitiri, kushandiswa kwegranite mukuongorora mafambiro emvura kunogona kuwedzera, zvichiwedzera kusimbisa mukurumbira wayo sechinhu chinosarudzwa pakugadzira mafambiro emvura.
