Mashandisirwo:
Yakanyanya kukodzera zvinhu zvichena uye zviri pedyo nechena kana kuyerwa kwehupfu pamusoro pechiso. Kukosha kwehuchena kunoenderana nekunzwa kwekuona kunogona kuwanikwa nemazvo. Chishandiso ichi chinogona kushandiswa zvakanyanya mukudhinda nekudhaya machira, pendi nependi, zvinhu zvekuvaka zvemakemikari, bepa nemakadhibhodhi, zvigadzirwa zvepurasitiki, simende chena, ceramics, enamel, ivhu reChina, talc, starch, furawa, munyu, sipo, zvizoro nezvimwe zvinhu zvekuyera huchena.
Wmusimboti wekushanda:
Chishandiso ichi chinoshandisa musimboti wekushandura kwemagetsi (photoelectric conversion principle) uye dunhu rekushandura reanalog-digital kuti rione kukosha kwesimba rekupenya kunoratidzwa nepamusoro pemuenzaniso, kuburikidza nekuwedzera masaini, kushandura A/D, kugadzirisa data, uye pakupedzisira kuratidza kukosha kwekuchena kwakakodzera.
Hunhu hunoshanda:
1. Ac, DC magetsi, magadzirirwo emagetsi mashoma, dhizaini diki uye yakanaka yechimiro, zviri nyore kushandisa mumunda kana murabhoritari (portable whiteness meter).
2. Yakashongedzerwa nechiratidzo chemagetsi mashoma, kudzima otomatiki uye dunhu risingashandise simba zvakanyanya, izvo zvinogona kuwedzera nguva yebasa rebhatiri zvinobudirira (push-type whiteness meter).
3. Kushandisa LCD LCD display yakakura ine hunyanzvi hwepamusoro, ine kuverenga kwakanaka, uye isingakanganiswi nechiedza chechisikigo. 4, kushandiswa kwe low drift high-precision integrated circuit, chiedza chinoshanda kwenguva refu, kunogona kunyatsoita kuti chishandiso chishande zvakanaka kwenguva refu.
5. Dhizaini yenzira inonzwisisika uye iri nyore yemaziso inogona kunyatsoona kuti kukosha kwakayerwa kwakarurama uye kunodzokororwa.
6. Kushanda kuri nyore, kunogona kuyera zvakajeka kupenya kwepepa.
7. Bhodhi renyika rekuongorora rinoshandiswa kutumira kukosha kwakajairika, uye chiyero chacho chakarurama uye chakavimbika.
