1. Isixhobo samkela i-5 "yokubonisa umzobo we-LCD kunye nomshicileli we-thermal wangaphandle njengesixhobo sokubonisa kunye nezixhobo zovavanyo olubonisa ngokulula iziphumo zovavanyo lwengxelo yengxelo kunye nokugcina;
2. Indlela yovavanyo ibonelela ngemowudi yeefotometer, i-waveleng yomxholo, uhlalutyo lobungakanani, indlela yokuhlalutywa kwenqanaba kunye nemowudi yovavanyo oluninzi, kwimodi yovavanyo oluninzi kunye nendawo yokuvavanywa ye-one kwaye igqitywe ngeendlela ezintathu eziqhelekileyo zokuhlalisa ;
3. Umsebenzi owodwa ohambelana naye unokuphelisa impazamo yomlinganiso obangelwe ngumsebenzi ohambelana nombala wombala (osebenza kuphela kwimowudi yefonti kunye nohlalutyo lobungakanani) ngokuzenzekelayo / umsebenzi opheleleyo;
4. Ukuchaneka okuthe kratya, ukuveliswa kwakhona kunye nokuzinza kwemilinganiselo yokufunda;
5. Imingxunya yovavanyo ezintathu, inokufunyanwa ngokuthe ngqo umxholo wefomati ye-qualdehyde.
