Ukukhethwa okulungile kwamathuluzi okucindezela ngokuyinhloko kufaka phakathi ukucacisa uhlobo, ububanzi, ububanzi, ukunemba nokuzwela kwethuluzi, ubukhulu bangaphandle, nokuthi ingabe ukudlulisela kude kuyadingeka kanye neminye imisebenzi, efana nenkomba, ukurekhoda, ukulungisa, ne-alamu.
Isisekelo esiyinhloko sokukhethwa kwezinsimbi zokucindezela:
1. Izidingo zokulinganisa enqubweni yokukhiqiza, okuhlanganisa ububanzi nokunemba.Esimeni sokuhlolwa okumile (noma ukushintsha kancane), inani eliphezulu lokucindezela okukaliwe lizoba izingxenye ezimbili kwezintathu zevelu yesikali esigcwele segeji yokucindezela;esimweni sokucindezela (okuguquguqukayo) okuguquguqukayo, inani eliphezulu lengcindezi elinganisiwe lizokhethwa Ingxenye eyodwa yenani lesikali esigcwele segeji yokucindezela.
Amazinga okunemba wamathuluzi okuthola ingcindezi evamile ngu-0.05, 0.1, 0.25, 0.4, 1.0, 1.5 kanye no-2.5, okufanele akhethwe ezidingweni zokunemba kanye nombono wenqubo yokukhiqiza.Iphutha elikhulu elivunyelwe lethuluzi liwumkhiqizo webanga legeji yokucindezela kanye nephesenti lebanga lokunemba.Uma inani lephutha lidlula ukunemba okudingekayo ngenqubo, igeji yokucindezela enokunemba okuphezulu idinga ukushintshwa.
2. Izici zendlela elinganisiwe, njengezwe (igesi, uketshezi), izinga lokushisa, i-viscosity, ukugqwala, izinga lokunukubezeka, ukuvutha nokuqhuma, njll. Njengemitha ye-oxygen, imitha ye-acetylene, enophawu “olungenawo uwoyela”, ukugqwala- Igeji yokucindezela eqinile ye-medium ekhethekile, igeji yengcindezi ephezulu yokushisa, i-diaphragm pressure gauge, njll.
3. Izimo zemvelo zasendaweni, njengezinga lokushisa elizungezile, ukugqwala, ukudlidliza, umswakama, njll. Ezifana namageji wokucindezela okumelana nokushaqeka kwezimo zendawo ezidlidlizayo.
4. Ifanele ukubhekwa kwabasebenzi.Khetha amathuluzi anobubanzi obuhlukene (ubukhulu bangaphandle) ngokuya ngendawo yethuluzi lokubona kanye nezimo zokukhanyisa
