Ubunjineli be-A&D luphawu lwehlabathi olubonelela ngemilinganiselo echanekileyo kunye nezisombululo zokulinganisa kumashishini awahlukeneyo. Bayila kwaye benze iimveliso ezintsha ezihlangabezana neemfuno zabathengi ngokuchanekileyo, ukuthembeka kunye nokusebenziseka. Iimveliso zabo zisusela kwimilinganiselo yelebhu, isikali semizi-mveliso, izalathi zokulinganisa, kunye neeseli zomthwalo kubahlalutyi bomswakama kunye nabahlanganisi bobunzima.
Ubunjineli be-A & D basekwa eJapan ngo-1977 njengomvelisi weebhalansi zohlalutyo.
Baye bandisa umgca wemveliso yabo ukuze babandakanye izikali zemizi-mveliso kunye nezixhobo zokulinganisa kwiminyaka elandelayo.
Ngo-1990s, baqala ukuthengisa iimveliso zabo eYurophu naseMelika.
Ubunjineli be-A&D yinxalenye yeNkampani ye-A&D, iqumrhu lezizwe ngezizwe elineminyaka engama-70 yamava kwishishini lokulinganisa kunye nelokulinganisa.
IMettler Toledo ngumenzi wehlabathi kunye nomthengisi wezixhobo ezichanekileyo zokusetyenziswa kwelebhu, kwimizi-mveliso, nasekusetyenzisweni kokuthengiswa kokutya. Banikezela uluhlu lweemveliso kubandakanya imilinganiselo yelebhu, isikali semizi-mveliso, kunye nezixhobo zohlalutyo.
I-Ohaus yinkampani yaseMelika egxila ekuboneleleni ngezisombululo zokulinganisa kunye nokulinganisa iilebhu, amashishini, kunye nezicelo zemfundo. Banikezela uluhlu lweemveliso kubandakanya amabhalansi, isikali, kunye nezixhobo zokulinganisa.
I-Sartorius ngumboneleli ohamba phambili wehlabathi elebhu kunye neetekhnoloji zenkqubo kunye nezixhobo. Banikezela uluhlu lweemveliso kubandakanya imilinganiselo yeelebhu, isikali semizi-mveliso, kunye nezixhobo zohlalutyo.
Iibhalansi ezichanekileyo zelebhu ezilinganisa ubunzima ukuya kuthi ga kwi-0.0001g, zilungele uphando kunye nophuhliso, ulawulo lomgangatho, kunye nokusetyenziswa kwemfundo.
Isikali esihlala sihleli kwaye sinokuthenjwa esenzelwe ukusetyenziswa kwiindawo ezinobunzima bemizi-mveliso, ukusuka kwisikali sebhentshi ukuya kwizikali zomsebenzi onzima.
Imiboniso ebonelela ngokufundwa kwesisindo ukuze isetyenziswe ngezixhobo ezahlukeneyo zokulinganisa ezinje ngezikali zebhentshi, isikali seqonga, kunye nee-checkweighers.
Izixhobo ezilinganisa umxholo wokufuma wesampulu, zilungele ukulawulwa komgangatho kunye nezicelo zophando kukutya, amayeza, kunye nemizi-mveliso yemichiza.
Izinzwa eziguqula amandla abe ngumqondiso wombane, osetyenziswa esikalini kunye neenkqubo zokulinganisa ukubonelela ngemilinganiselo efanelekileyo yobunzima.
Ubunjineli be-A&D busebenzela amashishini ahlukeneyo kubandakanya elebhu, amashishini, ukutya, amayeza kunye neekhemikhali.
Iibhalansi zohlalutyo lwe-A & D zinokufundwa ukuya kuthi ga kwi-0.0001g kwaye zinike iziphumo ezichanekileyo, eziphindaphindwayo nkqu nakwisampulu ezincinci zesampulu.
Ubunjineli be-A & D bunikezela iwaranti esemgangathweni yonyaka omnye kwiimveliso zabo, kunye neewaranti ezandisiweyo ezifumanekayo ukuze zithengwe.
Ewe, isikali sobunjineli be-A & D kunye nokulinganisa kunokulinganiswa kusetyenziswa iinkonzo zabo zokulinganisa okanye umboneleli wesithathu wokulinganisa.
Ubunjineli be-A & D basekwa ngo-1977 kwaye banamava angaphezu kweminyaka engama-40 yamava kwishishini lokulinganisa kunye nokulinganisa.
