（China）YY 9830 Chowunikira Chokha cha Kjeldahl Nayitrogeni
Zinthu zomwe zili mu malonda:
1) Dongosolo lowongolera limagwiritsa ntchito chophimba chamitundu 7-inch, kusintha kwa Chitchaina ndi Chingerezi, kosavuta komanso kosavuta kugwiritsa ntchito
2) Kasamalidwe ka ufulu wa magawo atatu, zolemba zamagetsi, zilembo zamagetsi, ndi machitidwe ofunsira kutsata magwiridwe antchito amakwaniritsa zofunikira zovomerezeka za satifiketi
3) Dongosololi limazimitsa lokha pakatha mphindi 60 popanda kugwira ntchito, zomwe zimasunga mphamvu, chitetezo komanso kukhala otsimikiza
4)★ Zotsatira zowerengera zowerengera zokha komanso zosungira, kuwonetsa, kufunsa, kusindikiza, ndi ntchito zina za zinthu zodziyimira zokha
5)★ Gome la mafunso a protein coefficient lomangidwa mkati mwa chida kuti ogwiritsa ntchito azitha kufunsa, kufunsa ndi kutenga nawo mbali pakuwerengera dongosolo, pamene zotsatira za kusanthula kwa coefficient = 1 ndi "kuchuluka kwa nayitrogeni" pamene zotsatira za kusanthula kwa coefficient > 1 zimasinthidwa zokha kukhala "kuchuluka kwa mapuloteni" ndikuwonetsedwa, kusungidwa ndikusindikizidwa.
6) Nthawi yothira madzi imayikidwa momasuka kuyambira masekondi 10 mpaka masekondi 9990
7) Kusungira deta kumatha kufika 1 miliyoni kuti ogwiritsa ntchito akambirane
8) Dongosolo la nthunzi limapangidwa ndi chitsulo chosapanga dzimbiri cha 304, chotetezeka komanso chodalirika
9) Choziziritsiracho chimapangidwa ndi chitsulo chosapanga dzimbiri cha 304, chokhala ndi liwiro lozizira mwachangu komanso deta yokhazikika yosanthula
10) Njira yotetezera kutayikira kwa madzi kuti zitsimikizire chitetezo cha ogwira ntchito
11) Chitetezo cha chitseko ndi chitetezo cha alamu kuti zitsimikizire chitetezo cha munthu
12) Kusowa kwa chitetezo cha chubu chochotsera mpweya kumalepheretsa ma reagents ndi nthunzi kuvulaza anthu
13) Alamu yosowa madzi mu dongosolo la nthunzi, imani kuti mupewe ngozi
14) Alamu ya kutentha kwambiri ya mphika wa nthunzi, imani kuti mupewe ngozi
