S690QL matla a phahameng a tšepe poleiti

Ka lebaka la thepa ea tlhaho e matla haholo, ho sebelisa S690QL ho tla khothaletsa meaho e entsoeng ka mokhoa o bobebe e nang le bokhoni bo eketsehileng ba ho lefa le ho sebetsa hantle ha matla.
Lintlha tsa tekheniki tsa S690QL li hlalositsoe ka tlase.
S690QL - Tlhaloso ea Kereiti
Tlhaloso ea kereiti ea S690QL ke e latelang:
S = Tšepe ea Sebopeho
690 = bonyane ba matla a tlhahiso (MPa)
Q = Ho tima & ho halefisa
L = Mocheso o fokolang oa ho hlahloba boemo ba mocheso

S690QL - Sebopeho sa Lik'hemik'hale
Sebopeho sa lik'hemik'hale sa S690QL se fanoe tafoleng e ka tlase.
