DDS-11A irin lantarki conductivity mita
1.2 Kayan aiki Features
* Kayan aiki ya yi amfani da fasahar microprocessor, tare da ayyuka kamar daidaitawa ta atomatik da kariya ta kashe wutar lantarki;
* Kayan aiki tare da DJS-1C irin platinum baƙar fata lantarki (daidai 1.00);
* daidaitacce daidaitacce da kuma zafin jiki compensation coefficient;
* zafin jiki diyya za a iya ta atomatik ko manual;
* Light-taɓa maɓallin daidaitawa, kammala maye gurbin inji potentiator da band canzawa canzawa, sauki aiki.
* Kayan aiki ya yi amfani da double nuni aiki (0.56 'LED nuna gwada bayani conductivity, 0.36' nuna daidaitaccen darajar zafin jiki);
* Ma'auni ta atomatik canzawa, kai tsaye karanta ma'auni darajar, tare da cikakken ma'auni alama tips;
* Mai sauƙi da dacewa. Amfani da sabon kayan PC panel, kyakkyawan aminci.
