PS-1701 la qaadan karome mitirwaa muuqaal dijital ahMe mitir, iyada oo leh shaashadda dijitaalka ee LCD, oo soo bandhigi karaPHiyo qiimayaasha heerkulka isku mar. Qalabka ayaa lagu dabaqayaa sheybaarka ee xarumaha jaaliyadaha dugsiga hoose, machadyada cilmi-baarista, la socodka deegaanka, kormeerka deegaanka iyo macdanta shirkadaha iyo waaxaha kale ama qayb ka mid ah qayb ka mid ah si loo go'aamiyo xalka aqueous 'PHQiimaha iyo qiimayaasha (MV). Ku qalabeysan korantada orp-ka, waxay cabiran kartaa xalka xalka OPP (awooda yareynta) qiimaha; Ku qalabeysan electrode-ka gaarka ah, waxay cabbiri kartaa korantada suulka korantada ee korantada.

Waa maxay ph?
PH waa cabir ku saabsan waxqabadka Hydrogen Ion ee xalka. Biyo saafi ah oo ay ku jiraan isku dheelitir isku mid ah ee iondrogen togan (h +) iyo
diidmo ahHydroxide ion (Oh -) waxay leedahay ph dhexdhexaad ah.
● Xal loo yeelo u fiirsashada sareeya ee iondrogen ion (h +) oo ka badan biyuhu saafiga ah waa aashito oo ay leeyihiin wax ka yar 7.
● Xal loo yeelo uruurinta sareysa ee hydroxide ion (oh -) inta biyuhu yihiin aasaaska (alkaline) oo ay leeyihiin ph ka weyn 7.
