PHS-2F Tus Nqi Zoo Tshaj Plaws Tshaj Plaws pH Meter

PHS-2F Benchtop pH Meter

Taw qhia

Nco ntsoov cov teeb meem hauv qab no thaum siv:

l Xyuas kom muaj av zoo.

l Tiv thaiv corrosive gas ntxeem tau.

l Khaws lub ntsuas ntsuas kom huv, qhuav, thiab tsis txhob sib cuag nrog kua qaub, alkali, ntsev tov.

l Cov cuab yeej no muaj rau kev siv sijhawm ntev -. Tom qab kuaj cov qauv, cov electrode yuav tsum tau muab tso rau hauv DI dej.

l  Keep the instrument interface clean, dry, and avoid contact with acid, alkali, salt solution. Insert short circuit when the instrument is not in use to avoid open circuit damage.

Cov ntsiab lus

pH nqes hav: Qhov muaj peev xwm hloov pauv rau txhua qhov kev hloov pauv pH, feem ntau qhia tias mV / pH lossis feem pua.

pH E0: Also called "zero potential", usually refers to the potential value of the pH=7.

pH ib -point calibration: Calibrate nrog ib tug pH buffer tov.

pH multi-point calibration: Calibrate nrog ob los yog ntau tshaj pH buffer tov.

Nta

l Txais cov qauv tsim tshiab, loj LCD segmented zaub.

l Nws yog tsuas yog siv los ntsuas pH tus nqi thiab muaj peev xwm tus nqi (mV) ntawm kev daws dej hauv thaj chaw tshawb fawb, kev lag luam, mining lag luam, tsev kawm qib siab thiab tsev kawm qib siab. Tsis tas li ntawd, nws tseem tuaj yeem ntsuas qhov muaj peev xwm electrode thaum sib txuam nrog ion xaiv electrode
