PHSB-260 portable acidity meter

●Overview

PHSB-260 portable pH meter is a digital display pH meter, double-row digital display liquid crystal, which can display pH temperature values at the same time. The instrument is suitable for the laboratory field sampling of universities, research institutes, environmental monitoring, industrial mining enterprises, etc. to measure the pH value potential (mV) of the aqueous solution, the ORP electrode can be used to measure the solution ORP (oxidation-reduction potential) )value. Coupled with ion selective electrode, the electrode potential value of the electrode can be measured.
