PHS-2F Benchtop pH Meter
Introduction
Note following problems when using:
l Ensure a good grounding.
l Prevent corrosive gas invasion.
l Keep the instrument interface clean, dry, and avoid contact with acid, alkali, salt solution.
l This instrument is available for long-term stable usage. After test samples, the electrode should be immersed in DI water.
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.
Terms
pH slope: The potential variation for each pH change, usually expressed as mV/pH or %.
pH E0: Also called "zero potential", usually refers to the potential value of the pH=7.
pH one-point calibration: Calibrate with one pH buffer solution.
pH multi-point calibration: Calibrate with two or more pH buffer solution.
Features
l Adopt new design appearance, big LCD segmented display.
l It is mainly used to measure the pH value and potential value (mV) of water solution in the field of research institute, industrial, mining enterprises, universities and colleges. Besides, It can also measure electrode potential when matched with ion selected electrode
