PH meter

The tester consists of two parts: sensor and secondary meter. It can be equipped with three composite or two composite electrodes to meet various usage situations. Equipped with a pure water electrode, it can be used to measure the pH value of water with a conductivity less than 3 μs/cm (such as chemical feed water, saturated steam, condensed water, etc.).

Characteristics

● LCD display
● A variety of electrodes available
● Auto/manual temperature compensation
● Panel mounting, cabinet mounting, embedded installation
