PHS-W series Microprocessor pH/mV Meter

PHS-W series Microprocessor pH/mV meter include the PHS-25CW, 3CW, 3BW. The meters are used to measure acidity and alkalinity of liquids.

Two Points Push-Button Calibration:PHS-W series with two points calibration function, it will prompt pH calibration solution when you calibrate the meter. You need only immerse the pH electrode into

standard solution and press ENTER key, then the meter will be calibrated automatically.

Auto-Buffer Recognition:In calibration, the meter will display ERROR if you use pH standard solution by mistake or not by the calibration prompt.

Viewing of Electrode Slope:After calibration, the meter will indicate electrode slope,

you can judge by the indicator to replace electrode or not.

Automatic Temperature Compensation:PHS-3BW with temperature sensor, which can measure temperature of solution and can automatic temperature compensation.

Keypad and Electrode Holder:The meter with waterproof panel, it's user can not worry for the sample solution splashing over the meter. The electrode holder can be used conveniently.
