PHS-W series Microprocessor pH/mV meter, PHS-25CW, 3CW, 3BW. The meters are used to measure acidity and alkalinity of liquids.
Auto-Buffer Recognition:
In calibration, the meter will display ERROR if you use pH standard solution by mistake or not by the calibration prompt.
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.
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.
