PHS Series

PHS-W SERIES MICROPROCESSOR pH/mV METER   PHS-W series precision 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 [ CAL ] key, then the meter will be calibrated automatically.   Auto-Buffer Recognition: In calibration, the meter will display ERROR automatically if you use pH standard solution by mistake or not by the direction.   Viewing of Electrode Slope: After calibration, the meter will indicate electrode slope, you can judgment by the indicator to replace electrode or not.                 Automatic Temperature: PHS-3BW with temperature sensor, which can measure temperature of solution and can automatic temperature compensation.   Specifications:		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.   What's included: pH glass electrode, pH buffers, electrode holder, 9V power adapters, temperature probe (only for PHS-3BW)
