Product Description
Portable PH/Mv/Temp Meter (PH-221)
The meter are used to measure acidity and alkalinity of
Liquids.
Microprocessor-Based:
PH-221 has built-in high performance CPU, it can
Work about 200 hours continuously with 9 volt battery.
Two Points Push-Button Calibration:
The meter 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:
