Orilon PHS-25C digital acidity meter is a laboratory digital acidity meter designed with a desktop structure. It displays the test acidity value through a liquid crystal digital display. The measured pH range is 0~14pH. The PHS-25C digital acidity meter has a light blue panel, light gray appearance, and knob-type operation. It has three operating knobs: positioning, temperature compensation, and slope. The operation is simple.
1. PHS-25C digital acidity meter is a precision digital acidity meter with digital display mode;
2. Two-point calibration method;
3. Each PHS-25C digital acidity meter is equipped with E201-9 composite electrode, which is the key measurement component of the pH meter and is used to measure the pH value of the hydrogen ion concentration in the aqueous solution.
The PHS-25C digital acidity meter can be used in laboratories to accurately detect the acidity of solutions, and can be used in environmental protection, sewage treatment, scientific research, pharmaceuticals, fermentation, chemical industry and other fields.
