YOKE PHS-3C is a digital acidity meter, mainly used for the measurement of pH value and mV value of solutions. The instrument adopts LED or LCD digital display, has manual temperature compensation function, supports one or two point calibrating, and is equipped with E-201-C pH Composite Electrode or Three-in-One Electrode, suitable for acid alkalinity measurement in laboratories and other occasions.
1. Adopt 3 1/2-digit LED or LCD digital display for clear and intuitive readings. 2. With manual temperature compensation function, it can be compensated within the range of 0~ 99 ° C to improve measurement accuracy. 3. Support one or two point Calibration method, calibrating flexible and convenient. 4. Equipped with E-201-C pH Composite Electrode or Three-in-One Electrode, the measurement is stable and reliable.
The PHS-3C digital acidity meter works based on the principle of potentiometry. The instrument senses the activity of hydrogen ions in the solution through a pH composite Electrode (usually containing Glass Indicator Electrode and Reference Electrode), generating a corresponding potential difference (mV signal). This potential difference is proportional to the pH value of the solution. A high-input Impedance circuit (not less than 1 × 10 ^ 12 Ω) inside the instrument detects this weak signal. After amplification, temperature compensation and analog-to-digital conversion, the pH value or mV value is finally displayed in digital form.

Instrument level: 0.01 level
1. Preparation: Connect the pH Compound Electrode or 3-in-1 Electrode to the instrument host. 2. calibrate: According to the measurement accuracy requirements, select one or two point calibrate mode, use standard buffer solution to calibrate the instrument. 3. Temperature setting: According to the temperature of the tested solution, use the manual temperature compensation function to set the corresponding compensation temperature value. 4 measurement: Electrode is washed with deionized water and sucked dry with filter paper, immersed in the solution to be tested, and the pH value or mV value is recorded after the reading is stable. 5. Cleaning and storage: After the measurement is completed, clean the Electrode and store it according to the specifications.
• Check the condition of the Electrode before use and ensure that the Electrode bubble and liquid junction are clean and unobstructed. • When calibrating the instrument, use a fresh and accurate standard buffer solution. • When performing manual temperature compensation, ensure that the set temperature value is consistent with the actual temperature of the solution. • When measuring different samples, thoroughly clean the Electrode to prevent cross-contamination. • The instrument should be stored in a drying, non-corrosive gas environment. • When not in use for a long time, it should be stored according to the requirements of Electrode instructions. • Do not use in high Impedance or strong electromagnetic interference environment, so as not to affect the Measurement accuracy.
