QIWEI PHB-4 pH Tester, Portable Microcomputer 0~14pH

PHB-4

pH meter (portable microcomputer)

Overview

Qi WeiPHB-4 The ph Tester is a portable microcomputer pH meter, controlled by a microprocessor, with a measurement accuracy of 0.01 pH.The PHB-4 PH meter is equipped with E201-C-W molded case PH triple composite electrode or 018 temperature electrode, and the PH meter can perform automatic temperature compensation PH test.The PHB-4 PH meter is equipped with high-quality imported integrated components, which is accurate, stable and reliable, simple and convenient to operate, and is suitable for laboratory measurement of pH and mV value of solutions.

Application

PHB-4 ph Tester can be used in light industry, chemical industry, food, environmental protection, and education and scientific research departments.

Measurement method

1. Measurement of pH value

1) Measure the temperature of the solution with a thermometer first (PHB-4 contains a temperature electrode that can automatically detect the temperature);

2) Press the increase button ∧or decrease button∨ adjust the temperature value of the instrument accurately;

3) WASH THE ELECTRODE OF THE PH METER AND PUT IT INTO THE SOLUTION, STIR IT SLIGHTLY, PLACE IT STILL, AND READ IT WHEN THE MEASURED VALUE IS STABLE, AND THE OBTAINED READING IS THE PH VALUE.

2. Measurement of mV value

1) Switch the PH meter to the "mV" setting first.

2) Connect the ORP electrode or ion electrode (sold separately) and insert it into the solution to be measured.When the measured value is stable, the resulting reading is the ORP value or the potential value of the ion electrode.

pH Tester calibration options

Qi WeiPHB-4 pH TesterThe built-in intelligent chip can be used for one-, two-point or three-point automatic calibration. There are three cases: If the measurement accuracy ≤ 0.1 pH, only pH is used If the measurement range is only in the acidic range (≤7pH), you can choose pH7 and pH4 calibration, if the measurement range is only in the alkaline range (≥7pH), you can choose pH7 and pH10 calibration, if the measurement range is relatively wide, or when the pH electrode is used for a long time and there is aging phenomenon, you should choose three-point calibration, which will make the measurement accuracy higherPHB-4 pH TesterThe slope is adjusted to be consistent with the pH sensor.
