Introduction to PHB-2 pH meter

PHB-2 ph acidity meter is a portable digital display PH meter. It is connected to an external PH electrode for testing. It has positioning and slope indicator lights. It undoubtedly provides users with convenience in indicating the status of the test process. It has a small-volume structure and is portable. More convenient. The PHB-2 pH meter has a simple appearance design, and the electrode interface is made of stainless steel, which has good corrosion resistance.

PHB-2 ph acidity meter has a liquid crystal display. The portable acidity meter is small in size and easy to carry. It is very suitable for on-site testing in experimental sites, assembly lines, sewage treatment, aquaculture and other occasions. It adopts E201 type composite electrode, which has the characteristics of fast response, high precision, good stability and easy replacement. The measurement accuracy of PHB-2ph acidity meter is ±0.02pH. In addition, the temperature will cause errors in the pH value measurement results, so the manual temperature compensation function of the PHB-2 portable pH acidity meter makes the user's measurement more accurate.

troubleshooting

1) The LCD has no display: Check the power supply part and switch to rule out disconnection, desoldering, poor contact, etc.

2) The digital display is unstable and beats constantly; check whether there are bubbles in the electrode bulb, whether the electrode interface is contaminated or damp, and whether there is poor contact between the electrode and the instrument, etc.

3) Slow data response: It is caused by aging and failure of the electrode. Use 3.3mol/Lkcl (potassium chloride) solution to activate the electrode for more than 4 hours. If the response is still slow, please replace the electrode. Insufficient Voltage (see LOBAT display) and whether there is any stirring.
