PHS-3BW(PHS-3CT) Precision acidity meterDetailed product description：

PHS-3BW (PHS-3CT) precision acidity meter is designed digitally

The instrument is equipped with a high-performance CPU chip and all electronic components are soldered using surface mount technology, ensuring precision and reliability. The highly integrated circuit design reduces internal wiring, improves measurement accuracy and repeatability, and enhances anti-interference performance.

auto-calibration
The PHS-W series adopts a two-point button automatic calibration, and the display screen has a standard buffer prompt during calibration. You only need to place the electrode sensor in the solution according to the screen prompt and press the calibration button, and the instrument will automatically calibrate.

Automatically identify standard buffer solutions
During calibration, if the user mistakenly uses standard buffer or uses a standard buffer that does not match the instrument prompt, the instrument will automatically sound an alarm. The PHS-W series has a feature that avoids calibration errors caused by users using standard buffer solutions incorrectly or using spoiled standard buffer solutions

Automatic electrode slope and status display
After calibration, the instrument automatically displays the electrode slope and makes a judgment on the quality of the electrodes. If the electrode gradually ages, the electrode icon on the display screen will display accordingly, and users can determine whether to replace the electrode based on the icon.

Automatic temperature compensation
PHS-3BW is equipped with a temperature sensor that can measure the temperature of the solution in real time. When used with composite electrodes, the instrument can automatically compensate for temperature and display the measured temperature value

LCD (Liquid Crystal Display)
The instrument adopts a customized LCD display screen, which is simple and bright. It not only displays measurement values clearly, but also has operation status icons, allowing you to have a quick understanding of the instrument's condition.

Waterproof keyboard and electrode holder
The PHS-W series is equipped with waterproof panels that are resistant to acid and alkali, so users do not have to worry about damaging the instrument due to the sample solution falling on it.
