Economical pocket pH tester, 2 points calibration, Automatic Temperature Compensation. The meter is suitable for measuring the pH of liquids, accuracy: 0.01pH.



1) LH-PH10 16-bit, LH-PH20/30 32-bit MCU runs at high speed, and the test speed is fast;
2) Comply with domestic and foreign calibration standards; independently developed software and hardware; 0.01PH and 0.1°C/°F accuracy guarantee;
3) The whole series adopts laboratory-level sensors, which are comparable to non-universal sensors; high-quality electronic components and NTC material temperature probes are used to ensure measurement stability;
4) LH-PH20/30 has a buzzer reminder function to remind you when power on, the measured value is stable, the calibration is completed, and the button operation has a sound reminder;
5) AAA (No. 7) battery power supply, replacement is more convenient;
6) Full character display, clearer menus and clearer options (LH-PH20/30); high-contrast LCD multi-data display on the same screen, softer orange backlight, LH-PH30 supports professional adjustment of multi-color personalized backlight presentation.
