PHS-3B/3C/2C/25 acidity meterStandard ConfigurationOne pHS-XX secondary meter, one HT5 power supply, one T226 composite electrode, one T22 temperature electrode (only available for pHS-3B), one set of electrode holder, and one set of standard buffer solution.

PHS-3B/3C/2C/25 acidity meterMain Features
Double row digital tube: displays pH value/mV and temperature value respectively.
Microcomputerization: Using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology, it completes multi parameter measurement, temperature compensation, instrument self-test, high accuracy, and good repeatability.
High reliability: Single board structure, touch sensitive buttons, no switch knob.
25 ℃ conversion: Nernst electrode slope temperature compensation, conversion for pure water and ammonia added ultrapure water at 25 ℃.
Input impedance>10¹²Oh.
Waterproof and anti-corrosion design.
Automatic conversion of standard solution temperature: The temperature curve of the standard solution is pre stored, and the pH value of the standard solution at the set temperature is automatically converted during calibration.
Automatic identification of incorrect calibration: If the user uses standard buffer solution incorrectly during calibration, the instrument will automatically prompt.
Network function: RS232 bidirectional communication, compatible with printer or TLab1.0 communication and data processing software.
Industrial control watchdog: ensures instruments do not crash
Automatically prompt measurement endpoint

The main differences among the four models are: 1. Different accuracies. 2. pHS-3C, pHS-2C, and pHS-25. Temperature compensation can only be manually inputted. 3. pHS-2C and pHS-25 are displayed on a single row digital display
