Main Features：

◇Microcomputerization: Using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology, it completes multi parameter measurement, temperature compensation, automatic range conversion, instrument self-test, with high accuracy and good repeatability.

◇High reliability: Without complex functional switches and adjustment knobs.

◇Strong anti-interference ability: The current output and alarm relay adopt photoelectric coupling isolation technology, which has strong anti-interference ability and enables remote transmission.

◇Automatic alarm function: Alarm signal isolation output, alarm upper and lower limits can be set arbitrarily, alarm lag cancellation

◇Industrial control watchdog: ensures instruments do not crash

◇Network function: isolated current output and RS485 communication interface; The upper and lower limits of the output corresponding to the pH value of the current can be set arbitrarily, and the hysteresis can be adjusted within a range of 0-7.00pH.

◇Automatic conversion of pH value of standard solution: 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.
