Detailed explanationOnline pH meterMain Features
The online pH meter simplifies its functions while ensuring performance, thus having a particularly strong price advantage. Clear display, easy operation, and excellent testing performance make it highly cost-effective. It can be widely used for continuous monitoring of pH values in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.
Main features of online pH meter:
1. 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.
2. High reliability: There are no complex function switches or adjustment knobs.
3. 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.
4. Automatic alarm function: Alarm signal isolation output, alarm upper and lower limits can be set arbitrarily, alarm hysteresis cancellation.
5. Industrial control watchdog: Ensure that the instrument does not freeze.
6. 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.
7. 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.
8. Automatic identification of incorrect calibration: If the user uses standard buffer solution incorrectly during calibration, the instrument will automatically prompt.
