The industrial online ORP meter has the characteristics of full Chinese display, Chinese menu operation, full intelligence, multifunctionality, high measurement performance, and strong environmental adaptability. It can accurately measure the pH value and temperature of solutions. 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.

Performance characteristics of industrial online ORP meter:

1. Chinese LCD display, Chinese menu style operation, Chinese note taking.  

2. Microcomputer based: Using high-performance CPU chips, high-precision AD conversion technology, and SMT surface mount technology, it completes multi parameter measurement compensation, instrument self checking, with high accuracy and good repeatability.

3. High reliability: Single board structure, touch sensitive buttons, no switch knob or potentiometer.

4. Waterproof and dustproof design: protection level IP65, suitable for outdoor use.

5. Electromagnetic compatibility EMC/RFI design: Designed and manufactured according to European standard EN50081/50082.

6. Realize 25 ℃ conversion: Nernst electrode slope temperature compensation, pure water and ammonia added ultrapure water conversion at 25 ℃.

7. Dual high resistance input circuit: low internal resistance PH electrode, good instrument stability, fast response, strong anti-interference.

8. Solution ground connection: eliminate ground circuit interference.

9. Electrode diagnosis: Multiple calibration methods, E0 and S queries, monitoring electrode performance.

10. Automatic alarm function: Alarm signal isolation output, alarm upper and lower limits can be set arbitrarily, alarm hysteresis cancellation.

11. 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; The hysteresis can be adjusted within a range of 0-7.00pH.
