NP-1806 Water Plant pH Monitor Introduction: The industrial online pH detector NP-1806 is a new generation intelligent water quality detector independently developed by our company. Featuring Chinese menu operation, high stability, excellent repeatability, and versatility, it can accurately measure the pH/ORP and temperature values in solutions. Widely used in wastewater treatment, purified water, circulating water, boiler water and other systems, as well as in the fields of electronics, aquaculture, food, printing and dyeing, electroplating, pharmaceuticals, fermentation, chemical and other process areas, PH/ORP value online detection. It has powerful functions in environmental monitoring and remote system applications such as surface water and pollution source discharge. Features: 1. The brand new waterproof, dustproof, and moisture-proof high-quality shell (IP65) technology, surface painting technology, and instrument appearance are elegant and high-end. 2. The product has high precision, high stability, and strong anti-interference ability. 3. Large screen dot matrix LCD display, support for Chinese and English menus (mutual switching), and simultaneous display of multiple parameters: PH/ORP values, temperature, output current, alarm points, etc. are displayed simultaneously, making it intuitive and easy to read. 4. Automatic temperature compensation function, which can manually correct pH and temperature values. 5. Communication function: Interface optoelectronic isolation technology, with RS-485 communication interface (MODBUS protocol partially compatible) (optional), convertible to RS-232. Two 4-20 mA circuits correspond to temperature and pH values, respectively. The pH value corresponding to the 4-20 mA current output can be arbitrarily set, and the 4-20 mA can be controlled in both positive and negative directions; The other 4-20 mA current output defaults to 0-130 ℃. Support internal IoT of the company and customized IoT of customers. 6. Automatic cleaning function, the cleaning device (optional) adopts tap water cleaning method. 7. Optional configuration of our company's upper computer online collection software for data collection and processing. 8. Notepad: It can store 50 pH measurement data and 40 ORP data, and users can record measurement data as needed. 9. Historical curve: capable of recording 50 sets of PH historical data and 40 sets of ORP data (sampling interval 1-240 minutes), and with query function. 10. Automatically recognize standard solution and can restore factory settings. 11. Watchdog function: Ensure that the instrument panel does not crash. 12. Power failure protection>10 years.
