characteristic

The host core adopts 32-bit computer, ARM system, CAN bus, and 5G mobile wireless data communication technology, which facilitates interconnection and interoperability with existing networks. Wherever there is a Chinese wireless communication network, it is easy to access the main data of the instrument panel and set alarms through 5G mobile phones. Realize high reliability, high precision, high speed, convenient management, and enable users to fully enjoy subsequent value-added services.

The full Chinese character menu displays multiple parameters on the same screen, with eight key positions for operation. Two key positions are backlight keys, with adjustable backlight for easy operation.

Separate back cover for easy installation and wiring.

Unique electrode cup structure facilitates the disassembly of electrodes, making measurement values more stable.

Data storage technology greatly increases the amount of data and can store tens of thousands of sets of measurement data, as well as 5000 system operation records (known as the 5000 notepad function).

1. There are two types: high purity water precision grade or ordinary water ordinary grade. The standard configuration is high purity water precision grade.

2. For short distances ≤ 20m or long distances of 20-10km (distance between electrodes and the host), our company uses a 32-bit front-end box and CAN bus for long distances. The standard configuration is a short distance of ≤ 20m.

3. Divided into pipeline type, sinking type, and lead out type (electrode cup type). Sinking is used for water tanks, extraction is used for sampling racks in thermal power plants, and pipeline is mainly used for coal chemical and metallurgical industries. The standard configuration is lead out (electrode cup type).

4. There are three types of high-purity water systems: dual composite electrodes, triple composite electrodes, and discrete electrodes. The standard configuration is three composite electrodes.

5. Divided into 5G communication mode or conventional communication mode (standard configuration is conventional communication mode).

Applied in thermal power plants, thermal power plants, petroleum, chemical industry, chemical fiber, metallurgy, environmental protection, papermaking, printing and dyeing, coal chemical industry, water management, food hygiene, etc
