Introduction: HK-258 portable micro-dissolved oxygen analyzer adopts the splitter structure design of the transmitter (measurement part) and the controller (mobile phone APP). It has features such as high measurement accuracy, fast response speed, compact size, and easy operation; the user downloads it through the mobile phone. Dissolved oxygen APP as a controller, you can view and operate the equipment status, real-time data and historical data; mainly suitable for measuring the concentration of oxygen in aqueous solution, especially suitable for the detection of low concentration of dissolved oxygen in ultra-pure water, can be widely Applied in power, petrochemical, steel and many other industries. Features: 1. Polarographic micro-dissolved oxygen detection electrode, suitable for detection of low concentration of oxygen content, measurement accuracy of micrograms. 2. The measurement part and the mobile phone APP are connected via wireless wifi. The communication is reliable and the distance is long. 3. The measuring part adopts IP68 dustproof, splash proof and waterproof shell, which can work alone. It is small in size, light in weight, portable, and has multiple mounting and placement methods. 4. The mobile phone APP is based on the android platform. Compared with the traditional communicator, the interface is more beautiful and more in line with the user's operating habits. 5. In terms of data processing, mainstream database technology is used to collect the data for big data processing, presenting users with rich data forms, guiding the use of users, and giving expert advice. 6. Multi-user mode, 1 transmitter can connect 4 mobile phones, 1 is in work mode, can operate the transmitter, and the rest of the mobile phone is in browse mode, can view the transmitter data.
