DO-P258 pocket dissolved oxygen tester is composed of transmitter (measuring part) and controller (mobile phone APP). It has the features of high measurement accuracy, fast reaction speed, lightweight volume and simple operation etc. Users can download dissolved oxygen APP as a controller through mobile phones, which can view and operate equipment status, real-time data and historical data. It is mainly used to measure oxygen concentration of solution, and to test the low concentration D.O. in ultra-pure water. The meter can be widely applied in power, petrochemical and steel, etc.
Pocket Dissolved Oxygen Tester Features:
Polarography electrode to test the D.O., which is suitable for low concentration oxygen test. Measurement precision: μg level.
The transmitter and the mobile phone APP are connected by wireless wifi, so the communication is reliable and the distance is long.
Transmitter adopts waterproof configuration, with waterproof level achieves IP68, and it can work alone which is small volume, light and easy to carry. It has a variety of installation and placement modes.
Mobile APP is based on Android platform. Compared with traditional handset, its interface is more beautiful and more conforms to user's operating habits.
Adopt the mainstream database technology, the collected data are processed in a large scale, showing the rich data form for users, guiding the operation of users, and giving professional suggestions.
Multi-user mode: one transmitter can connect four mobile phones, one is in working mode, which can operate the transmitter. The other mobile phones are in browsing mode, which can view the data of the transmitter.
