Yushan Portable Fluorescence Dissolved Oxygen Meter is a new generation of dissolved oxygen meter launched by Yushan Sensing, which adopts the internationally leading fluorescence lifetime technology. It includes an internationally leading fluorescence dissolved oxygen sensor independently developed by it and an intelligent instrument controller originally created by Yushan. It can quickly and accurately measure dissolved oxygen content, and has automatic compensation function for water temperature and atmospheric pressure. At the same time, it can also be connected to smartphones and tablets via Bluetooth, and can be controlled by mobile phones or tablets with the support of Functions that cannot be achieved by the instrument. Scope of application
It is suitable for aquaculture water source monitoring, sewage treatment, environmental protection monitoring and other industries, and is especially suitable for use in the wild and on-site.
Measurement Principle
The fluorescence dissolved oxygen meter is based on the principle of quenching active fluorescence by specific substances in physics. The blue light emitted from a light-emitting diode illuminates the fluorescent material on the inner surface of the fluorescent cap. The fluorescent material on the inner surface is excited and emits red light. The phase difference between the red light and the blue light is detected and compared with the internal calibration value. , thereby calculating the concentration of oxygen molecules, and automatically compensating the temperature and air pressure to output the final value.
Intelligent Controller
The original technology of Yushan Sensing Technology organically combines the world's leading sensor technology with the ever-changing mobile Internet technology to provide a new generation of powerful intelligent products for the water quality monitoring market. .
Yushan Sensing Technology supports smartphones or tablets that can run on the system. It makes the water quality testing process easier, the on-site data status collection is more accurate, and the information processing and communication are more timely and smooth.
