Fluorescence dissolved oxygen analyzer

Instrument Overview:

The dissolved oxygen sensor included in the product adopts internationally leading fluorescence lifetime technology, which is based on the quenching principle of active fluorescence by specific substances in physics. The significant advantage of this fluorescence method for measuring dissolved oxygen is that it does not consume oxygen during the measurement process and therefore has no flow rate restrictions. At the same time, it does not require preheating or electrolyte, and is free from maintenance and frequent calibration. The response time of the Hengmei optical dissolved oxygen probe is as low as 30 seconds, making dissolved oxygen measurement more accurate, stable, rapid, and convenient.

Equipped with backlight display and operation keyboard, it has comprehensive functions and simple operation, with a simple interface. The dissolved oxygen optical sensor automatically recognizes, reads and stores measurement data, calibrates sensors, and other functions. It can also export USB data to achieve more high-end functions. Our consistent pursuit is to pursue high cost-effectiveness.
