Dissolved oxygen analyzer

Overview:

The dissolved oxygen sensor included in the product adopts the 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, so there is no flow rate limit. At the same time, it does not require preheating or electrolyte, and is free of maintenance and frequent calibration. The response time of Hengmei Optical Dissolved Oxygen Probe is as low as 30 seconds, making dissolved oxygen measurement more accurate, more stable, faster and more convenient.

With backlit display and operation keyboard, it is comprehensive and easy to operate, with a simple interface, automatic recognition of dissolved oxygen optical sensors, reading and storage of measurement data, sensor calibration and other functions, and USB data export to achieve more high-end functions. The pursuit of high cost performance is our consistent pursuit.
