Optical   Method   Portable   Dissolved   Oxygen   Meter   utilizes   the   leading   international fluorescence  technology,  which  is  based  on  the  physics  principle  of quenching  of  active fluorescence by specific substances. The significant advantages of this fluorescence method of measuring dissolved oxygen are that it does not consume oxygen, has no flow limitation, does not require preheating of the electrolyte, and does not require maintenance and frequent calibration. The portable dissolved oxygen meter has automatic compensation for temperature and pressure and manual input compensation for salinity. The instrument is equipped with an operating keyboard and a backlight display with a simple interface, comprehensive functions and  easy  operation. The  instrument  can easily  perform  data  measurement,  data  storage, parameter setting, sensor calibration and other functions, and supports data export.
