The optical method portable dissolved oxygen meter uses the leading international fluorescence technology. The significant advantages of this fluorescence method of DO measurement are that it does not consume oxygen, does not require polarisation, does not require frequent calibration, and is not subject to interference from H2S, heavy metals, oils and greases, acids and bases. The portable DO meter has manual input compensation for temperature, pressure and 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 achieve data measurement, data storage, parameter setting, sensor calibration and other functions.
