Brief introduction

Our newly launched dissolved oxygen analyzer adopts advanced fluorescence testing technology, which has the advantages of low maintenance, easy calibration, fast and accurate testing.SD 400 Oxi LThe fluorescence method dissolved oxygen tester is equipped withFluorescent electrode, based on the principle of fluorescence measurement, does not consume oxygen and has stable measurement results at any flow rate. Easy to maintain.
