1Product Introduction

GermanyTintometerProduced by the companyLovibond^®BODThe measuring instrument comes standard with a six digit measuring system and can also be upgraded to a twelve digit measuring system. Unlike traditional dilution methods, this instrument uses the internationally recognized respiratory pressure difference method to accurately measure the concentration of samplesBODValue.

2、 Measurement principle

The water sample is placed in a closed container, and under constant temperature and stirring speed, microorganisms decompose certain oxidizable substances in the water. The oxygen consumption before and after the reaction is measuredBODTo express. The carbon dioxide generated during the reaction process is absorbed by potassium hydroxide. The instrument senses pressure changes in the culture bottle through sensors and converts them intoBODValue, directly based onmg/lThe form is displayed on the screen.

3、 Product Features
