EP3000B fully automatic infrared oil analyzer

1Compliant with standards

Compliant with national standards“HJ637-2012Water quality - Determination of petroleum, animal and vegetable oils - Infrared photometric method”

2Working structure principle

Composed of fully automated operation software, infrared spectroscopy system, and magnetic stirring extraction system, using extraction solvents（CCl4orC2Cl4）According to a certain extraction ratio, the drum type three-dimensional stirring technology is used to extract the oil in the water body, and then the extraction solution is introduced into the colorimetric dish after removing water and impurities. Then, the infrared oil analyzer detection system is used for analysis and measurement. After the measurement is completed, the instrument automatically discharges waste and cleans the pipeline.

Fully automated, without the need for operators to come into contact with carbon tetrachloride, including automatic sampling, extraction, water and impurity removal, measurement, cleaning, drainage, and data storage.
