The model OIL-20A is intended for extracting oil from samples with tetrachloroethylene and then measuring its concentration. Because of its separate extraction and measurement design, the inclusion of any suspended matter in the test water poses no problem, and after measurement of high concentrations, the cells can be easily cleaned. Besides that, the model’s digital display allows for measuring oil down to 1.0 ppm or less.
