The OilGuard works on the fluorescence principle. The design uses a free-fall measuring system that eliminates contact between the sample and the flow cell. Adoptions to various types of oil are carried out by means of calibration curves, a control glass makes it easy to check or recalibrate the instrument. A pressurized-enclosure version is offered for areas requiring explosion protection.
