OILGUARD 2

OILGUARD 2




Oil Trace Monitor for Mineral Oils

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.







  • Well-proven UV-Fluorescence measuring principle

  • True non-contact measurement in a free-fall stream

  • Dual-beam optics for highest accuracy and stability
