The Sigrist OilGuard, Oil-in-Water Monitor, operates on the proven UV fluorescence measuring principle. Aromatic hydrocarbons possess the ability to emit visible light when radiated with UV light. This makes it possible to detect oil-in-water in the low ppm range even if the water is turbid. Note the system can be provided with certifications for Hazardous areas – Class 1 Div. 1 & 2 & EEx-p IIC.
1. OilGuard 2 W
Oil trace monitor for water treatment.
The instrument is used for monitoring oil traces in raw, surface, process and waste water. As a result of the non-contact free-fall measurement, there are no reading falsifications arising from window soiling and there is an extremely low need for maintenance. The instrument’s factory setting is calibrated with 16 EPA-PAH standard. The OilGuard 2 W can be recalibrated by the customer with a secondary standard (solid reference) which allows an exact recalibration without 16 EPA-PAH. The ingenious instrument design of the OilGuard 2W in combination with the high quality of its optical components minimizes the effect of interferences. Thus, even the smallest traces of oil, as well as larger amounts, can be precisely detected. The instrument can be adapted to various types of oil to meet customer requirements. Checking the instrument is easy with corresponding solutions.
