0911472255- Ex protection class II 2G Ex px IIC T4 (ex zone 1)
- Complies with IMO resolution MEPC.107(49)
- Non-contact flow cell avoids window soiling
- Low influence of suspended solids due to fluorescence principle
- Easy adjustment with secondary standard
- Alarm contact 15 ppm
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 and the version Ex M complies with the IMO standard MEPC.107(49).
