OILGUARD EX M

Oil Trace Monitor for oil discharge monitoring

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).

• 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
