The OilGuard from SIGRIST-PHOTOMETER AG is the result of more than 15 years experience with online Oil-in-Water monitoring systems. The instrument has been developed in close cooperation with the oil industry and combines proven UV-Fluorescence technique with valuable features for an easy and reliable operation. These features include a proven contact-less measurement, which drastically reduces regular maintenance requirements and allows unattended operation over several weeks. A closed flow cell is available for clean media such as condensate or for the monitoring of oil leakage into cooling water. The dual-beam optics automatically compensates the effects of light source aging, temperature changes, etc. and guarantees long-term stability.
The quick response and high sensitivity of the continuous measurement classifies the OilGuard as a valuable monitor to react immediately to process malfunctions or accidents. User-specific calibration to as many as 8 oil grades allows using the OilGuard as reporting instrument to quantify the amount of oil; calibration can be done and adjusted on site.
Servicing of the flow cell and calibration checks can be carried out without switching off the power supply.
