The “OCD Xtra” combines multiple light wavelengths with multiple sensor technology, to measure oil accurately in the range 0-200 ppm, even in the blackest of produced water.
Multiple oil types are automatically compensated for by sophisticated algorithms. The multi – parameter display shows the sample’s oil content, pressure and a graphical average of the last 4 hours oil readings. The last 7 days readings are stored in ROM and can be accessed from the help menu.
The OCD Xtra has the ability to adjust the calibration settings against laboratory analysis on site. Full on screen help is available to guide the operator during set-up and maintenance routines
