Advanced Technology Reflectance Unit
After aging and cooling, fuel samples are filtered and the average amount of filterable insolubles is estimated by measuring the light reflectance of the filter pads. The 100% and 0% extremes of the reflectance rating range are defined by an unused filter pad and a commercial black standard, respectively.
- Easy-to-use operation
- Ratiometric measurement of reflectance
The K30700 is easy to use and contains state-of-the-art electronics. To measure reflectance ratiometrically, two calibration points are required. The instrument uses a black cavity standard and a standard plaque. The black cavity standard is designed to have nearly zero reflectance and the standard plaques are calibrated to a traceable national standard with a known reflectance. The first calibration point is referred to as the “dark” or “zero” offset. When a plaque of known diffuse reflectance is placed on the search unit, it produces a voltage in the photosensor array proportional to the light reflected from the plaque. This provides the second or “reference point” of the calibration
