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 Conforms to the specifications of:ASTM D6468, ASTM D1455, ASTM D3052, ASTM D523, ASTM D2457, ASTM E97, ASTM C347, ASTM C346, ASTM C584, FTM 141 110-240V 50/60Hz (H x W x D): 10x8x4.5 in (25.4x20.3x11.4 cm) K30700-1 Y Search Unit for K30700 Reflectance Meter K30700-2 Green Tristimulus for Y Search Unit K30700-3 Reflectance Standard 76-80% K30700-4 Polished Black Glass Standard (2” x 2”) K30700-5 PC Interface K30700-6 Data Save Please login to access resources »
