便携式Colorimeter

ColorQA Series 4 Portable Colorimeteris a color comparison device that digitally measures the RGB of a Target Color and then allows the user to sample any number of comparison colors to determine a color match. It is light weight, portable, hand held and battery operated. Colors are read by pressing the tip of the ColorQA against the surface of the color to be read and pushing the read button. The results of the color comparison are displayed on an LCD screen. The screen shows the read out for the Target Color on the first line, the read out for the Sample Color on the second line and the differences in the two colors are shown on lines 3 and 4. Line 3 shows the simple numerical differences in color and line 4 shows the differences expressed in a percent difference for each of the three color zones being evaluated. The three color zones measured by the ColorQA Series 4 are Red, Green and Blue. Accessories Calibration Cap. This cap contains a metallic disk which is painted with a super bright barium sulfate coating. When discolored it is critical to replace immediately. Rubber Cup. This cup is used to block out ambient light for irregular surfaces such as when measuring paint colors on textured walls. Rubber Tips. This tip fi ts nicely over the sensor tip of the device for use in tighter zones than the rubber cup, but as in the case of the rubber tip, the irregular surface require a tight fi t to block out ambient light. Plastic Cap. This cap is used to protect the internal optics when measuring powders and liquids. The use of this tip creates a fl at area of the material at a constant distance from to sensor for consistent readings. 6 Volt J Cell batteries. This is the battery used in the device.
