Spec Whiteness Meter is mainly used to directly measure the whiteness value of object or powder with flat surface. Can be widely used in whiteness measurement of textile printing and dyeing, paint, chemica Features   * It consists of Light Source, Optical System, Detection System, Data Process and Display System. The whiteness Calculation Formula of the instrument is blue light whiteness R457. * Use of high quality imported components, good reliability. * The optical path design is reasonable, simple. Adopt filter system with correction, the whiteness can be reflected quantitatively. * No preheating after starting, measurements can be taken after simple calibration, easy to operate. * Pass strict inspection and testing, the instrument conforms to the JJG 512-2002 Whiteness Meter Verification Regulation. Also conforms to GB3978, GB3979, GB7973, GB7974, ISO2470, GB8904.2, QB1840, GB2913, GB13025.2, GB1543, ISO2471, GB10339, GB5950, GB12911, GB2409 and other standards. * Able to memory 254 groups of measurement data. * Use USB data out put and RS- 232 data out put to connect with PC. * Provide Bluetooth data out put choice.   Principle   The light source of the instrument is long-life LED with 457nm, conforming to the light source requirement in the JJG 512-2002 National Metrological Whiteness Meter Verification Regulation. The measurement of the instrument adopts the principle of photoelectric effect. The diffuse reflectance Radiant Brightness Energy Value of the sample surface is receive by the optical cell. Then, the value is amplified by high-precision auto zeroing operation amplifier, inputted to the calibration circuit for energy calibration. Then, the whiteness value of the sample is directly shown on the digital display.   Specifications   Range 0~120 Resolution 0.1 Illumination Condition 45/0 Illuminant LED 457nm Whiteness Formula Blue Light Whiteness WB=R457 Measuring Aperture <<15 mm Zero Drift <<0.1 Stability of Display <<0.5 Repeatability of Measurement <<0.1 Operating Gondition Temperature 0~40ºC Humidity <85%RH Power Supply 4x1.5 V AAA(UM-4) Battery(Optional AC Power) Size Main Unit 156x67x28 mm Probe Φ44x55 mm Weight 200g(Not Including Batteries)   Accessories Model WM-106 WM-206 Standard Accessories Main Unit External Probe AC Adaptor Standard White Board Optical Cleaning Cotton Cloth Carrying Case(B04) Carrying Case Operation Manual Optional Accessories Constant Pressure Powder Forming Apparatus AC Adaptor RS-232 C Data Cable with Software Bluetooth Data Adapter with Software       .
