Product Description Applications: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, chemical building materials, paper board, plastic products, white cement, ceramics, enamel, talc powder, starch, flour, salt, detergent, cosmetics and other substances.Principle:The instrument 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. 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 displayFeatures:* The optical path design is reasonable, simple. Adopt filter system with correction, the whiteness can be reflected quantitatively.* Use of high quality imported components.* No preheating after starting, measurements can be taken after simple calibration, easy to operate.* Able to memory 254 groups of measurement data.* 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 and other standards.* Use RS-232 data output to connect with PC.* Provide Bluetooth data output choice.Specifications:Range 0~120 Resolution 0.1 Illumination condition 45/0 Illuminant LED 457 nm Whiteness Formula Blue Light Whiteness WB=R457 Measuring Aperture ≤15mm Zero Drift ≤0.1 Stability of Display ≤0.5 Repeatability of Measurement ≤0.1 Operating Condition Temperature 0~40oC Humidity <85 %RH Power Supply 4x1.5V AAA size (UM-4) Battery (Optional AC Power Supply) Size Main Unit 156x67x28 mm Sensor 44x55 mm Weight 200 g (Not Including Batteries)Standard Accessories : 1.
