WM-106 Digital Whiteness Meter Whiteness Tester Range 0~120% WM106

Brand: Graigar

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.
• Able to memory 254 groups of measurement data.

Part Number: WM-106

Details: 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.
