Portable Whiteness Tester with Range 0%~120% Resolution 0.1% for Textile Dyeing

Note: Battery not Included During The Shipping !!!

Introduction:

• 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.

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. (Optional)
• Provide Bluetooth data out put choice. (Optional)
