TTM-48A Brightness and Color Tester is the first new automatic one-button measurement of all color and whiteness technical parameters in the industry developed by the company. It is widely used in paper-making, printing, textile printing and dyeing, ceramics, building materials, chemicals, food, salt production and other industries and other production and commodity inspection departments that need to determine the color and whiteness of objects.
Application Range
Paper, cardboard, plastic, pulp, Salt, industrial salt, starch, calcium carbonate, talcum powder, etc.Chemical pulp, cotton, chemical fiber, textiles
Grain, ceramics, enamel, building materials
Application Function
- Measure the color of the object
- Measure CIE whiteness (Gantz visual whiteness) W10 and color cast value Tw10
- Measure ISO whiteness (R457 blue lightness) and Z whiteness (Rz)
- Measure the fluorescence whitening caused by the emission of fluorescent substances (the sample contains fluorescent whitening)
- Measure the whiteness of building materials and non-metallic mineral products WJ
- Measure Hunter Whiteness WH
- Measure the whiteness and color of the fiber (supporting fiber sampler)
- Measure the whiteness of the powder, Lab and color difference
- Measure the lead concentration
- Measurement of yellowness YI, opacity OP, light scattering coefficient S, light absorption coefficient A, transparency, ink absorption value
Product Features
- Large screen and high pixel liquid crystal display module,display and prompt the operation steps to display measurement and statistical results,friendly man-machine interface makes the instrument easy to operate
- Increase data cache, which is convenient for users to back up, review, and compare historical data. It can store up to ten reference information.
- The instrument has a power-off protection function, and the calibration data will not be lost after power-off.
- can be measured multiple times and gives the arithmetic mean of a series of measurements
- Measure the color of the object, report the diffuse reflection factor Rx, Ry, Rz, stimulus value X10, Y10, Z10, chromaticity coordinates x10, y10, brightness L*, chromaticity a*, b*, chroma C*ab, hue Angle h*ab, dominant wavelength λd, excitation purity Pe, color difference ΔE*ab, brightness difference ΔL*, chroma difference ΔC*ab, hue difference ΔH*ab, Hunter system L, a, b
- Using thermal printer core, no need to use ink and ribbon, no noise when working, fast printing speed, etc
- This instrument is equipped with standard RS232 interface, which can be used with PC software for communication (optional)
