The YE0153 is designed for evaluation of the halftone reproduction of electronic cameras. Two 11-graduated counter current gray scales are arranged on a gray background (D=0.75), the gray scale being graduated logarithmically.  

Related to the densities of the gray scales: gamma = 0.45

Related to the reflectance values (brightness): gamma = 2.2 , that being exactly the reciprocal value of gamma = 0.45.

The output signal of an optimally gamma-corrected camera yield two 11-graduates counter current linear step signals. The contrast range of the gray scales is 40 : 1.

The values of the 11-graduated gray scale are as follows:

 
Step Density Reflectance in %
1 0.05 89
2 0.13 74
3 0.22 60
4 0.32 48
5 0.43 37
6 0.55 28
7 0.69 20
8 0.88 13
9 1.06 8
10 1.31 5
11 1.65 2

The density values are based on BaSo4 = 0. Two black fields and a white field are located between the gray scales, the density of the black filed is D > 2.4 (reflectance < 0.5 %). The density of the white filed is D = 0.05 (reflectance = 89.9 %).

FAQs About  Grayscale Charts

Plastics, glasses, films, coatings, PET carboys，and packaging materials are common uses of hazemeter to monitor consistency and quality. 


Depending on the scale of the manufacturer, its matte, low-sheen finish can be called gloss level 3. Overall, gloss levels in certain standards go between 1 (flat) to 7 (high gloss). Level 3 is considered low-gloss or satin-like.


3nh Instrument Recommendation for Translucent Materials

1. YS6002 / YS6002-M Color & Haze Meter

Equipped with d/8° integrating sphere and D/0 transmission structure, it comprehensively tests color difference, haze, transmittance and yellowing index. Ideal for translucent film, frosted glass, milky plastic and liquid samples, perfectly suitable for laboratory and production quality control.

2. KS1500 / KS1510 Color Haze Meter

Adopts large integrating sphere and full-spectrum optical design, delivers stable diffuse transmission data. Specially optimized for thick translucent sheets and high-haze materials, ensuring accurate and consistent color measurement.

3. TS8560 Spectrophotometer

High-precision benchtop model with dual reflection & transmission measurement modes. Supports SCI/SCE detection, with excellent inter-instrument agreement, meeting strict color inspection standards for high-end translucent materials.

4. TS8510 Portable Spectrophotometer

Compact and portable, optional transmission accessory for fast on-site testing of thin translucent samples. Great for factory spot inspection and mobile quality checking.


a. Check whether the USB cable is connected. If not, please connect it. Check whether the connection is effective. You can re-plug the USB cable to test.

b. If the USB cable is connected well but the interface still displays "USB Disconnect", please re-start the colorimeter and enter "Menu" -"Comm"to start the communication.

c. Change the USB cable or change the USB port in you PC.

a. If this phenomenon occurred, it means the battery power is not enough. You need to charge the battery.

b. When charge the battery, please insert the battery to the instrument, and plug in the adapter to charge the battery. After 5 minutes, the instrument can be turned on.

c. If the instrument still cannot be turned on after charging 5 minutes, you can pull out the adapter and re-plug in to check it. Or repeat this operation.

d. If the instrument still cannot be turned on after charging 5 minutes, you can turn off the colorimeter and turn on it again to check it. Or repeat this operation.

e. If you have tried all the methods above but the colorimeter still cannot be turned on, please change the battery.

The gloss meter is used to measure gloss at typical angles (typically 20°, 60°, or 85°). The instrument illuminates the material and measures the amount of light reflected and states the outcome in gloss units (GU), which is related to perceived brilliance.
