G238BB Electronic Crockmeter / Electronic rubbing colour fastness tester
G238BB Electronic Crockmeteris used for testing the color fastness of fabric and leather by dry/wet rubbing.The tester makes the sample repeatedly rub the specified number of times with the white cotton cloth in a certain pressure and a certain stroke. After comparing the white cotton cloth with the stained gray sample card, the decolorization grade of the fabric, leather, coating and other samples is evaluated, which provides the basis for improvement of fabric dyeing. This instrument is equipped with digital electronic preset counters. experimental data repeatability can help producers effective control of the production.
Standards compliant:
ASTM F1319 Standard test method for determining the antiwear and antifouling properties of images produced by office reproductions ;
AATCC 8 165Test method for colour fastness to rubbing ;
BS 1006 D02 Test method for colour fastness of textiles and leather;
GB/T 3920 Colour fastness of textiles to rubbing ;
ISO 105 D02 X12 Textiles colour fastness test part;
X12: colour fastness to rubbing ;
JIS L0849 Test methods for colour fastness to rubbing M&S C8/C8A NEXT TM6.
Application：
1.suitable for evaluating the color fastness of various textile,leather,printing and dyeing materials after rubbing.
2.Designed as a whole, mainly composed of base, friction drive mechanism and counter;Simple structure, compact and beautiful,convenient and fast loading.Easy to use and understand with stable performance、 accurate experimental data and good repeatability, reduce the requirements for operators, but also greatly improve the test efficiency.
Technical advantages:
1. Simple
It has the characteristics of simple operation and less daily maintenance and can run automatically until the end of the test or the sample is damaged.
2. Quiet
The special muffler mechanism allows you to avoid the sharp friction sound between iron parts during daily testing.
3. Accurate
The three-point one-line design meets the standard stroke and pressure, ensuring accurate and effective test results.
4. Selectivity
The standard friction head and multi-performance design meet various standard requirements and enhance the cost-effectiveness of the instrument.
5. Convenient
The use of new technology and scientific sample fixing function can evenly fix the sample fabric to avoid wrinkles, and the operation is convenient and fast.
6. Features
Carefully designed, embodied, digital programming counter, red wave stainless steel button, durable and atmospheric.
7. Abnormal protection
Power-off protection-save the current test data for you when the power is off, and you can view the last test data when the power is on next time.
