G238BB Electronic Crockmeter is 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.

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.
