The finger abrasion tester can simulate the abrasion process of almost all products and fingers/skin, and can truly simulate the liquid environment, such as human sweat, hand cream, sunscreen, detergent, toothpaste and other liquid media. The device can simulate the wear process including: finger wear, nail scratches, tooth wear, shoe sole wear and industrial scratches. When human fingers, skin, teeth and other media come into contact with various products, the surface of their materials will be worn out, which seriously affects the quality of the products.

Application areas:
 
　　Car (exterior painting, interior parts);
 
　　Ship engineering (interior, instrument testing);
 
　　Electronics industry (mobile phone, keyboard, touch screen);
 
　　 household/industrial electrical appliances (exterior coating, handrails);
 
　　Paper industry (writing, printing, money, security paper, special paper, passport);
 
　　Medical equipment (tooth coating, scale);
 
  Printing Industry;
 
　　Jewellery industry;
 
  Standards compliant:
 
International standard IEC 68-2-70, German/European standard DIN EN 60068-2-70, BMW GS 97034 / GS 97045, Daimler DBL 7384, Ford WSS-M2P188-A1, EWIMA Specification, Sony Ericsson 45/152 41-FEA 202 8139 Uen etc.
 
  working principle:
 
The main working principle of the 　　 wear tester/multifunctional finger abrasion tester is to apply a certain pressure through a test head, and carry a standard test cloth to the surface/coating of various materials, and perform automatic circular friction at the angle specified by the standard. The test conditions can be customized, including tests under dry and liquid conditions (sweat, lotion).
 
　　Technical characteristics:
 
　　 1. High simulation test, real simulation of chemical/mechanical wear process
 
　　2. High reproducibility and repeatability
 
　　3, standardized fully automatic test procedures
 
　　4, wide application areas
 
　　5. Flexible device settings, super durability and easy operation
 
  Technical Parameters:
 
　　1, load: 1, 5, 10 N (20N optional)
 
　　2, friction stroke: 1-40mm
 
　　3, the number of trials: 1 -100 million times
 
　　4. Test liquid supply: automatic circulation type
 
　　 5. Test fabric supply: automatic circulation type
 
　　6. ​​Power supply: 110 V / 230V
 
  Precautions:
 
　　 1. During the test, if the air compressor starts frequently, it means that the gas loss is large, which is normal.
 
　　2. If you observe the word "ERROR" on the airflow resistance indicator after starting the test, it means that the air resistance of the sample has exceeded the set value of 500Pa. You must immediately press the "Test End" button to protect the instrument.
 
　　 3. All parameters of the airflow resistance display table have been set, and non-professional maintenance personnel shall not modify it without authorization.
 
　　 4. The flowmeter must be used within the flow range, and it is strictly prohibited to use it over the range.
 
　　 5. If there is too much dust and impurities on the rotor of the flowmeter, which affects the accuracy of the reading, open the back cover of the instrument, open the manual ball valve in the box, and then connect the air source to clean the flowmeter. (In normal use, the ball valve in the box must be closed.)
 
　　6. ​​For the regulating valve that does not appear in the instrument manual, do not adjust it without authorization during the test.
