Intelligent and Unidirectional Scrape Tester
DMUM-25

Description of Product

Executive standard: GB/T4074.3-2008/IEC60851-3

Inspection standard: JB/T4279.9-2008

Meet GB/T6109-2008 standard requirements

Used to test the film scrap resistance of enamelled round wires with nominal conductor diameter above0.250mm;

Application of SCM control，enter the weight value, operation will be completed automatically: put down the scraping rod, stop while film scratch, calculate and show the scraping force, raise the scraping rod, return to zero, sample rotates 120°and repeat the same operation, calculate and show the scraping force of three times and average scraping force.

When film is scratched, film scraper would automatically stop scraping, with exposed conductor of sample＜3mm

With the advantages of high sensitivity, good repeatability, stable and reliable characteristics.
