TESPRO CO.,LTD. List of Products and Services

All cells of the melamine sponge are filled with abrasive gel. The synergistic effects of the melamine sponge, abrasive, and gel thoroughly remove dirt without damaging the contact probe. When a contact probe is inserted into the sheet, the abrasive grains are pressed against the probe surface, removing dirt. The sticky gel clings the dirt and prevents re-contamination. * Please use the basic cleaning sheet for plated contact probes.
