Multi-Finger Scratch / Mar Tester is used to measure the relative resistance or susceptibility of a material surface to scratching, marring, gouging, scraping, engraving and other similar physical damage not classified as ordinary wear. Based on the apparatus described in popular automotive specifications, the instrument is commonly referred to as a five-finger (five-arm) scratch & mar tester and most often used to evaluate plastics.
This Multi-Finger Scratch / Mar Test instrument is used to evaluate the scratch and mar resistance of resilient materials. A variable speed, pneumatically driven sledge is moved below five independent, weighted scratch "fingers" that are equipped with interchangeable scratch tips. Includes: spline shaft 'finger' assembly (5); scratch tip with 1.0mm diameter hemisphere (set of 5); mar tip with 7.0mm diameter hemisphere (set of 5); weight set (consisting of 2N; 3N; 4.5N; 5N; 6N; 7N; 10N; 15N; and 20N); and specimen clamp.
Though robust in design, this instrument is precision-machined. Never drop it or knock it over Always clean the instrument after use.
Clean the instrument using a soft dry cloth. Never clean the instrument by any mechanical means such as a wire brush or abrasive paper. This may cause, just like the use of aggressive cleaning agents, permanent damage.
Do not use compressed air to clean the instrument.
Always keep the instrument in its case when not in use.
We recommend annual calibration
SAFETY PRECAUTIONS:
Not suitable to be put in the sun or in the high light
Avoid using it in over-high or over-low temperature environment
Avoid humidity
Always make sure the instrument is connected to an earthed electric socket.
Always make sure the instrument’s power is turned off while adjusting any electric component
A knife is a sharp object. Be careful when using it.
