Optimized B2B Product Description
The TriForcePencil Model 293 represents a leap in scratch hardness testing, employing the Wolff-Wilborn methodology to ensure consistent application of force and angle throughout tests. This precision instrument streamlines the process, significantly mitigating manual error in pencil pressure application. Originally a 750g test weight was used, but in recognizing correct force naming, adaptations have been made to employ test loads of 7.5N. Erichsen’s TriForcePencil 293 features a unique weight block with three pencil guides, leveraging the ideal test load onto the pencil tip as per the guide’s positioning. The device allows for effortless setting of pencil projection through an easily adjustable screw. Its design includes recessed handles for a steady grip, ensuring smooth operation over the surface under test.
Encased in a durable plastic, the TriForcePencil 293 comes with an assortment of 17 pencils, ranging from 6B to 9H in hardness, along with a special sharpener and emery paper. As a favored method within the scratch hardness testing sphere, the pencil technique is both straightforward and fast for determining coating surface hardness against sharp or abrasive stresses. Moreover, this tool is perfectly suited for in-production applications like coil coatings. Its tri-load capacity (5 N, 7.5 N, 10 N) addresses the growing demand for variable test load capabilities, making it a versatile choice for global markets.
