The ERICHSEN SmartPen is used to determine the scratch resistance of surfaces; depending on the used module, it can be used to determine the resistance to scratching, the tendency towards metal marking and the durability of printed markings. With the ERICHSEN SmartPen, a modular hardness test pencil with digital test force setting and display (resolution 0.05 N) is now available. The SmartPen is supplied in a plastic case with three springs and a USB-C charging cable.
PLC controlled test system comprising a basic unit and a control unit, with a motor-driven X-Y- specimen table, a universal holding fixture with vertical linear guide and pneumatic tool feed motion as well as a touch-screen control panel. In acc. To standards AFERA 4001 P11
Pocket instrument for scratch resistance (mar resistance) of painted or plastic surfaces. Test body (plastic, copper or steel disc) is applied with a pre-set force and drawn across the test surface. Spring force 0 – 20 N divided into 3 measuring ranges. (Model 435S for adhesion testing)
For various scratch hardness tests, e.g. in accordance with the process used in the industry making plastic panels. 5 different tools with diamond or carbide scratching tip. Force range: 0.1 – 10 N.
This successful and extremely useful scratch hardness tester is in the form of a pocket instrument. Also for tests on curved surfaces. Carbide ball tip, diameter alternatively 0.5/0.75/1.0 mm. Spring force 0 – 20 N divided into 3 measuring ranges. (Model 318S designed with rolling head) This instrument has been designed for the measurement of the hardness of protective coatings. The degree of hardness of paint films, plastic coatings, etc. can be accurately measured and recorded with the Hardness Test Pencil, Models 318, 318 S and 318 C, no matter whether on a level or curved surface, small or large.
Damping of the oscillations of a pendulum resting on the coating material in accordance with the standards. Konig and Persoz pendulum interchangeable. Dust cover included in the basic unit. Optional accessories: Opto-electronic counter with acoustic signal at test end with manual or automatic deflection of pendulum.
Pencils of various grades of hardness are moved over the painted surface at an angle of 45° to the horizontal with a force of 5 N, 7.5 N or 10 N (± 0.1 N). The pencil hardness is defined by those two grades of hardness the softer one of which just produces a writing trace while the next harder one leaves a perceptible scratch on the coating.
A steel block with circular indented inserts is applied onto the test surface and produces a pressure mark, the length of which is measured with a microscope. The impression hardness in accordance with Buchholz is established from the length of the impression, using the standard table
The optimized scratch hardness tester LINEARTESTER 249 is intended, in addition to its original purpose of application, i. e. to establish the ability of a surfaces to resist damage by scratching, also for several other tests: – Scribe/Scratch tests – To and fro-cycle abrasion tests – Crockmeter tests – MEK tests, tests determining the resistance against solvents in general or wipe test, respectively. Scratching force in the range of (0.5 – 20) N, with electromotive drive, including circular level, power pack and operating manual.
The motor-driven SCRATCH HARDNESS TESTER 430 P-Smart is a universal testing instrument designed for carrying out a wide range of tests on varnished and plastic surfaces to determine their resistance to scratches and cuts. Single cuts, parallel cuts and – by turning the specimen by 90° – cross-cuts can be applied to test panels of various thicknesses. The SCRATCH HARDNESS TESTER 430P-Smart is particularly provided for adhesion tests using the cross hatch cut method (in accordance with all mostly required standards) and for specific plastics tests according with Opel (scratch resistance and writing effect). For these as well as for further tests numerous setting possibilities on the basic instrument and a large variety of test tools are available to perform DIN EN ISO 2409, ASTM D 3359, JIS K 5600-5-6, SNV 37 111, VDA 621-411, ECCA T6, GME 60280, GMW14688 & many other test methods. Using the SCRATCH HARDNESS TESTER 430 P-Smart, series testing can be conducted with much greater ease. The results of testing are reproducible and well-defined. Optionally with manually actuated/motor-driven loading force and manually actuated/automatic test panel turn. Operation, documentation and data management via ERICHSEN-App
