BYK-Gardner Byko-Swing (5867) Konig/Persoz Hardness Tester for Coatings

Product Description
The byko-swing hardness tester is an instrument to determine the elastichardness of coatings according to DIN EN ISO 1522 and ASTM D 4366. It consists of a sample holder where a pendulum freely swings on the sample surface anda counting device.
The number of swings in a defined angular range is a measure for the elastichardness of a coating. It is expressed in seconds or number of swings. The num-ber of swings is detected by light barriers in the lower part of the instrumentand is shown on the display as seconds or swings.

The byko-swing offers a fully automatic measurement mode - no manual in-teraction is required.

Fully automated instrument for measuring pendulum hardness in accordance with the König and Persoz methods.
~ Automated design ensures reliable and repeatable measurement of coating hardness by reducing operator intervention
~ Motorized sample platform lifts the sample into the test position
~ Pendulum is positioned and released automatically
~ Automatic counter with signal when deflection is below 3° (König) or 4° (Persoz) respectively
~ Changeable from König to Persoz and vice versa with corresponding pendulum
~ Pre-assembled draft shield with easy access door
~ UL/CE/CSA certification
~ Compliant with ASTM D4366 and ISO 1522
~ Smallest sample size: 65mm x 75mm (2.6 x 3.0 inches)
~ Largest sample size: 102mm x 229mm (4.0 x 9.0 inches)
~ Maximum sample thickness : 8.5mm (0.33 inches)
~ Minimum sample thickness is limited by the rigidity of the sample.
