Pendulum Hardness Tester

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.
