Our top-quality Pusey & Jones (P&J) hardness tester (Plastometer) serves for the determination of the penetration depth on rubber and elastomer materials like rubber rollers and standard blocks made of rubber with a minimum thickness of 13 mm as well as paper rollers.
The electronic dial gauge is integrated into the instrument and shows the indentation depth to an accuracy of 3 decimal places (0.000 mm). With the help of a vertical spindle that is integrated on the back of the instrument, the dial gauge can be moved up and down conveniently and precisely.
The dial gauge is equipped with a zero setting function. Zero can be set by a single press of the zeroing key as soon as the indenter, together with the measuring bar, is lifted about 3 mm by lowering the body of the instrument.
The prescribed total load of 9,8 N is applied by lowering the loading lever on the right side. The test result can be read after a test time of 60 seconds. The basic equipment includes adjustable feet which can be adjusted according to the test object.
Our customer who produces rubber rolls will be able to determine the hardness of the rubber efficiently every day now with the purchase of the P&J tester.
