Hardness

Pencil Hardness, Durometer, Barcol, Buchhotz, Scratch, Tabor.. Everything from Basic to Automated

DUROMETER

DUROMETER

The Shore Durometer is widely used to test the hardness of soft materials.A round point indents the material under a fixed force spring and the hardness is displayed on the dial.  The instrument can be either hand held or fitted to an optional stand for increased repeatability

Pendulum Hardness Test

Pendulum Hardness Test

The TQC Pendulum Hardness Tester has a lot of unique features that ease defining hardness by the Konig and/or Persoz method . Both methods work on the principle that the damping time of a pendulum oscillating on a sample indicates the hardness.

Pencil

Pencil

The pencil hardness test is perhaps the most simple form of hardness test. Pencils are pushed into the sample and the coating hardness is identified by the trace generated.

BARCOL

BARCOL

Used to check the hardness of many materials including plastics, polyesters, leather, and soft metals.  When pressure is applied to the device, a point penetrates the material and the degree of hardness is displayed on a dial, which is graduated from 0 to 100.

BUCHHOLZ

BUCHHOLZ

The buchholz hardness tester is used for measuring the hardness of a coating by indentation of a bevelled disc indenting tool with a sharp edge. The bucholz tester is placed on the coating for 30 seconds and the indentation length is then recorded. The length of the trace is inversely proportional to the hardness.

Sclerometer

Sclerometer

This simple sclerometer contains a round tip which is compressed by a spring. The amount of compression on the spring increases the force as the tip is pressed into the coating - by varying the force the user can determine the coating hardness.
