• Other measurement, recording and measuring instruments

Hardness measurement is an important item for the characterization of various rubber, elastomer, and plastic products, and durometers (spring-type hardness testers) are widely used as instruments to obtain this data. They are portable, extremely easy to use, and can conduct non-destructive testing, among other main features. The basic structure involves pressing a predetermined shape of an indenter against the surface of the sample using the force of a spring, causing deformation. Hardness is measured based on the "depth of indentation" of the indenter when the resistance of the sample and the force of the spring are in balance.

• Testing Equipment and Devices

The pressing force of the instrument on the sample is always kept constant by a static load from weights. The pressing speed is maintained at a constant rate by a lifting mechanism using an air damper, and it can also be adjusted using a speed control knob. Additionally, unlike hydraulic dampers, there is no concern about oil leakage or the need for oil replenishment. By adopting a flexible joint mechanism, the instrument's pressing surface reliably contacts the measurement surface of the tilted sample. It is possible to obtain measurement pressures of 500g, 1000g, 1250g, and 5000g (depending on the model). It can be used with both analog and digital hardness testers.
