Triple Shore A

Triple Shore A

Measuring principle

Three indenters penetrate from the top surface of the sample simultaneously with a standard conformable force. Each measurement is then taken indenpently to generate three hardness values from one single operation. Samples with uneven surfaces can be compensated by individual bearing system in the device.  


  • Time saving 
  • Automatic statistical evaluation   (Median / Average) 
  • Automatic error detection 
  • Descending speed of 3.2 mm/s according to the standard

Range of application 

Hardness determination on soft rubber, Elastomers, Natural rubber products, etc.

Reference plates

Standard rubber blocks are used to ensure the metrological capability of the measuring device acc. to IRHD during the frequency of recalibration. The rubber blocks are embedded in a holder made of stainless steel.       


Hardtest - the test - and evaluation software program

Applicable for all electronic Bareiss testing devices with a serial interface. The programme contains all functions which are necessary for a faultless process

DAkkS/DKD calibration certificate

DAkkS/DKD calibration certificate

When a measuring instrument is being calibrated, the given deviation is determined by various measurements versus standard references. A calibration certificate is then issued indicating the measuring results and the corresponding measurement uncertainties and the instrument is marked as calibrated. 

All documents together with the calibration certificate provide traceability of national standards.
