IRHD Compact III

IRHD Compact III

Hardness tester digital, serial interface

The contact pressure and measuring time of IRHD Compact III   are designed according to standards.  IRHD Compact III also features embedded memory for the  saving of up to 300 test results and both optical and acoustic signals during measuring process.

The advantages of IRHD Compact III

If needed, the IRHD M or IRHD N indenter can be exchanged by customer easily For control and calibration works, only the measuring device in the transport case will have to be sent to Bareiss, while the test stand is remaining at customer's place.

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.
