The Zwick digital IRHD Micro Compact hardness tester consists of a basic unit with integrated electronics and display, a height-adjustable support table for the specimens and a column with built-in IRHD micro measurement device (DIN 53519-2).

It can be used for testing O-rings, seals, mouldings and hoses; a minimum thickness of 0.5 mm is required. 
 
A 2-line LCD display shows measurement range, measurement time and measured value. The measurement time (0 – 75 s) and language (English, French or German) can be set via coding switches. 
 
testXpert^® testing software allows the measured value to be transferred via RS232 interfaces for reprocessing and archiving. The test results are automatically transferred to a purpose-made test report and statistically evaluated.
