The Test Block kits are used as a reference guide for users of Shore A type durometers.

If you are using your durometer as a hand device, the test block kit allows the user to get a "feel" for the correct pressure to use when testing for certain levels of hardness. This helps reduce errors caused by applying incorrect load pressure.  

The blocks can also be used as a reference to check for calibration and also verify accuracy against any unexpected results.

Shore A - Kit includes 7 pieces measured in HA (36, 42, 55, 67, 75, 85, 94) approx.*

Accuracy: ±2 HA

* Please note hardness values are subject to change, at the manufacturers discretion.
