The kit consists of 3 color coded test blocks.
• Orange 13
• Gray 30
• Black 90
The indicated readings are derived from an average of 6 readings taken with our standard durometer calibrated regularly. For periodic verification of calibration accuracy, take an avarage of 3 readings in different spots on each test block. The result should be approximate to those shown.
Results comparasions may vary between durometers with non-similar configurations.
