Rebound Check

Schob type Rebound Tester fitted with touch-screen Display system for the calculation of the resilience of elastomers with hardness between 30 and 85 irhd.

Instrument characteristics 
The instrument measures the resilience of elastomers with hardness ranging from 30 to 85 IRHD points.
The Resilience is the ratio between energy yield and energy applied in the impact between the instrumet's hammer and the specimen having dimensional characteristics defined by the standards.
This measure provides useful indications regarding the dynamic behavior of an elastomer.
The measurement is performed by determining the rebound angle of the hammer following the impact.
The instrument provides direct reading of the resilience value.
The results of 5 tests performed on the specimen, their mean and standard deviation are displayed.
Instrument control 
The touch-screen display installed on the instrument permits to:
• Display the results of 5 tests made on the sample
• Calculate mean and standard deviation of the results
• Calibrate the angle reading of the instrument
• Export the data

Sample Holder 
The sample holder is conforming to ISO 4662 and ASTM D 7121 standards. The application tool supplied with the instrument premits easy insertion and removal of the sample.
Software for data import 
Gibitre_Serial Connection software for data storage and printout.
