Description:

A common error when using a durometer is to imbed the foot of the gage into the specimen by pressing down with excessive force.  All Rex instruments are made in accordance with ASTM D-2240.  This standard states that for types A, B, and O the gage should be pressed onto the specimen with a load of 1 kg.  The Rex Constant Load Weight for gages with an 822g spring load (types A, B, O) slides onto the lower barrel of the gage, gives it a wider foot, and raises the mass of the gage to the suggested 1kg. With the load weight on the gage, all the user has to do is set the gage on the test specimen - no further pressure is necessary.  Thus the Constant load weight eliminates the human error that would otherwise occur due to users pressing on excessive or inconsistent force. Constant Load Weights are precision CNC machined from stainless steel and are polished and calibrated by skilled craftsmen at Rex Gauge Co. in the USA. **Note: Increasing foot diameter can effect durometer readings.
Note: Rex Gauge Durometer Models 1500, H-1000, 1700 and 2100 are not recommended for use with operating stands or constant load weights.
