Description: Model 320 Fill 118 Copy 1 Created with Sketch.

The Model 320 Durometer Stand is an accessory to PTC®’s line of durometers and is also fully compatible with most durometers of other manufacture.

A unique, spring load cell can be easily set for precision A or D spring loads. This system eliminates the need for two separate stands. Heavy and bulky weights are not used, making the stand very portable and easy to use. The load cell must be set to “A” for Types A, B and O durometers or set to “D” for Types C, D and DO durometers.

To set to Type A, the upper part of the load cell is lifted and turned so that the head of the setscrew on the shaft fits into the slot at the imprinted “A” on the upper part. The same procedure is used for D scale, only the head of the setscrew is fitted into the slot marked “D”.

The material to be tested is placed on the stand’s table. The large knob at the lower right of the stand is turned to raise the stage. When taking a reading, the stage and sample are raised until the upper part of the load cell just begins to separate from the load cell housing.

This point marks the fully loaded position and the durometer will then register the hardness of the sample.
