This is for determining the lateral extension of 15 cm dia. x 30cm high cement concrete cylinders while testing them under compression.  

 

Specifications:

 

The unit consists of two movable frames pivoted at one end.

The extensometer is fixed to the specimen with the help of tightening screws.

The lateral extension is indicated on a dial gauge of .002mm x 12mm travel.

The extension is magnified 2.5 times and the dial gauge readings are to be divided by 2.5 to get the exact read-ings. A spacer strip is provided to initially set the dial gauge, and can be removed after initial setting.

Supplied in a wooden carrying case.
