Sci-tech Creep Testing Machine Model MT 070 is designed to carry out practices on specimens of plastic materials. Due to the dependence on the temperature in this type of tests, there is a temperature conditioning box where the experiments are carried out. It is made of acrylic, which allows to observe the practices development. The conditioning box is divided in two sections: the first has the placement for an isotherm bag that allows heat or cold the inside of the box, and the second one is for the placement of the specimens. Inside it, there is also an alcohol thermometer to measure the working temperature.

To carry out a creep experiment a constant load of tension must be applied to the specimen. The unit has a load arm over which a hook for weights is hung on an end. This load arm multiplies the load applied to the specimen. The student will be able to apply loads by adding the weights supplied. The reaction will be the force applied to the specimen.

The unit has a dial indicator to measure the specimen elongation in a continuous way. The dial indicator measures the arm fall to the horizontal and the specimen elongation is obtained by a simple trigonometric relation.
