Title: Universal mechanical testing device

Abstract: A universal material testing device which includes a frame; an actuatormounted on the frame for controlling a displacement of a sample to betested; a load cell movably mounted on the frame and adapted to abutagainst the sample for detecting a force applied thereon by the actuator,the load cell producing a signal corresponding to the force detected; asignal conditioning unit for reducing input noise and for processing ofthe signal and executing specific tests by coordination of displacementcontrol and load signals received for processing from the load cell; and adetachable chamber with humidifying media for humidification of the sampleenvironment confined within the chamber and separated frm the sample so asto avoid potential damaging effects of humidity on the sample or on thedevice. The device is useful for determining certain material propertiesof a sample.
