ADMET Inc.'s (Norwood, Mass.) new-generation materials testing system, MTESTQuattro, replaces the company's MTESTWindows system. The new system offers monotonic, cyclic and segmented testing profiles and, in addition to tension and compression tests, performs tests and reports data for creep, fatigue, friction, flexure, peel, relaxation, shear and tear tests. The device is designed for manual, electrohydraulic and electromechanical testing machines. It samples at rates up to 1 kHz, and it features new screen displays and new report writing and data handling capabilities. Its base configuration consists of load, crosshead position, axial strain, transverse strain and auxiliary input channels, with options for three additional auxiliary input channels and servo control. The system comes with a Windows XP/Vista PC-based application program and an external interface box. It offers unlimited calibration tables per analog channel and up to 10 calibration points per transducer, with piece-wise linear fit between points. Force and extensometer strain accuracy exceed ASTM E-4 and E-83 standards, respectively. Other features include an embedded 32-bit high-speed ARM processor for data acquisition and control. A digital PID (proportional integral derivative) filter allows for control of ramp and hold, sawtooth, sine, and square wave profiles. The base configuration price is $7,870.
