Equally extensive as our product portfolio is also the variety of accessories for our test equipment. From housing via diagnostic equipment through to special constructions like tilt units, various solutions are possible.

TrueData spans a range of innovative diagnostic equipment, particularly developed for the characterization of test equipment. The centerpiece is the impedance spectrum analyzer TrueData-EIS. In combination with the electronic load modules TrueData-LOAD, efficient electrochemical diagnostic equipment can be realized. Moreover, additional options, like multi-channel adapters, a cyclic voltammetry mode or a multi-quadrant operation is integrable.

With our products belonging to the TrueXessory series, we provide in addition sophisticated test equipment, which is particularly customized for the ambitious test requirements of special constructions or cases of application. Hence, along with the Evaluator test systems, top-performing tools for characterization, model building and optimization are on hand.
