TESTEM GmbH is a reliable supplier of measurement data recording systems and devices. Our many years of experience, comprehensive expertise and goal-oriented approach to solutions have allowed us to manufacture high-quality devices and systems for recording and transmitting measurement data as well as for determining physical parameters in the sensor segment. Thus, we provide systems for fuel quantity measurement and closing force measurement as well as powerful telemetry systems, fuel injection monitoring systems and high-quality HF amplifiers. With our extensive knowledge, we have come to focus on areas such as contactless (radio) data transmission. For example, in the area of radio data transmission, we produce diversity receivers, wideband receivers and wideband transmitters that function as data transmitters. Additionally, we offer powerful measurement recording devices such as data loggers and single-stroke engines that are used to simulate different motor operating states.
