TetraTec Instruments GmbH develops, produces and sells sensors, measuring and control systems as well as test and calibration equipment for pressure, pressure flow and pressure tightness of air and fumes. Based on self-developed modular software, hardware and sensors for pressure, humidity and pressure flow, the offered measuring and control devices are suitable for the manufacturing environment as well as laboratories. Together with special machine construction partners, measuring and testing machines based on standalone measuring systems are realized. The company also operates a DKD-accredited calibration laboratory (DKD-K-22301) for volume and mass flow of flowing fumes and air. The company emerged in 2002 from the merger of TetraTec Software and Engineering GmbH and EP Instruments Messtechnik + Kalibrierung GmbH. The formal merger was the result of many years of cooperation between the two companies in the development and application of electronics, sensors, measuring and control devices for pressure, pressure flow and leak tightness. The devices and calibration services have a broad customer base, from the instrument manufacturer to the manufacturing industry. Main customers for the automated calibration and production testing systems are the automotive and automotive supply industry as well as medical technology and heating technology.
