Ho so thuong hieu quoc te
Testomat is the online analyzer family from Gebrüder Heyl / Heyl Analysis Technologies, best known for automatic hardness and water-quality monitoring in treatment facilities.It is important where softeners, RO pretreatment, cooling circuits, boilers, and drinking-water installations need continuous residual-hardness or limit-value supervision.
Testomat's position in instrumentation and sensors is defined by product families such as Automatic hardness control, The Testomat Family › Testomat 2000, The Testomat Family › Testomat 2000 DUO and The Testomat Family › Testomat 2000 CAL.
The portfolio is best understood inside online water-quality measurement, process control, chemical dosing feedback, plant monitoring, and safety interlocks, where engineers compare the technology route, family boundaries, and duty fit before narrowing to individual models.Representative series on this page include Testomat EVO TH, Testomat 2000 and Testomat 2000 DUO.Engineers should compare measured parameter, range and accuracy, wetted materials, calibration workflow, and control-system communication.
