Testomat: hardness controller

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: hardness controller'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.

How to choose Testomat: hardness controller Instrumentation & Sensors

This section answers two questions: which main product families Testomat: hardness controller offers, and which parameters to compare before choosing a specific model.

Step 1: Choose a product family by application

The main families shown on this page are Automatic hardness control and The Testomat Family. Start with the treatment objective, equipment format, and operating duty, then use the model index below to compare exact specifications.

Step 2: Confirm the model by key parameters

After choosing a product family, compare measurement parameter, sample condition, signal integration, and maintenance frequency. Replacement projects should also verify installation or loading conditions, interfaces, and compatibility with the existing system; new projects should consider operating practice, maintenance, and spare-parts or consumables availability.
