MAC 100 – Version with aluminium housing

The MAC 100 is a transmitter for liquid analytical measurements with sensors of the OPTISENS pH, ORP, COND, IND, ODO, ADO, TUR and CL sensor series. The transmitter can be installed with up to two sensors plus temperature input. Due to its robust aluminium housing, it is perfectly suited for wall-mount installation even in the harshest ambient conditions. Its optional stainless steel version is the perfect fit for all applications with hygienic requirements.

The MAC 100 features three analogue (4…20 mA) and relay outputs. It adheres to the same General Device Concept (GDC) as the KROHNE flow and level converters for rapid commissioning, reduced training times and standardisation.
