|Conductivity Transmitter incl. Measuring Cell
● On-site display for conductivity and temperature
● Output signals freely scalable
● Type of temperature compensation selectable
The GLMU is suited for drinking water and waterbodies monitoring, for applications in fish farming and aquaristics, for measurements in polluted solutions and waste waters as well as for neutralization control.
The 4-pole measuring cell of the GLMU-400-MP is applicable for higher salt concentration, because its particularly insensitive to dirt.
The GLMU has an on-site display for conductivity and temperature. The output signal is freely scalable and the temperature compensation type can be selected.
