GLMU 400MP-SW, Conductivity Measuring Transducer incl. 4-Pole Measuring Cell

Galvanically isolated conductivity transmitter with microprocessor control and extended functionality. Alternatively, salinity (salt content of seawater), TDS  or specific resistance can be outputted as output signal.
Cheap conductivity measurements in drinking water, seawater, process water and sewage.

Application area:

• Higher saline concentrations (e.g. brine measuring)
• Measurements in polluted solutions / waste water
• Control of neutralization
• Heavily polluted liquids

 

Properties:

• High-quality conductivity measuring cell, insensitive to dirt
• Output signal freely scalable
• Adjustable cell constant
• Selectable temperature compensation mode
• On site display for the conductivity or temperature
• Exchangeable unit labels
