Data loggers of the GSR and PSR family measure and record various quantities such as pressure, level, flow, temperature, conductivity, etc. The voltage supply adapts to the application point. It takes place via mains electricity, with a battery or solar energy. Depending on the design, they can be compact or have dislocated electronics. Data transmission can be local, via network or remote.
Conductivity meters are used in monitoring water resources, lakes or rivers, for water quality control (soft water) in hot water systems.
Depending on the type of installation, these can be “submersible/underwater” or “dry mount” versions.
