Application
The MPI-C recorders are used in the energy, chemical, pharmaceutical, food, metallurgical industries, manufacturing, laboratories, and wherever measurement values registration are required. They are mainly used for recording eg. temperature, humidity, pressure, flow and flow rates. Example of apllication: monitoring of steam produced in boiler (pressure, temperature, flow rates).
