Application area
Multy-channel voltage meter-logger IR-1 Mendeleevets is designed for measuring and recording of parameters of ECP and stray currents.
Advantages:
- four measuring channels (see typical connection schemes);
- LCD display and keyboard for programming and visual control of measuring;
- two modes of measuring: manual and automatic;
- isolated channel for measuring current at 75 mV shunt;
- possibility to comment;
- shock-resistant and moisture proof case;
- convenient data processing.
