SNA-L70 is an innovative instrument for measurement of the electrical parameters. It is particularly suitable for consumption analysis and control, with an excellent quality/price ratio.
For the version with Rogowski coils (RGW model), connections are very quick and easy, very useful for retrofitting applications on existing switchboards or for energy audit.
SNA-L70 is the ideal instrument to establish the measurement points on the plant.
The instrument can communicate through the RS-485 serial port by MODBUS RTU/ASCII protocol.
