The MPI-507 is used for precise measurements of electrical installation parameters. Its sleek, compact and ergonomic design holds a wealth of measurement functions. Although it is one of the smallest multifunction meters on the market, it surprises one with its versatility, intuitive operation, and extended capabilities.
It has been designed for specialists in the installation and electrical industries, as well as for professional measuring engineers. Its main advantage is the quick measurement of fault loop impedance in circuits with RCD. It measures short-circuit loop parameters, insulation resistance, the resistance of protective and equalizing connections, earth resistance, as well as the testing of residual current devices (RCD) of type AC and A.
The functions are selected with a rotary switch. Additional parameters are set with buttons located on the housing interface. It is easy to use and priced very competitively. The device settings are saved automatically even when the battery is completely discharged. The backlit display and buttons make it suitable for use in low light. The large memory eliminates the need for taking notes during the measurements.
It is suitable for inspecting the safety of electrical systems in households and industrial facilities. Its housing is robust and weather-resistant with an IP67 rating. Bluetooth wireless communication allows easy transfer of data. Use Sonel Reports PLUS software to generate a report on measurements for electric shock protection. Saving the downloaded data to the simplest formats and printing is provided by free Sonel Reader software.
