Multifunctional Electrical Installations Meter- Sonel MPI-507
An excellent small multitasker
The electrical installation parameters multifunction meter A special type of hand tool used for exact measurements of electrical installation parameters is the Sonel MPI-507. The meter hides a wide range of measurement operations inside its slim and small frame. This device’s incredibly convenient and ergonomic design, which makes it simple to carry and improves working comfort, is an added benefit.
One of the smallest multifunction meters on the market, the Sonel MPI-507 meter stuns with simple operation and broad possibilities. It is a multipurpose tool that is prepared to function under any circumstance. It was created for experts in the electrical and installation industries as well as for certified measuring engineers.
With this instrument it is possible to perform basic measurements of various types, including measurements of short-circuit loop parameters, insulation resistance, resistance of protective and equalising connections, earth resistance measurement, as well as testing of residual current devices (RCD) of type AC and A. Due to its compact form and favorable price, the meter will appeal especially to novice users. Its excellent working precision means that its advantages will also be appreciated by advanced measuring engineers.
