What is the Sonel MPI-540 Multifunction Installation Tester?
The Sonel MPI-540 is an advanced multifunction electrical installation tester designed for UK electricians, commissioning engineers and industrial maintenance technicians who need a single instrument for full installation testing, power quality checks and safety verification. With a large 7" touchscreen, automated test sequences and built-in power quality logging, it streamlines certification, troubleshooting and periodic inspection work across domestic, commercial and industrial sites.
How does the MPI-540 stand out in everyday electrical testing?
Whether you’re completing EICR inspections, verifying protection systems or diagnosing supply issues, the MPI-540 brings installation testing and power analysis into one device. Auto-tests, RCD checks, insulation testing and earthing measurements are handled quickly, while its three-phase power quality recorder captures voltage, current, harmonics and THD for deeper diagnostics. For electricians who need accuracy and efficiency on site, the MPI-540 delivers both.
