The Sefram MW9325 Multifunction Tester is a compact yet sophisticated electrical installation testing tool designed for professionals. Slotting neatly into a standard outlet without batteries, this pocket-sized device delivers powerful diagnostics, ranging from TRMS voltage measurement and RCD testing to earth resistance and harmonics analysis, all in compliance with IEC/EN 61557‑3 and ‑6 standards. Its durable CAT III 300 V rating, vivid TFT display, and lightweight construction make it an indispensable companion for electricians, engineers, and maintenance technicians.
Because it’s a powerhouse in your pocket. The MW9325 combines the functionality of a TRMS multimeter, socket tester, loop impedance checker, and harmonics analyser, all in a compact, battery-free form factor. It streamlines compliance testing with automatic RCD and non-tripping earth loop tests, delivers rich measurement insights via QR-code-generated smartphone reports, and stays powered long enough to capture post-disconnection readings (thanks to its supercapacitor technology), making inspections faster, safer, and easier.
Accurately tests voltage and wiring faults like phase‑neutral‑earth reversals.
Validates residual current device performance seamlessly.
Measures earth loop resistance in TT/TN systems without causing circuit disruption.
Detects grounding issues that compromise electrical safety.
Monitors power quality by measuring harmonics up to the 49th order and displaying total harmonic distortion.
Remains operational long enough post‑disconnection to record results, which are stored internally.
Generates comprehensive, digitised test reports via a smartphone for efficient documentation and record-keeping.
Ensures durable performance and enhanced portability in challenging field environments.
Offers sharp readability and effortless handling during prolonged use.
Adapts to varying mains voltages with robust insulation testing capability.
