Why engineers choose the Inspector V4
Permanent, not a campaign
It stays on the asset and records every event, including the one that happens the week after a portable analyzer would have been removed.
Earth measured, not assumed
Earth current (0–10 A) and earth resistance (0–200 Ω) are measured by the same unit, so a grounding fault shows up next to the voltage event it causes.
Built for hospital sites
The power supply is certified to IEC 60601-1, the medical electrical equipment standard — the reason it is installed next to MRI, CT and X-ray systems.
Evidence, not a theory
Every event stores five cycles of waveform before and after, so you can see what the supply did, not just that something happened.

- UPS input and output verification
- Motors, pumps and VFDs in production
- Data centres and telecom rooms
How it is priced
Inspector is quoted per project rather than from a price list, because the cost depends on the model, the number of measurement points, the sensors and clamps you need, and whether you want the cloud dashboard and alerts. Tell an engineer what you need to measure and you get a quote for that configuration. For how analyzers are priced across the market, read what a power quality analyzer costs.
Made in Egypt, supported worldwide
Inspector is designed and built by PowerWadi in Sheikh Zayed, Giza. Customers in Egypt buy directly from the manufacturer, with engineers in the same time zone; elsewhere it is supplied directly or through distribution partners. More than 4,000 critical assets are monitored in more than 30 countries.
