Why engineers choose the Portable Inspector V4
Not a cut-down device
Same processor, same measurement accuracy, same event capture and the same six-hour battery as the permanent Inspector V4.
Built for the survey
Connect it, read live values on the 7-inch screen, leave it for the campaign and export the report as PDF, CSV or JSON.
Before you buy the fix
Prove whether the problem is the supply, the load or the earth before you pay for filters, a bigger UPS or a new transformer.
Upgrade path
If the survey shows a recurring problem, the same measurements continue on a permanent Inspector V4 with no change in method.

Where it is used
- Power quality audits and site surveys
- Checking a site before a new load is connected
- Investigating unexplained trips and stops
- Commissioning and acceptance tests
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.
