Amperis Products S.L. is a company based in Lugo (Spain) that has specialised since 2007 in instrumentation for testing, measuring and diagnosing substations and electrical installations. We work with utilities, industry, engineering firms and maintenance contractors who need to measure well and decide on data.
We do not sell a catalogue: we sell the right measurement solution for each problem. That is why the person handling your enquiry is an engineer, not a salesperson.
A complete range for the whole life of the installation
The equipment we offer is top-of-the-range within each family, and when the instrument you need does not exist, we find the combination that solves the test.
Engineers who guide you through the purchase
Choosing test equipment is a technical decision. A mistake is paid for with an instrument that does not cover the voltage, the current or the standard you need.
Before you buy
We analyse your application: asset type, voltage, test standard and field conditions. We propose the instrument that meets the need, not the most expensive one. If a simpler unit will do, we say so.
On delivery
Configuration, commissioning and training in the use of the equipment, on your premises or remotely, with the test procedures you are going to apply.
Afterwards
Technical support, calibration, repair and updates. We go through your first results with you if you need it.
Prefer to find your own way? The battery, circuit breaker, transformer and camera product pages include guided selectors, and the engineering calculators give you ready-to-use test calculations.
How we work
- Technical reply on the same working day.
- Quotations with reasoned alternatives, not a single price.
- Equipment with traceable calibration and documentation in your language where available.
- One contact person for the whole project.

Do you handle calibration and repair?
Yes. We manage traceable calibration, repair and updates for the equipment we supply.
