What We Do

Experts in test and measurement

We are experts in test and measurement, with a primary focus on electrical power measurement.

It all began with very accurate phase measurement devices for Frequency Response Analysis. These fundamental principles have been expanded to power and many other applications.

By vertically-integrating the key-components:

  1. Hardware Design
  2. System Integration
  3. Calibration

We deliver a complete measurement solution, from the Device Under Test (DUT) to the displayed value.

Our Expertise

Test Equipment Design

Clipboard on desk contain documentation for design a custom test system.

At our core, we are hardware engineers. We started out in the labs and we understand the measurement that real engineers need to make. And appreciate the challenges of real-world measurements, not just the theory.

Our goal is to create products that get straight to results, without the need to think about measurement samples, tweaking code, or gluing together software environment.

Just connect and measure!

System Integration

Your projects are unique, testing standards are constantly evolving, and the result is testing systems are becoming ever more complex. Combining our products and accessories extends the performance to push to boundaries with voltage, current, bandwidth, and meet the latest demands, and navigate testing requirements. We work alongside: R&D departments, development, metrology and testing laboratories and universities to assemble a coherent system.

Calibration

Displaying a value is easy - the challenge is proving that it is right!

We have spent decades developing equipment, processes and facilities in order to traceably demonstrate our accuracy. Giving confidence in our new units, and maintaining them them as an authoritative source.

Our in-house lab is accredited to ISO17025, and we have worked with institutions include the National Physic Laboratory, and Oxford University to quantify our performance and design.
