At Telonic Instruments Ltd we believe precision, performance and partnership define excellence. For over 50 years we have served the UK’s electronics, automotive, aerospace, education, manufacturing, research and development communities by delivering high-quality instrumentation, power supplies and support you can depend on. Our ISO 9001:2015 accreditation underpins our commitment to consistent, reliable service.

From our headquarters in the UK, we specialise in test instruments and high-performance programmable AC and DC power supplies supplied by globally-renowned manufacturers. Whether you are looking for frequency converters, bench DC supplies, regenerative bidirectional systems or sophisticated measurement equipment, we offer solutions from brands including Kikusui, Delta Elektronika, Lab-Power, ZES Zimmer, Rigol, Siglent, Brymen, Danisense, Tekbox, Graphtec, Sensepeek, Microtest and JBC.

What sets us apart is not just the product range, but the deep understanding of how it will be used. Every customer has unique needs: a research laboratory may require ultra-precise power supplies with full programmability, while a manufacturing test station might demand robust instruments with fast turnaround calibration and rental flexibility. We combine technical expertise with commercial agility, offering sales, service, calibration and hire options across the UK. With next-day UK delivery and a price-match guarantee, we ensure you can stay ahead in fast-moving projects.

Our rental service addresses a critical need in many environments: when you are under time pressure, or require equipment for a short-term project, our flexible rental options ensure you have the right kit without the long-term commitment. Meanwhile, our calibration and service support give you full confidence in your measurement chain, backed by our longstanding relationships and in-house expertise.

We understand the evolving demands of modern engineering: power-electronic test setups, renewable-energy systems, electric-vehicle infrastructure, aerospace avionics and advanced measurement systems all bring tighter tolerances, higher bandwidths and greater reliability requirements. With a carefully curated product portfolio and responsive specialist team, we are ready to support these emerging challenges.

At the heart of Telonic Instruments is a commitment: to act as your technical partner, not simply supplier. We will take the time to understand your application, advise on the most appropriate instrument, and ensure you get the best value from your investment. Whether you are upgrading equipment, scaling production, validating designs or simply looking to hire for a short-term need, we are here to support you every step of the way.
