TT Instruments

TT Instruments® is an ISO 9001 certified UK company supplying high-quality used test and measurement equipment at competitive prices to customers worldwide. From our base in Blackburn, we specialise in telecoms and fibre optic test equipment — including OTDRs, OSAs, fusion splicers, DSL cable testers, CATV and Ethernet/network testers. We also stock a broad range of laboratory, electronic and RF test equipment, from oscilloscopes and probes to signal and spectrum analysers. Alongside global sales, we now offer flexible rental options for our telecommunications, laboratory and electronic test equipment — exclusively to our UK customers. This gives businesses the freedom to access precision instruments when needed, without the upfront costs of ownership. Sustainability sits at the core of what we do. We actively buy unwanted, surplus or end-of-life test equipment at fair prices. By reusing, refurbishing or responsibly recycling, we help prevent valuable equipment from going to landfill and support a circular economy in our industry. Over the years, we’ve earned a reputation for exceptional service, reliable shipping and genuine technical expertise. Many of our customers return to us again and again, confident that they’ll receive honest advice, trusted equipment and support that exceeds expectations.
