Testing labs in Blaby

Universal Instrument Services (UIS) is one of the United Kingdom's most established and technically advanced independent calibration laboratories, founded in 1966 and headquartered in Blaby, Leicestershire. With more than five decades of continuous operation serving British industry, UIS holds full ISO/IEC 17025:2017 accreditation granted by the United Kingdom Accreditation Service (UKAS), confirming the technical competence and measurement traceability of its calibration activities across a comprehensive range of physical parameters. The laboratory additionally maintains ISO 9001:2015 Quality Management System certification, underpinning a structured framework that ensures all internal processes, service delivery procedures, and customer-facing activities are systematically monitored and subject to continual improvement. The core business of UIS is multi-parameter instrument calibration — the formal process of comparing measurement instruments and standards against nationally and internationally traceable reference standards, determining accuracy and issuing UKAS-endorsed calibration certificates. UIS covers electrical, dimensional, temperature, humidity, pressure, torque, and data-acquisition disciplines under a single UKAS-accredited schedule, making it a genuine one-stop calibration partner for organisations whose production, maintenance, research, or regulatory compliance programmes depend on verified instrumentation. This breadth of in-house accredited scope eliminates the cost and administrative burden of managing separate specialist suppliers for each measurement discipline. In the electrical and electronic measurement domain, UIS calibrates a wide variety of instruments including multimeters, DC bridges, counters, oscilloscopes, power supplies, watt meters, earth testers, and calibrators. PAT tester calibration is also offered, supporting industries that must regularly verify the accuracy of portable appliance testing equipment to demonstrate electrical safety compliance. Dimensional calibration at UIS is equally comprehensive, encompassing micrometers, depth gauges, plug gauges, screw gauges, ring gauges, vernier calipers, sine tables, engineer squares, and jigs and fixtures — services that are fundamental to manufacturing and quality-assurance environments where dimensional accuracy directly governs product conformance and tooling reliability. Temperature and humidity measurement represent core UKAS-accredited specialisms, covering thermocouples, thermometers, block calibrators, and humidity probes and sensors including models with integrated or remote displays, all calibrated against traceable national standards. Pressure parameter calibration spans pressure gauges, vacuum gauges, and manometers across a broad range of working pressures relevant to process, laboratory, and industrial environments. Torque tool calibration encompasses torque wrenches and torque drivers, supporting mechanical assembly operations and maintenance teams where verified fastener loading is a safety-critical or process-critical requirement. UIS also calibrates data loggers used across pharmaceutical, food storage, manufacturing, and environmental monitoring applications, as well as hand vane shears used in geotechnical soil-measurement contexts. A significant differentiator for UIS is its operation of fully UKAS ISO/IEC 17025:2017 accredited mobile calibration laboratories, which bring the same rigorous accredited standard directly to the customer's premises. These temperature-controlled mobile laboratory units have been part of the UIS capability since 2003, and are fully equipped to perform accredited multi-parameter calibrations on-site, eliminating instrument downtime associated with transit and allowing large, fixed, or integrated equipment to remain in situ. This mobile service gives organisations in pharmaceutical manufacturing, food processing, utilities, healthcare, and general industry the flexibility to maintain full traceability and regulatory compliance without interrupting operational continuity. UIS provides a complete instrument inventory management solution alongside its calibration services, giving customers a structured, auditable approach to tracking calibration due-dates, calibration histories, and compliance documentation across their entire instrument estate. For parameters that fall outside the laboratory's own in-house UKAS-accredited scope, UIS actively manages subcontract relationships with a network of specialist calibration laboratories, enabling clients to consolidate all calibration requirements through a single managed service agreement. A complimentary collection and delivery service is available across most of the United Kingdom using specially equipped vans, with all instruments fully insured from collection through to return — an arrangement that makes the service both logistically convenient and low-risk for clients whose precision instrumentation represents significant capital investment. Organisations across a broad cross-section of UK sectors depend on UIS for UKAS-traceable calibration, including pharmaceutical and medical device manufacturers, food and beverage processors, electronics and electrical equipment assemblers, construction and geotechnical firms, environmental monitoring bodies, and general engineering and manufacturing facilities. The combination of nearly sixty years of calibration expertise, UKAS accreditation across multiple measurement parameters, ISO 9001:2015 quality management, UKAS-accredited mobile on-site laboratory capability, and integrated inventory management positions Universal Instrument Services as a highly credible and comprehensive calibration partner capable of meeting demanding regulatory, contractual, and quality-system requirements throughout the United Kingdom.
