The accredited range covers 0.025 mL/min to 13,000 L/min, accommodating ultra-low flow laboratory instruments through to high-flow industrial equipment. Calibration is performed using air, argon, carbon dioxide, helium, oxygen and nitrogen. Results are specific to the gas used. If a meter calibrated on air is to be used with a different gas, a gas conversion factor must be applied. Instruments calibrated: variable area flow meters (rotameters), laminar flow elements, mass flow meters and controllers, dry gas meters, wet gas meters, Coriolis mass flow meters, primary piston meters, bubble generators, orifice plates, vortex shedding meters. Typical manufacturers serviced: Aalborg, Alicat Scientific, BIOS, Brooks Instruments, Cole-Parmer, Endress+Hauser, Honeywell, MKS Instruments, Omega, Sierra Instruments, Bronkhorst, TSI. In regulated industries, UKAS accreditation is the required standard for externally calibrated gas flow instruments. ISO 9001:2015 and GMP guidelines require measurement traceability. Annual calibration is standard in pharmaceutical and environmental applications; pre- and post-campaign calibration is common in occupational hygiene. --- ## Air Velocity Calibration URL: https://labcal.co.uk/air-velocity-calibration/ Labcal provides UKAS-accredited air velocity calibration under UKAS Lab 0625, ISO/IEC 17025:2017. Calibration is performed in a controlled wind tunnel environment. The accredited range covers 0.1 to 70 m/s. Labcal operates multiple wind tunnels, enabling accommodation of a wide range of instrument types and sizes. Optional Laser Doppler Anemometer (LDA) calibration is available for applications requiring lower measurement uncertainty than can be achieved with conventional wind tunnel methods. LDA is a non-contact optical technique and is used for reference instruments and research applications. Instruments calibrated: hot wire anemometers, vane anemometers, cup anemometers, pitot static tubes, thermal velocity probes, ultrasonic anemometers. Applications requiring air velocity calibration include: fume cupboard face velocity testing (COSHH compliance), cleanroom and HVAC commissioning and verification, asbestos enclosure pressure and velocity testing, pharmaceutical cleanroom environmental monitoring, fire and smoke ventilation verification, and aerodynamic research. Air velocity calibration with UKAS accreditation is the expected standard in most of these applications, particularly cleanroom qualification and pharmaceutical environments where EU GMP Annex 1 or ISO 14644 compliance is required. --- ## Pressure Calibration URL: https://labcal.co.uk/pressure-calibration/ Labcal provides UKAS-accredited pressure calibration under UKAS Lab 0625, ISO/IEC 17025:2017. The accredited range covers 0 to 1,400 bar (0 to 140 MPa, 0 to 20,000 psi) for general pressure instruments. Labcal also holds specialist accreditation for low and differential pressure calibration from 0 to 9,000 Pa, which requires dedicated reference equipment not available at most UKAS laboratories. Labcal calibrates gauge, absolute and differential pressure instruments. Gauge pressure is measured relative to atmospheric pressure. Absolute pressure is measured relative to a perfect vacuum. Differential pressure measures the difference between two pressures. If an instrument is found to be outside tolerance, the as-found condition is recorded on the certificate. Where adjustment is technically possible, Labcal can perform adjustment and re-calibrate to confirm the as-left condition. Instruments calibrated: pressure gauges, pressure transducers, pressure transmitters, manometers, digital pressure indicators, low-pressure instruments, barometers. Typical manufacturers serviced: WIKA, Druck, Fluke, Omega, Kistler, Honeywell, Emerson. --- ## Temperature Calibration URL: https://labcal.co.uk/temperature-calibration/ Labcal provides UKAS-accredited temperature calibration under UKAS Lab 0625, ISO/IEC 17025:2017. The accredited range covers -30°C to +140°C. Instruments calibrated: digital thermometers, temperature probes, RTDs (resistance temperature detectors), thermocouples, data loggers, temperature transmitters, temperature controllers. ISO 9001:2015 Clause 7.1.5 requires measurement equipment to be calibrated against standards traceable to national or international measurement standards. UKAS accreditation is the recognised route to demonstrating this traceability. In pharmaceutical GMP environments, calibration intervals for critical temperature instruments are typically annual. For food production and cold chain, calibration is often required more frequently based on the criticality of the measurement. Typical manufacturers serviced: Testo, Fluke, Comark, Hanna Instruments, Omega, Endress+Hauser, Vaisala. --- ## Humidity Calibration URL: https://labcal.co.uk/humidity-calibration/ Labcal provides UKAS-accredited humidity calibration under UKAS Lab 0625, ISO/IEC 17025:2017. The accredited range covers 10% to 90% relative humidity (RH) at temperatures from +15°C to +40°C, and 15% to 90% RH between +10°C and +15°C. Temperature probes in air can be calibrated in environmental chambers from -5°C to +60°C (temperature measurement only). Humidity calibration requires the instrument to be exposed to a controlled environment with a stable, known relative humidity. Labcal uses environmental chambers where both temperature and humidity are held at defined reference conditions using traceable standards. Instruments calibrated: hygrometers, humidity transmitters, combined temperature and humidity probes, dew point sensors, environmental data loggers, relative humidity controllers. Typical manufacturers serviced: Rotronic, Testo, Vaisala, Michell Instruments, TSI Instruments, Fluke. In pharmaceutical manufacturing environments, humidity is a critical GMP parameter. Annual calibration is common. For HVAC and cleanroom applications, calibration is typically aligned with the facility's environmental monitoring schedule. --- ## Liquid Flow Calibration URL: https://labcal.co.uk/liquid-flow-calibration/ Labcal provides UKAS-accredited liquid flow calibration under UKAS Lab 0625, ISO/IEC 17025:2017. The accredited range covers 0.5 mL/min to 450 L/min, calibrated using water as the reference liquid. Water calibration is appropriate for instruments used with other low-viscosity liquids of similar density. For liquids with significantly different properties, a conversion factor may be required. Labcal calibrates both volumetric flow instruments (measuring volume per unit time) and mass flow instruments (measuring mass per unit time, independent of density variations). Coriolis mass flow meters are calibrated for both measurement types within the UKAS scope. Instruments calibrated: turbine flow meters, electromagnetic flow meters, Coriolis mass flow meters, paddle wheel flow meters, positive displacement meters, ultrasonic flow meters. Annual calibration is standard in pharmaceutical production and food manufacturing. Calibration intervals should be based on instrument stability, measurement criticality, and historical performance data. --- ## Pharmaceutical & Life Sciences Calibration URL: https://labcal.co.uk/pharmaceutical-calibration/ Labcal provides UKAS-accredited calibration for pharmaceutical manufacturers, contract development and manufacturing organisations (CDMOs), cold chain operators, and life sciences laboratories.

Labcal operates as a white-label subcontract partner for laboratories requiring additional UKAS scope coverage. --- ## Frequently Asked Questions **What is UKAS calibration?** UKAS calibration means an instrument has been calibrated by a laboratory independently assessed by the United Kingdom Accreditation Service (UKAS) to ISO/IEC 17025:2017. Unlike simply traceable calibration, UKAS accreditation involves a rigorous technical assessment of the laboratory itself, its equipment, staff competence and measurement processes. Certificates from UKAS-accredited laboratories are recognised in regulated industries for audit compliance. **What is the difference between traceable and UKAS-accredited calibration?** Traceable calibration means the calibration chain can be traced back to national measurement standards, but provides no guarantee about the quality of the laboratory performing the calibration. UKAS accreditation adds an independent assessment verifying the laboratory meets ISO/IEC 17025:2017 requirements. For regulated industries, most audit frameworks specifically require UKAS or equivalent accreditation, not simply traceability. **Do I need UKAS calibration for ISO 9001 compliance?** ISO 9001:2015 Clause 7.1.5 requires measurement equipment to be calibrated against standards traceable to national or international standards. UKAS accreditation is the recognised route to demonstrating this traceability to certification bodies. Most ISO 9001 auditors and registrars expect UKAS-accredited certificates for externally calibrated instruments. **Can I switch to Labcal from my current calibration provider?** Yes. Send the most recent calibration certificate and Labcal will quote a like-for-like service matching the existing scope, parameters and tolerances promptly. No switching cost, no retraining for quality teams, no changes to audit documentation. **How long does calibration take?** Average turnaround is7 working days from receipt at the Lymington laboratory. A 3-day fast-track service is available by arrangement. Turnaround begins when instruments arrive at the laboratory.
