WHY CHOOSE VFE’s UKAS ACCREDITED* CALIBRATIONS
Calibrate your equipment to globally recognised standards and instil buyer confidence in the quality, safety and reliability of your products and services.
VFE engineers can carry out UKAS accredited calibrations (UKAS Accredited Calibration Laboratory No.4338) on a wide range of heat treatment equipment.
In general, calibration confers benefits such as increased energy efficiencies, higher productivity, greater reliability, optimised equipment utilisation and quality assurance.
On top of these benefits, the UKAS certification ensures that our customers can rely on our results completely and with confidence.
Choosing VFE’s UKAS accredited calibration provides you with an impartial measure of your heat treatment equipment’s best measurement capabilities while helping you to build consumer trust and confidence in the quality of your products and services.

The United Kingdom Accreditation Services (UKAS) was first established in 1995 as the sole UK body recognised by the government to assess the conformity of UK organisations against internationally recognised standards.
Today, it achieves this by accrediting those bodies it certifies as conforming to those standards. The consulting process is rigorous, looking at everything from a company’s management to its policies, procedures and people to ensure compliance.
As the sole national accreditation body for certification, testing, inspection and calibration in the UK, UKAS accredited organisations are assured to operate to the highest possible conformity standards. UKAS also provides mutual recognition through international groups such as EA, IAF, ILAC enabling accredited organisations to provide their services internationally.
Accreditation is then reviewed on an annual basis to maintain the high standards and robust best practices for which UKAS accredited organisations are renowned, attesting to the quality and the culture of those organisations achieving accreditation.
ACCREDITED RESULTS YOU CAN TRUST
Our UKAS accredited calibrations (UKAS Accredited Calibration Laboratory No.4338) covers both calibration at our laboratory and on-site calibrations.
Our UKAS accredited calibrations provide results that you can rely on. Our experienced team can also be your impartial guide to decisions about risk and conformity, helping you to comply with industry-specific standards like AMS2750.
If you haven’t worked with us before, this accreditation should give you the confidence that we have the competence required to deliver your calibrations.

OUR CALIBRATION SERVICES
Calibration of a device that takes a signal reading from a sensor and converts it into a measurement for control, recording or monitoring using a series of known simulated inputs.
The comparison of the output or indication of a device used to measure pressure with that of another pressure measurement device, or pressure measurement standard.
This can be gauge pressure (referenced to atmospheric pressure), differential pressure (between two variable pressure levels) or absolute pressure (referenced to a ‘perfect’ vacuum). Absolute pressure measurements can also be presented as altitude measurements for avionic devices.
The calibration of the output or indication of any device used in a system that is capable of measuring pressure below about 1x10−2 mbar down to 1x10-5 mbar absolute.
The unit under test is a temperature sensor such as a thermocouple or a temperature measurement system such as a temperature indicator or portable data logger. The indicated temperature is compared to the reference measurement.
Typically performed in a laboratory, the sensor to be calibrated is immersed in a stable temperature environment such as a dry metal block, an oil bath or a furnace.
The reference temperature for comparison is determined by a secondary standard thermocouple or thermometer.
Generally performed to assure the accuracy of control and recording instruments in each control zone in furnaces, ovens, etc.
An independent system consisting of a recording instrument and thermocouple sensor(s) is used to monitor and record data during a typical heating cycle while comparing the readings with the resident control system.
The purpose of the test is to detect and quantify any deviation in the complete furnace measuring systems’ accuracy to determine if they are within acceptable limits.
Temperature Uniformity Survey (TUS), is the process of mapping the temperature variance throughout the working volume of a furnace, autoclave or oven.
Pyrometry standards such as AMS2750 and many other customer requirements set the tolerances for the equipment performance to ensure it is capable of processing parts as intended.
The method and frequency must comply with the requirements, not just the results.
Relative Humidity (%rh) is the measurement of how saturated a gas (typically air) is with water relative to the maximum saturation possible for the given temperature and pressure.
Device output or indication can be compared to reference measurements made in-situ or they can have a controlled and stable relative humidity applied in a chamber or with a test standard. The temperature measurement is also critical to the accuracy of results.
Measurement and control of this can be critical in pharmaceutical, food, electronics and materials handling and manufacturing.
It is important for many different thermal processes that accurate measurement of elapsed time takes place. This is true for cycles run in furnaces, autoclaves and other similar equipment.
We have reference equipment and procedures to also calibrate parameters including dimensional (length, depth), mass, flow, frequency, torque, pH, conductivity, viscosity.
