Calibration within the CTS Group
Our calibration services are delivered through CTS Calibrations, a specialist business operating as an extension of CTS within the Phenna Group.
This dedicated focus allows calibration to support a wide range of industries while maintaining the technical rigour expected in regulated and safety-critical environments.
CTS Calibrations builds on our long-standing experience in measurement, testing, and assurance, with services designed to meet both operational needs and formal compliance.
The Role of Calibration in Regulated Industries
Accurate measurement underpins safe decisions, compliant processes, and reliable outcomes. In regulated sectors, organisations depend on equipment to produce results they can trust, whether to inform product performance, safety checks, or environmental controls.
When equipment is first put into use, it operates within a defined tolerance. Over time, wear, handling, and operating conditions can cause measurement accuracy to drift beyond the original tolerance, increasing the risk of error, inconsistent results, or non-compliance.
Calibration services check equipment against known standards to identify deviations and verify accuracy. Calibrating equipment to correct tolerances helps organisations maintain confidence in their measurements and meet industry and regulatory requirements.
Our Calibration Services
Our full range of calibration testing solutions is available through CTS Calibrations, covering commonly used measurement equipment across multiple disciplines. Calibration services are delivered through accredited laboratories and on-site when required.
Dimensional calibration
Dimensional calibration ensures the accuracy of equipment used to measure length, thickness, diameter, and geometry, such as gauges and levels. Commonly used in manufacturing, engineering, construction, and inspection environments.
Electrical calibration
Electrical calibration applies to equipment used to measure, monitor, and test electrical systems, including safety testing and diagnostic instruments. Used across manufacturing, facilities, utilities, technical maintenance, and other settings.
Pressure calibration
Pressure calibration confirms the reliability of digital and analogue equipment used to measure gas or liquid pressure in systems and processes. Typically required in industrial processing, energy, automotive, aerospace, and utilities environments.
Force calibration
Force calibration services check equipment that measures applied load or force, such as gauges and load-measuring instruments. Used across a wide range of industries where force measurement plays a key role in testing and production.
Torque calibration
Torque calibration verifies the accuracy of equipment used to apply or measure rotational force during assembly or maintenance. Common in manufacturing, automotive, aerospace, and mechanical engineering environments.
Temperature calibration
Temperature calibration applies to equipment used to measure or record temperature, from process monitoring to environmental control. Used widely in healthcare, food production, manufacturing, laboratories, and environmental monitoring.
Mass calibration
Mass calibration ensures the reliability of weighing equipment, such as balances and scales, used to measure material, product, or sample mass. Essential for laboratories, manufacturing, pharmaceuticals, food production, and research settings.
On-site calibration
On-site calibration services provide calibration at the customer’s location where equipment cannot be easily transported, or downtime must be minimised. This supports continuity while maintaining measurement assurance.
Additional calibration services
In addition to core calibration disciplines, CTS Calibrations offers calibration testing solutions for a wide range of specialist and application-specific equipment. These services support organisations that rely on less common or highly specific measurements as part of their operations.
Additional calibration services include areas such as humidity, surface and coating measurement, chemical and conductivity measurement, and instrument-specific calibration. Technical advice and assistance are available to help determine appropriate calibration approaches where requirements are less standard.
When Calibration Services are Typically Required
Calibration services are commonly needed when organisations:
- Operate measurement or test equipment as part of regulated processes
- Maintain in-house laboratories or site testing capability
- Prepare for audits, accreditation, or compliance reviews
- Need documented traceability to recognised standards
These requirements apply across many sectors, from construction and infrastructure to manufacturing, aerospace, automotive, healthcare, and environmental services.
Ongoing Assurance for CTS Clients
Calibration services provided through CTS Calibrations reflect the same commitment to quality, reliability, and responsive support that CTS clients expect. With a focus on precision and consistency, we continue to deliver calibration testing solutions you can rely on.
Frequently Asked Questions
What is calibration?
Calibration is the process of comparing an instrument’s measurements against a known standard. The results can confirm accuracy or identify deviations, which are documented on a calibration certificate. When equipment is out of tolerance, calibration services may also include adjusting the instrument to ensure it meets required specifications.
Why is calibration important?
Calibration is essential because it ensures that measurement equipment gives accurate and reliable results. Accurate measurements are critical for making informed decisions, maintaining product quality, meeting regulatory requirements, and keeping processes safe and consistent.
What is the difference between UKAS calibration and traceable calibration?
UKAS calibration is performed by a laboratory accredited to ISO/IEC 17025, under a system assessed for technical competence and consistency (UKAS calibration may include traceable calibration). Standard traceable calibration confirms linkage to recognised standards, but is not always carried out under UKAS accreditation.
