Temperature Mapping Services
GxP Compliant temperature mapping solutions

TekTroniks provides ukas accredited mapping services for:

• Pharmaceutical & Healthcare: Fridges, freezers, incubators, cold rooms, and laboratories (in line with MHRA and GxP guidelines).

• Warehousing & Distribution: Large-scale storage facilities, loading bays, trailers, and cold chain vehicles (to meet GDP and GMP standards).

• Food Safety: Cold stores, freezers, production areas, and ambient storage (to meet BRC and HACCP requirements).

Our professional mapping service manages the entire process, from initial scope definition to final reporting and is designed to support your compliance lifecycle.

To meet the highest level of regulatory scrutiny, temperature mapping must be conducted to rigorous standards. Our service offers UKAS Accredited Temperature Mapping, providing a level of assurance that exceeds standard mapping services:

• Highest Assurance: The service is independently audited and certified by UKAS (United Kingdom Accreditation Service) to ISO/IEC 17025:2017 standards. This verifies the competence, impartiality, and consistent operation of our calibration and testing processes.

• Regulatory Acceptance: UKAS-accredited reports are recognized and accepted by all major regulatory bodies, including the MHRA, GMP, GDP, BRC, and FDA.

• Traceability and Uncertainty: Every report includes UKAS-calibrated sensors with full certificates and documented measurement uncertainty data, as required by ISO/IEC 17025.

We can also provide remote mapping, Similar to the UKAS mapping, we still manage the whole process. The difference is, we ship the equipment and you place the loggers yourself.

Temperature mapping is the process of measuring and recording temperature variations across a specific area, environment, or piece of equipment to ensure uniformity and compliance with required standards.

This technique is critical in industries like pharmaceuticals, warehousing, food storage, and manufacturing, where temperature control is essential for product safety, quality, and regulatory compliance.

In temperature-sensitive environments such as cold storage warehousing, product fridges, or production areas, small temperature deviations can lead to compromised product quality or even loss.

Temperature mapping identifies these variations by using strategically placed sensors over a set period, gathering real-time data on temperature fluctuations. The goal is to detect "hot spots" or "cold spots" that may affect the integrity of the stored products.

This process helps verify that heating, ventilation, and air conditioning (HVAC) systems, refrigeration units, or other environmental controls are functioning as expected. It's also used during the validation phase of new equipment or facilities and as part of routine monitoring to ensure consistent conditions over time.

Temperature mapping results are documented and analysed to make necessary adjustments, such as relocating temperature-sensitive products, improving insulation, or reconfiguring airflow. Regulatory agencies like the MHRA, BRC, FDA and WHO require temperature mapping to ensure products are stored in appropriate conditions, making it an essential step in industries where maintaining temperature-controlled environments is critical for safety and efficacy.

Unlike many companies offering temperature mapping Tek Tronks are UKAS accredited to complete studies to ISO 17025.  Click here to see our UKAS accreditation schedule.

We prove your environment stays within required limits by placing calibrated sensors throughout the space, recording data, and identifying hot or cold spots.

This evidence satisfies auditors and protects your products.

We map warehouses, cold rooms, fridges, freezers, incubators, and temperature‑controlled vehicles.

If you store or transport temperature‑sensitive goods, mapping is essential for compliance.

Mapping is a short‑term study to prove uniformity across a space. Monitoring is continuous measurement at fixed points.

Mapping validates, monitoring maintains.

We map new buildings, when major changes have taken place, and/or at regular intervals set by your quality system or regulator.

Many clients repeat mapping annually, at winter and summer, to remain audit‑ready.

We work to MHRA, GDP, GMP, BRC, FDA, and ISO/IEC 17025:2017. Our UKAS‑accredited service meets the highest recognised standard.

The purpose of temperature mapping is to assess and document the temperature distribution within controlled environments, such as a storage area, refrigeration units, warehouses, transport vehicle.

The process is used to ensure that the entire space maintains uniform temperatures within the required limits to safeguard the quality and safety of temperature-sensitive products like food, pharmaceuticals, and vaccines.

Temperature mapping helps identify hot and cold spots in the environment where temperature deviations may occur. These variations can result from factors like air circulation, proximity to doors, or the positioning of cooling units. Understanding these fluctuations is essential for ensuring that all parts of the environment stay within safe temperature limits, preventing product degradation, spoilage, or contamination.

One of the key purposes of temperature mapping is to ensure regulatory compliance with industry standards and guidelines, such as those outlined by HACCP, MHRA, FDA, or Good Distribution Practices (GDP). Many regulations require businesses to prove that their storage and transport environments are suitable for keeping products at specified temperatures.

Furthermore, temperature mapping aids in the design and validation of temperature monitoring systems. It helps determine the optimal placement of sensors to provide accurate real-time temperature data from critical areas, improving the effectiveness of monitoring.

Overall, temperature mapping ensures that controlled environments are reliable and consistent, minimizing risks to product quality and safety, while ensuring compliance with regulations and enhancing operational efficiency.

To meet the strictest requirements our temperature mapping processes are UKAS 17025 accredited.

The key difference between UKAS accredited temperature mapping and UKAS traceable temperature mapping lies in the level of assurance and certification involved.

 UKAS Accredited Temperature Mapping: In this process, the temperature mapping is conducted by an organization accredited by UKAS (United Kingdom Accreditation Service), such as Tek Troniks.

UKAS accreditation ensures that we operate in accordance with internationally recognized standards (ISO/IEC 17025 for testing and calibration laboratories). This provides the highest level of confidence in the accuracy, reliability, and competence of the service we provide.

The results from a UKAS-accredited temperature mapping service are generally required to show regulatory compliance, particularly in industries such as food warehousing, pharmaceuticals and healthcare.

UKAS Traceable Temperature Mapping: In contrast, UKAS traceable temperature mapping involves using equipment that has been calibrated against standards that are traceable to UKAS, but the actual temperature sensors and mapping process may not be conducted by an accredited organization.

While this ensures that the measurements are based on UKAS-traceable instruments, the overall process does not undergo the same stringent quality assurance as fully accredited mapping. It is often seen as more cost-effective mapping, but this must be weighed against the lack of process integrity by not being independently audited.

In summary, UKAS accredited mapping offers full certification and regulatory confidence, while UKAS traceable mapping focuses on using traceable instruments without the full accreditation process.
