Introducing

Warehouse Mapping

Warehouse Mapping Services

Withnell Sensors are temperature and humidity specialists, we provide specialised warehouse mapping services. We help you deliver operational, regulatory and quality control requirements and follow WHO & ISPE mapping guidelines.

We distribute temperature and humidity monitoring devices from a number of the world’s leading manufacturers, as well as high quality temperature-controlled chambers, medical fridges and more. We also have our own UKAS accredited calibration laboratory and offer temperature mapping services. Our engineers are highly experienced, and can offer mapping services for any required environment- from fridges to warehouses. We use all of our own equipment, so can not only offer the service but all the products and support needed for a project. As temperature and humidity experts we can offer advice and support, hire equipment for you to complete your own warehouse mapping project or manage the task from survey through to final report. 


What we offer

We have a range of mapping services that can be tailored to suit your project requirements, saving you time and delivering cost effective but necessary support. All of the mapping equipment we use is maintained with a UKAS accredited calibration and we hold an extensive range of loggers in stock to ensure that we have enough equipment to support the largest warehouse mapping projects.

Compliance breeze

We ensure compliance for a number of industries, with Laboratories, Healthcare & Pharmaceutical companies MHRA and GxP guidelines. For temperature & humidity mapping for warehouses and loading bays to assist with regulatory compliance according to GDP and GMP standards. Temperature mapping of trailers, cold rooms, temperature controlled storage areas and food storage and processing areas complies with BRC and GMP standards.

Situations that require temperature mapping


New Equipment

Mapping qualifies new critical equipment upon installation. Governing bodies for many industries require all new temperature storage areas to be mapped.

Serviced Equipment

After a storage unit is serviced, it is best practice to conduct a mapping study to requalify the unit and ensure optimal performance.

Relocated Equipment

Many temperature-controlled units like fridges and freezers are often moved around a premises. Performance can be significantly impacted so temperature mapping is a preventative measure.

Periodic Testing

Continuous remapping is recommended annually for most storage enclosures, although the temperature mapping study frequency will often be determined by the type of storage unit.

Seasonal Conditions

For larger storage areas such as warehouses, the environmental conditions can be affected by seasonal changes. It is therefore advisable to test these areas on a consistent basis. In winter, heating systems will be required to perform and in summer, cooling systems need to be tested during the peaks of environmental temperatures to ensure adequate storage temperature levels are maintained.

New Storage Item

If a different product is stored or sterilised, then the characteristics/ performance of the storage unit can change and testing is required to prove that the equipment can perform to specification to the new product.
