Temperature Mapping Services

How temperature mapping works

An array of calibrated, NIST-traceable data loggers is placed in a strategic 3D grid, at low, medium and high elevations, throughout the facility. The sensors record temperature continuously for 24 to 72 hours, or up to 7 days in large warehouses, capturing door openings, defrost cycles, HVAC performance, product loading and seasonal variation.

Why map your facility

Mapping gives you a three-dimensional temperature profile of your storage space and shows auditors, with documented evidence, that the whole facility holds safe conditions.

• Find hot and cold spots near doors, vents and walls, where temperature excursions are most likely.
• Reveal thermal stratification and dead zones where temperature may drift outside safe limits.
• Decide exactly where permanent continuous-monitoring sensors belong, with data to justify each location.
• Support your own quality procedures for storing pharmaceuticals and perishables, whether you work to GMP, WHO guidance or Health Canada guidelines.

Who needs temperature mapping

Mapping applies wherever product quality depends on a controlled space.

• Pharmaceuticals and vaccines: document that cold storage holds the conditions needed for drug stability and vaccine potency.
• Food and beverage: check that walk-in coolers, freezers and production areas hold the temperatures set in your HACCP plan.
• Laboratories and cleanrooms: document environmental uniformity for GLP/GMP programs and equipment qualification.

The mapping process

Your team places the kit's dataloggers (probe, wireless no-probe or NFC) in a 3D grid throughout your walk-in cooler, warehouse or freezer, and the readings collect in LF Cloud over the study period.

• Follow your own quality team's mapping protocol (IQ/OQ/PQ stays with you).
• Place loggers at high, medium and low elevations.
• Simulate normal operational use, including door openings and closings.
• Identify thermal stratification and dead zones.

How the DIY mapping kit works

LoggerFlex ships a set of dataloggers in a 9- or 15-point layout; you place them and run the study, LF Cloud produces the Temperature Mapping report (PDF or Excel), and you send the sensors back when finished. Placement guidance, cloud access to your data during the study and technical support throughout the process are included.

Frequently asked questions

What is temperature mapping and when do I need it?

Temperature mapping is a structured study that documents how temperature and humidity vary across a controlled space such as a warehouse, cold room, fridge, or stability chamber. It is typically required for GxP, GDP, and cold-chain qualification to prove the space holds product within specification.

Does LoggerFlex provide the sensors and the study?

LoggerFlex ships the sensors as a DIY kit (a 9- or 15-point layout; probe, wireless no-probe or NFC). You run the study and send the sensors back, and LF Cloud produces the Temperature Mapping report. The study protocol and the qualification decision stay with your quality team.

Why use NIST-traceable calibration for mapping?

Mapping is only defensible if the measurements are traceable to a recognized standard. LoggerFlex sensors carry NIST-traceable calibration certificates, so the study results stand up to FDA, GDP, and quality-system scrutiny.

Can the same sensors stay in place for ongoing monitoring afterward?

Yes. After the mapping study you can leave LoggerFlex sensors installed for continuous monitoring at the identified hot and cold spots, so qualification flows directly into day-to-day compliance monitoring in LF Cloud.
