Our Process

Temperature mapping is the process of installing data-logging sensors throughout a room or unit—from fridge-freezers to entire warehouses—to monitor and analyze temperature data. 

By strategically placing these sensors in predetermined locations, we can identify hot and cold spots. Products can become unusable, even dangerous, if kept in improper conditions.

PV can complement your in-house team or guide the project from start to finish. Our team is known for offering competitive and cost-effective temperature mapping solutions while ensuring our client’s system is accurate within defined limits. 

Our Approach

The PV team has the flexibility and experience to offer varying levels of support, depending on your resources and capabilities. 



Performance Validation’s equipment is maintained in a calibrated and validated state. We have Vaisala wireless data loggers and Kaye wired systems for temperature and humidity mapping. Our equipment inventory also includes self-contained biological indicators and an incubator for verification of sterility processes. Our internal procedures have been developed to govern the use of equipment to ensure a consistent approach to equipment set-up and data retrieval.
