Temperature mapping
Remote temperature mapping by equipment, with every price posted
We ship calibrated wireless sensors for your fridge, cold room, warehouse or vehicle, and your team places them with us on a video call. The readings reach us live, and the signed report comes 2 business days after the study.

US dollars, before tax, for a remote study. Shipping at the carrier's rate, no markup. On-site service and -80°C (-112°F) freezers are quoted separately.
Keep some of the sensors after the study, and you have continuous monitoring for $250 a sensor a year.

By equipment
How each space is mapped
Fridges and freezers: 4 to 19 sensors over 3 days
Sensors go in the corners, the center, by the door and near the fan, with one outside the unit. Three days catches the compressor and defrost cycles. The protocol says whether the unit is mapped empty, full or both, because a loaded unit behaves differently.
Cold rooms: a grid at two heights
The grid grows with the room, and the study adds a door-open test and a power-off test, which show how long the room holds. WHO guidance runs a cold room study for 24 to 72 hours.
Warehouses: 7 days, three heights, summer and winter
Sensors go every 5 to 10 m (16 to 33 ft), low, middle and high, because heat gathers under the roof and at the docks. The study includes a weekend.
Vehicles: real routes, once in each season
Sensors go from the front wall to the doors, floor to ceiling, and the vehicle runs its normal stops, in summer and in winter.
Ultra-low freezers are quoted separately
Freezers at -80°C (-112°F) need sensors rated far colder, so we quote them. A larger space takes more sensors, and is priced the same way, by sensors and days.
Every map ends with where the monitoring should go
Mapping guidance uses the map to decide where the permanent sensors go: at the warmest and coldest spots it finds. Every report names those spots.
The rules
Which rules ask for a map
USP, United States
USP's chapter 1079.4 sets out how to map a drug storage area, for every link that stores or moves a finished drug.
About the chapterWHO
Maps a space before first use, after a significant change and on a cycle such as every 3 years, and warehouses and vehicles in both seasons.
WHO Supplement 8Health Canada
GUI-0069 makes mapping a rule for drug licence holders, the 3PLs they contract and their vehicles.
GUI-0069Common questions
What is temperature mapping?
A study that places many calibrated sensors through a fridge, freezer, cold room, warehouse or vehicle for a set time, to find where it runs warm or cold and how fast it recovers. The result shows where product is safe and where the permanent monitoring sensors should go.
How much does temperature mapping cost?
Our posted prices, in US dollars, for a remote study: $350 for a compact fridge or freezer, $850 for a single-door upright, $1,600 for a double-door unit or a small cold room, $1,400 to $1,850 for a vehicle in both seasons, and $4,750 to $7,900 per season for a 10,000 sq ft warehouse. Shipping is billed at the carrier's rate, with no markup.
Can temperature mapping be done remotely?
Yes, and it is our default across the US and Canada. We agree the protocol on a call, ship calibrated sensors with a placement map, and check each spot on a video call while your team places them. The readings reach us live, and the signed report comes 2 business days after the study ends.
Do you offer on-site temperature mapping?
Yes. Assisted installation and full white-glove service, where a technician places and collects the sensors and runs the tests, are quoted by location. In Ontario and Quebec, travel and installation are free.
Does the kit need our network or IT team?
No. The gateway sends the readings over its own cellular link, so nothing joins your network and there is nothing for IT to set up.
How long does a temperature mapping study take?
Three days for a fridge, freezer or small cold room, two days in each season for a vehicle, and seven days for a warehouse. The signed report comes 2 business days after the study ends.
What is the difference between temperature mapping and temperature monitoring?
Mapping measures many points for days, to learn how a space behaves. Monitoring watches a few points for years, to catch a problem when it happens. The map tells you where the monitoring sensors belong.
How often should temperature mapping be done?
WHO guidance maps a space before it is first used, after any significant change such as new racking, new equipment or a new layout, and on a cycle such as every 3 years. Warehouses and vehicles are mapped in summer and in winter where the seasons matter.
What does a temperature mapping report include?
The lowest, highest and average reading at every sensor, the mean kinetic temperature, the warm and cold spots, recovery times after the door and power tests, any reading outside the range, the calibration certificates, the raw data, and where the permanent sensors should go. A certified Renergy engineer reviews and signs it.
