Cold Chain

Celsor™ delivers wireless monitoring and reporting of ambient air and controlled environment temperature and humidity, with "if this then that" functions and alerts to anomalies or undesired states.

Ideal for monitoring and alerts from cool stores, fridges and freezers in food storage, mobile facilities, refrigerated transport, supermarkets, medical clinics, museums, science and research labs.

More than temperature monitoring

Celsor™ solves temperature management problems often faced in produce storage, food processing, storage and refrigerated delivery. The wireless Celsor units enable managers to monitor the temperature and humidity of chilled products or any controlled environment, in fixed locations or on the go, and to receive alerts if the temperature rises or falls too far, for too long. Any number of people can be on the roster for alerts to their phone.

Monitoring Simplified

No wiring! Place the Celsor temperature and humidity units anywhere at all. The base unit has fixed temperature sensor, or sensor can have 1m/3m flying leads. Celsor communicates from inside chillers, fridges, freezers, and refrigerated transport. Simply hang on a hook or attach to surfaces with screws or ties. They last for about 10 years on a battery, warning you when they need recharging. If calibration is needed annually, they may be swapped with newly calibrated units.

Customers who have installed Celsor™ in their cool stores and food preparation facilities see immediate benefits including:

No wiring, no fuss
Easy self-installation in moments, with the ability to place sensors anywhere, with no restrictions from any wiring. No cellular, no Wi-Fi needed for the Celsor devices. No third party required for any part of the service.

Prevents contamination between zones
No need to physically visit or disturb the location where the monitoring is taking place to obtain data.

Removes human error and saves time
Reliable and accurate temperature data that shows history and trends. No reliance on people to notice problems with this perfect 24/7 supervisor on the job. Goodbye clipboard!

Improved machinery care and maintenance

Graphs provide visibility into chiller performance and enable preventative maintenance. Machinery problems are discovered automatically when conditions do not fit normal machinery operation patterns.

Automated actions and control

If-This-Then-That functions to enable/disable machinery or controls upon specific conditions.

No specialist displays

The display is in your pocket, on your phone App. A management dashboard is available on a browser too. Insert your own site layout map to view temperatures/humidity where there are multiple measurement points.

Alerts when action needed
Immediate knowledge of a problem allows a fast response. Alerts are configurable, with two high-temperature levels and two low-temperature levels allowing consistent and accurate temperature maintenance. Set up your own alerts roster.

Easy data audits and compliance
Temperature measurements are permanently and securely available online, accessed with username/password. Quick access to proof of compliance throughout a selected period or during a delivery.

Add extra sensing points with ease
No specialists needed, simply add in a Celsor unit wherever you want a new sensing point. If you are expanding or need more measurement points, now is the time to upgrade to a modern wireless system.
