This model has two temperature sensors – an internal sensor and external probe.
When placed in a vial of glycol (or a similar non-freezable liquid), the probe accurately mimics vaccine temperatures.
Requires Gateway to connect to the internet.
Remember, there are NO ongoing fees with Clever Logger.

Traditional loggers have to be manually downloaded to get their data.
Clever Logger changes that. The loggers broadcast their temperatures and the gateway picks them up and saves them to the internet every few minutes.
This gives you a “live” log of temperatures available on any internet device (computer, tablet, phone), anywhere in the world on the Clever Logger web site.
The website also gives you immediate alerts about problems and automatic reports to your email inbox.
Latency is the time it takes for something to change temperature, and different substances have vastly different latencies. If you apply a heat source to air, the air quickly becomes hot. If you apply a heat source to a liquid, it will heat up, but much more slowly.
So, if your logger is measuring air temperature, you will see rapid fluctuations in temperatures. Whereas, if your logger is measuring a liquid, those fluctuations will be much less pronounced.
In the graph below, we can see the Dual Sensor logger in action. The blue line represents air temperature, measured by the loggers internal sensor, while the pink line represents the temperature of the glycol in the vial, measured by the external probe.
You can see that the variation between minimum and maximum temperatures is much lower for the liquid temperature than for the air temperature.
This logger is specifically recommended for vaccine fridges
The Clever Logger logger has two jobs:
If we configure the Dual Sensor logger so that the alarms are triggered by the air temperature sensor, we will be notified immediately if the temperature goes outside our set limits.
However, since we are interested in the temperatures of the liquid vaccines, it is perfectly acceptable to log the temperature of the glycol liquid in the vial.
If the temperature starts to rise, we will find out about it from the air temperature sensor well before the liquid-immersed sensor reaches 8°, and hopefully in time to remedy the problem before the log shows a breach.
Note that only the metal tip of the probe is submersible. If liquid enters the join between the cable and the probe tip, the probe can be damaged.
