Because this logger sits outside, its battery life is much longer than the TRIL-8 model that sits in the super-cold environment.
See the temperature at a glance without having to open the freezer or shipping package.
The LogTag is so simple to set up and use that you'll be an expert in no time. We have a full LogTag training program on our site
Our TRIL probe-less Dry Ice LogTags are great for their convenience, but this probe model has its own advantages.
First, the battery will last longer than the TRIL model.
Importantly, you can see the temperature inside the super-cold environment, and see immediately if there is a problem.
Note that this logger has a fixed battery that cannot be replaced. We recommend hibernating the logger when it is not in use.

If you need some form of certification about the accuracy of your logger, you have various options.
This is a free certificate that comes with every LogTag. You can access this certificate through the configuration page in LogTag Analyser.
This paid certificate is from a laboratory that uses testing instruments that have been calibrated using NATA-traceable instruments.
This paid certificate is from a laboratory that has full NATA certification.
Before you can start using a new logger, you will need to configure it with all the settings appropriate to what you are logging.
This is not difficult, and we have instructions on how to do it on this website, but if you would prefer us to do it for you, that service is available at a small cost.
We can pre-configure your LogTag with our recommended settings for:
This means, all you will need to do when you receive your LogTag, is press the Start button and place it in the environment to be monitored.
Latency, when it comes to temperature logging, refers to the delay between a change in temperature and when that change is detected and recorded by the logger. This delay can be due to the sensor’s design, the materials it’s placed in, or the logging interval. While it might sound like a disadvantage, latency can actually serve a useful purpose in certain environments—particularly where short-term temperature spikes are common but not harmful.
For example, in a busy commercial fridge, the temperature may briefly rise every time the door is opened. A logger with high latency won’t immediately react to these short fluctuations, helping to avoid unnecessary alarms or false data indicating a problem when there isn’t one. In these cases, a slight delay in response acts like a filter, focusing attention on real issues—such as prolonged exposure to unsafe temperatures—while ignoring the everyday ups and downs that don’t affect product quality or safety.
Depending on the type of logger you have, connecting your logger to your PC means either:
First Generation LogTags use a separate Reader (sometimes called a dock) for configuration and for downloading recorded data.
The Second Generation loggers only require a USB port or cable. Apart from saving the cost of the Reader, this makes them much better suited for shipping, because the recipient doesn’t need a LogTag Reader to download a report about the shipment’s journey.
