This LogTag has enough memory for 15,900 recordings - that's 55 days at 5 minute intervals.
If the Tag logs temperatures outside the safe range you have set, you will be alerted by an audible alarm. You can check the status of the logger on screen.
This model features a replaceable battery. The battery is a regular watch battery, readily available for leading retailers.

Attaching this LogTag to a vial filled with glycol (antifreeze), gives you the most accurate measurement of actual liquid temperatures. See any temperature events at a glance and get an audible alarm if temperatures are out of range.
Â
Place the probe inside your cool transport container running out to your LogTag, and you will have an accurate display of the temperature inside without opening the lid. An audible alert will sound if the internal temperature breaches limits.
If you have a Medisafe refrigerator and would prefer to have a logger with temperature display, this model is a completely compatible replacement for the TREX-8.

To use this LogTag, you will need a USB interface and the LogTag Analyzer software installed on your PC.
This LogTag uses the same Reader as other LogTags, so if you already have one, it will work with these models.
If not, make sure you order one as well. As a bonus, we include the latest free LogTag Analyzer software on USB.

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.Â
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.
