Huge Memory

This LogTag has enough memory for 15,900 recordings - that's 55 days at 5 minute intervals.

Audible Alarm

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.

Replaceable Battery

This model features a replaceable battery. The battery is a regular watch battery, readily available for leading retailers.

The ultimate vaccine monitoring solution

How warm did your vaccine stock get? See at a glance.

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.


LogTag with glycol

Ideal for transport logging

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.

LogTag on Cooler

The ideal replacement for Quirks Medisafe loggers

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.

Do you have the USB Reader Interface?

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.
