Push Button Start
Configure the Tag to use Push Button Start and there is no rush about getting the Tag from the Reader to the refrigerator. Logging will not begin until the Start button is pushed.
Visual Alerts
If the Tag logs temperatures outside the safe range you have set, the Alert LED will flash red, giving you a handy visual notification that there has been a problem.
Easy to use
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
Why use an external probe?
LogTags are tough and versatile, bu there are some places they just can’t go.
In particular, when logging the temperature of liquids, you will need a probe. An example might be measuring the cooling rate of a large batch of custard.
Probes are also useful to monitor temperatures inside coolers and other containers without removing the lid.
Another use might be measuring soil temperatures. The probe is driven into the soil while the LogTag remains clean and protected above ground.

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.
