LogTag Temperature Data Loggers are the ideal solution for continually monitoring the temperature where ever and when ever temperature is critical. They automatically record the date, time and temperature at a set interval. You can then download the results to a PC where they can be viewed, analysed and saved for later.


Additional information – Logtag-Dry-Ice-Brochure

Probe-less temperature recording from +40°C to as low as -80°C, great for use in transit monitoring of articles stored in packaging incorporating dry ice cooling.

The Logtag has LCDs that lets you see at a glance that the system is working and if there has been a problem. At the press of a button, it allows you to mark significant events during its recording cycle. Now Multiuse, up to 1000 hours at -80°C.
