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-Temperature-Humidity-Logger

The Logtag Temperature & Humidity Logger is designed for a temperature range of -40oC to 85oC and humidity range from 0% to 100% relative humidity. 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, such as the door being left open, or a new delivery.
