how thermochrons work

Unlike other temperature loggers on the market, you do not need an external probe with Thermochrons – the button-sized loggers are tough enough to handle just about any environment. This means you do not have to drill holes in your refrigerator or cold storage, just place the Thermochron directly where you want the temperature monitored. There are even cases that allow Thermochrons to be used underwater.

At regular intervals, simply retrieve the Thermochron and place it in the special data reader. The eTemperature software supplied with the reader downloads the temperature data from the Thermochron and presents it as both a spreadsheet of the logged times and temperatures, and a graph. The graph makes it easy to spot abnormal temperature spikes.
