All companies will have different requirements, but these are our standard recommendations for industries.

What is an iButton Thermochron?

What is an iButton Thermochron?

Our Thermochrons use the popular iButton technology – a strong, versatile, self-contained electronics platform.

No External Probe Needed

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 test environment – just place the Thermochron directly where you want the temperature monitored. There are even cases that allow Thermochrons to be used underwater.

Reading Data

At regular intervals, simply retrieve the Thermochron and place it in the special iButton 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.
