iButtons

iButtonThe Thermochron family of iButtons are temperature data loggers which record and store time, temperature, and optional humidity for later analysis. The iButton's embedded computer chip integrates a globally unique address, a thermometer, a thermal history log, an alarm event log, and additional memory to store user data, such as location data or a shipping manifest. Thermochrons are recyclable, and under normal conditions, will log data for up to 10 years or 1 million temperature measurements. The following table is a comparison of the available Thermochron models:

Scientific Research Projects - iButtons can be discretely located in the environment for monitoring the temperature of ecosystems. Their low-cost makes it possible to have multiple loggers spread throughout an area, and their small size means they can be attached to places previously impossible.

Monitoring Thermally Sensitive Products - iButtons easily attach to containers of frozen or fresh foods, blood products, and chemicals or drug reagents, recording time and temperature during transport and storage. By logging the thermal experience of temperature-sensitive material, you can pinpoint responsibility for spoilage and take corrective action.
