iButtons

iButtons are computer chips encased in durable stainless steel cans. Because they are both small and rugged, they are ideal for applications where information needs to travel with a person or object. iButton varieties include Address Only, Memory, Real Time Clock, and Temperature & Data Loggers.

For information regarding Temperature and Humidity Data Loggers, please visit our Thermochron Page.
