iButton Data Loggers
iButton® data loggers track the temperature or temperature and humidity of specific assets or locations. Now you can easily log the thermal exposure of an asset during shipment to see if it stays within specified temperature ranges. iButton data loggers make it simple and inexpensive to monitor anything that is temperature sensitive, including pharmaceuticals (vaccines, drugs, reagents), fresh or frozen foods (fruits, vegetables, dairy/dessert products), biological items (animals, blood products, soil), or heating/refrigeration/freezer systems. And like all iButton devices, the stainless steel casings makes them rugged, reusable, and portable. They are so small that they fit anywhere and can deliver years of reliable, highly accurate temperature or temperature and humidity readings.
