DS1921K Thermochron iButton Kit Overview
The DS1921K Thermochron® iButton® Kit introduces users to the temperature logging capabilities of the Thermochron. Using a personal computer, the Thermochron temperature logger can be setup for a temperature gathering mission. After a temperature gathering mission, the data can be downloaded and viewed or exported. Instructions and software are available to download for free from this website.
The starter kit includes one of each of the parts listed below. The DS1921K is also capable of evaluating any sensor iButton, including high-capacity thermochrons (DS1922L and DS1922T), the hygrochron (DS1923), and the temperature-only iButton (DS1920). Please note that only the DS1921 is included in the kit. Other sensor iButtons will need to be purchased separately.
