Temperature history is recorded by the IQT 4020 K Thermocouple. With a reusable K thermocouple, the module can store over eight thousand temperature readings.
Intervals between readings, which can be set by the user, can vary from one minute to twenty-four hours. To analyze the readings the user can upload the data to a PC.
The economical IQT™ Software (IQT 4050) allows simple uploading of the data to a Windows environment personal computer via the serial port. The data can then be imported into any spread sheet or word processor. Also, the temperature history can be graphically displayed with respect to time.
