Data SheetThe Excelog One is a miniature, single-channel, dual-function thermocouple data logger and simulator.
Measure, log and calibrate thermocouple equipment with one compact device.
The colour display, built-in controls and intuitive menu system allow for quick configuration of the Excelog One’s settings. On-board memory and an included USB cable make it straightforward to download the logged data with our free software.
