www.ctemps.org offers instructional videos to train instrument users on how to assemble field deployable fiber-optic distributed temperature sensing systems (FD-DTS). This video gives a brief introduction to the calibration bath set-up, shows a flange-structure for a cable coil inside a cooler, and a bubbler for keeping the bath well mixed. We also show you how to power the bubbler with a small solar panel (mounted on the back of the DTS enclosure) and battery.
