| Rec No. | Date | Loc From | Title | Loc To | Notes |
|---|---|---|---|---|---|
| 6692 | 2024-04-30 | Lab none | Repair | Lab none | I spliced this cable back together where the cow chewed it. The end has a completion resister for the thermistor half bridge. A quick test in the lab window shows it matches the other IRT within 0.5C - as good as you get without a fancier setup. |
| 6683 | 2024-04-22 | Tonzi Infrared Temperature Tree Crown | Removed | Lab none | Removed from the IRT tripod because cows had chewed the wires off. |
| 1806 | 2015-05-06 | Lab none | Installed | Tonzi Infrared Temperature Tree Crown | Installed at Tonzi to the east just north of the road. This sensor is point down on top of a small tree. |
