5239 2021-04-15 Lab none Installed Bouldin Alfalfa RH & Temp Installed on the BA tower after reconnecting sensor to cable screw terminals in the lab. The collar has a metal set screw.
5235 2021-04-13 Lab none Repair Lab none Reconnected loose wires on cable to connector. The connector has tiny screw terminals, so it was pretty convenient; no soldering needed. Ran for 10 minutes in the lab and values were reasonable.
5232 2021-03-30 Bouldin Alfalfa RH & Temp Removed Lab none Removed from BA and brought back to the lab for repair. This sensor had fallen to the ground. The cable head needs rewiring.
