Removed |
Lab none |
Removed with the temporary tower set up near the building at the rice project for the LGR COS experiment. This box had a significant amount of water inside. There was some corrosion on the power connectors but it looks like it was running up until I turned it off. I blew out all the connectors and stuffed it full of desiccant in the lab. |
