Rec No.	Date	Loc From	Title	Loc To	Notes
7234	2025-05-16	Lab none	Tested	Lab none	This sensor had good numbers today. Not sure what to do with it.
7199	2025-04-24	Lab none	Tested	Lab none	I tested this sensor in the lab. The serial interface and temperature seem fine but the CH4 is reading -10.00. I downloaded all the data and erased the internal data file. I will try to get advice from Pro-Oceanus.
7198	2025-04-17	Gilbert Tract CH4 Probe Tower	Removed	Lab none	Removed from float at GT boardwalk after animals chewed its cable, it also started to read -10.00 % CH4.
7107	2025-01-15	Lab none	Installed	Gilbert Tract none	Installed on a floating frame with an external battery pack on top so that the CH4 probe is horizontal just below the surface and the battery pack is horizontal just above the water. It's connected to the boardwalk with a yellow plastic chain. Should be collecting an average of 5 readings every 15 minutes.
