5429 2021-08-26 Lab none Notes Lab none Partly cleaned this sensor and tried to take the cable off. However, the connector at the top of the sensor twists loose from the body of the sensor so I don't think it's worth keeping. I'm not sure if the connector was already loose, or if I loosened it trying to table the cable off.
5237 2021-04-13 Lab none Tested Lab none Tested in the lab and the CO2 signal responded to my breath. I'll keep it running for a while and see if the noise comes back; maybe it just needs a new connector/cable. This sensor needs a scrubbing.
5208 2021-03-16 Mayberry CO2 Probe A Removed Lab none Removed from MB b/c it was sporadically reading noise. it was replaced by sn GP20150111.
4410 2017-05-25 Mayberry CO2 Probe A Moved Mayberry CO2 Probe A Moved to floating boom. Depth is ~-15cm below water level. Co-located with sn GP20150111 (which was removed 2017-08-16).
4409 2017-05-10 Mayberry CO2 Probe A Moved Mayberry CO2 Probe A Adjusted depth? on fixed boom. Depth is -10cm based on water level on 2017-05-10. All three eosCO2 sensors (sn GP20160070, sn GP20160069, sn GP20150111) are at -10cm depth because of low water level.
2638 2017-02-23 Lab none Installed Mayberry CO2 Probe A Installed on the new water sensor boom in the top location - currently 8cm below the water surface
