2707 2017-04-04 Twitchell Rice DO Sensor Removed Lab none Removed with Twitchell Rice tower decommissioning.
2394 2016-08-12 Lab none Installed Twitchell Rice DO Sensor Reinstalled at the Rice tower after being removed for spring draw down and calibration in the lab.
Reconnected the sensor to port 9, reading 27mV when connected and immersed in water in well. DO sensor was ziptied about 6-8 inches from the top of the well.
2390 2016-08-11 Lab none Serviced Lab none Scrubbed with vinegar to remove residue and replaced small o-ring and membrane.
The new calibration is:
M = 8.73/17.8 in (mg/L)/mV (aka ppm/mV) (@ 22C).
2238 2016-04-13 Twitchell Rice DO Sensor Removed Lab none Removed with tower from field for planting. Needs to be serviced in the lab and reinstalled when the field is flooded.
2114 2015-11-25 Lab none Installed Twitchell Rice DO Sensor Reinstalled at the Rice tower after being removed for fall draw down.
2102 2015-11-23 Lab none Serviced Lab none Serviced probe to go back in the field this week. The new calibration is:
M = 9.45/36.1 in (mg/L)/mV (aka ppm/mV) (@ 18C).
1857 2015-05-19 Lab none Calibration Lab none Serviced probe to go back in the field this week. The new calibration is:
M = 9.45/39.8 in (mg/L)/mV (aka ppm/mV) (@ 18C).
1743 2015-03-05 Twitchell Rice DO Sensor Removed Lab none Removed from Twitchell Rice because the field is dry and we moved the tower for plowing
1628 2014-11-11 Lab none Installed Twitchell Rice DO Sensor Re-installed at the rice.
1627 2014-11-06 Lab none Serviced Lab none Serviced probe to back back in the field next week. The new calibration is:
M = 8.24/28.61 in (mg/L)/mV (aka ppm/mV) (@ 25C).
1558 2014-09-10 Twitchell Rice DO Sensor Removed Lab none Removed from the Twitchell rice because the field in drained.
1346 2014-06-12 Lab none Installed Twitchell Rice DO Sensor Installed at the rice. DO-08 was calibrated in the field: M = 8.24/38.61 in (mg/L)/mV (aka ppm/mV) (@ 23C). The probe is 3 cm above the soil surface.
