| Conductivity Sensor | |||||
| 2016-11-16 | 11020258 | U24-002-C | Installed | Conductivity Sensor B | The HOBO conductivity sensor was put in the water near the existing conductivity sensor at the southeast corner of the scaffolding for an intercomparison with the Campbell CS547A sensor b/c we're technically out of the CS547A range. It is tied to the tower with some rope. |
| 2017-05-25 | 11020258 | U24-002-C | Removed | Conductivity Sensor B | Removed from Mayberry for use on the temporary tower at East End |
| 2011-01-28 | 5688 | CS547A | Installed | Conductivity Sensor | Installed at Mayberry. |
| 2011-11-08 | 5688 | CS547A | Removed | Conductivity Sensor A | We pulled the conductivity sensor from the main tower to clean and test in the lab. Then we will reinstall it at the Tule tower. |
| 2011-11-22 | 5688 | CS547A | Installed | Conductivity Sensor A | Installed on the Tule Tower scaffolding but the data logger program is having trouble so no readings yet. |
| 2013-10-16 | 5688 | CS547A | Removed | Conductivity Sensor | Removed from Mayberry since readings were bad. |
| 2014-06-13 | 5688 | CS547A | Installed | Conductivity Sensor A | Installed at about 10cm below the water surface at Mayberry with CR10x, home-made interface sn 547-01 and 5 level TC profile. |
| 2016-04-28 | 5688 | CS547A | Installed | Conductivity Sensor | Installed new conductivity sensor. The old one was removed last time since it was reading weird numbers. |
| 2020-05-26 | 5688 | CS547A | Calibration | Conductivity Sensor A | Cleaned and calibrated in the field with DI water (0 mS) and a YSI solution (10,000 uS). Need to double check units -- are these the temperature-corrected mScm readings from the datalogger, where the temperature correction occurs in the datalogger program? In DI water: 0.54 (units?) In 10,000 uS calibration soln: 10.15 If unit is mScm, Calibration: (Corrected mScm) = 1.04 * (Sensor mScm) - 0.562 |
| 2020-12-09 | 5688 | CS547A | Removed | Conductivity Sensor A | Removed from MB and brought back to the lab for testing. Temperature reading is too high. |
| 2013-12-06 | 6097 | CS547A | Installed | Conductivity Sensor A | installed conductivity probe at Mayberry tule tower scaffold crossbar, about 50 cm below water surface. |
| 2016-04-13 | 6097 | CS547A | Removed | Conductivity Sensor | Removed from Mayberry tower together with interface module since it was giving bad readings. |
| 2020-11-03 | 7157 | CS547A | Moved | none | Moved from SW to MB for a temporary intercomparison because there was no water at the SW tower and sn 5688 at MB was giving high temp number |
| 2020-11-19 | 7157 | CS547A | Removed | Removed sensor and factory A547 interface from MB after concluding the conductivity sensor comparison. Brought back to the lab to test a homemade A547 board. | |
| 2020-12-09 | 7157 | CS547A | Installed | Conductivity Sensor A | Installed at MB with interface sn 547-02 to replace sn 5688, which was brought back to the lab for testing. |
