Summary: Inlet not running, water samples, calibrated 7700

West Pond
2014-09-10

I arrived with Sara about 12:30. It was clear and hot with almost no wind. The inlet was not running and the water level was a little low with the CO2 probe almost out of the water.

Sara took water samples.

I replaced the mounting bracket on the 7550 box and installed the temperature sensor.

We calibrated the 7700. The zero was not bad at 25ppb, the span was a little off at 80ppb.

The 7700 read: 2.1ppm, 62RSSI, 82 after cleaning and before cal.
No change in reading after cal.
