Abstract |
The Orion Calcium Ion Electrode No. 93-20 was evaluated for suitability as a calcium ion sensor for monitoring or in-situ marine applications by testing for the following parameters: accuracy, precision, temperature dependence, short- and long-term stability, durability, sensitivity to fluctuations in light intensity and flow conditions, response time as a function of temperature and concentration, and variability between modules. The tests were performed at 10 degrees C and 25 degrees C in freshwater, synthetic seawater, and natural waters (35-, 20- and 5ppt salinity). A description of the sensor, theory of operation, and a summary of the test results are included. |
