How it Works
Unlike some ozonesondes, ECC sondes do not require an external electrical potential. The ECC gets its driving electromotive force from the difference in the concentration of the potassium iodide solutions in the instrument’s cathode and anode chambers. When ozone enters the sensor, iodine is formed in the cathode half cell. The cell then converts the iodine to iodide, a process during which electrons flow in the cell’s external circuit. By measuring the electron flow (i.e., the cell current) and the rate at which ozone enters the cell per unit time, ozone concentrations can be calculated.
Connect To Popular Radiosondes
The ECC Osondesonde is built to connect with a variety of radiosondes in order to track live data during flight with a data acquisition system.
Photo displays i-Met4 attached to biodegradable flight box.
