Corona Sensor Refrigerant Leak Detector
Elitech corona leak detectors feature sensitivity adjustable, auto reset, quick response, audible and visual alarms, etc, making them very economical and easy to use.
Corona sensor is the most widely used sensor in refrigerant leak detectors. In the vicinity of the tip electrode with a large radius of curvature, the local electric field intensity exceeds the ionization field intensity of the gas, which causes the gas to ionize and excite, and thus corona discharge occurs. When corona occurs, light can be seen around the electrodes and there is a sizzle. Corona leak detectors are based on this principle.
