Abstract:
1. A leak detector for detecting leakage of an electrolyte solution comprising: a device housing, the device housing comprising bottom surfaces; at least one light source in the device housing, the at least one light source emitting light that at least partially reflects from the bottom surfaces of the device housing, and is at least partially refracted by the bottom surfaces and fluid in contact with at least a portion of the bottom surface that the light is incident upon; and at least one light detector in the device housing, the light detector receiving the partially reflected light to obtain a measured light intensity; and control electronics coupled to the leak detector; wherein the control electronics determine type of fluid in contact with at least a portion of the bottom surfaces of the leak detector based on the difference between the measured light intensity and the intensity of light produced by the light source so that leakage of the electrolyte solution is detected.
