Test Results
California requires annual certification of all leak detection equipment. The certification of discriminating sensors should include functional testing of both water and product detection capabilities.

Specificity Results
Manufacturer claims sensors will respond to any liquid after sensor's threshold is exceeded.
Manufacturer's Specifications
All sensors are designed to connect to a controller system that indicates the status of the sensor. Manufacturer indicates that discriminating sensors ES 825-400F and 400XF incorporate an optical liquid sensor and a conductivity sensor. The sensors discriminate between product and water by determining if the optical sensor, which responds to any liquid, or the conductivity sensor, which responds only to water, causes an alarm.
Comments
"F", "XF", and "CF" are variations of the same sensor distinguished by the material they are made of, such as PVC and Teflon.
