*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.
ES820-100 Non-Discriminating Liquid Sensor
| Unleaded Gasoline | Diesel | Water | |
|---|---|---|---|
| Detection time (sec) | <1 | <1 | <1 |
| Fall time (sec) | <1 | <1 | <1 |
| Lower detection limit (in) | 0.35 | 0.34 | 0.35 |
ES820-200 Discriminating Liquid Sensor: This sensor can only respond to liquid directly in contact with the detection element, and is unable to detect a product release floating on an existing pool of water whose height exceeds the level of the detection element.
| Unleaded Gasoline | Diesel | Water | |
