TMS 2000, TMS 3000 with ES820-100 Non-Discriminating Liquid Sensor, ES820-200 Discriminating Liquid Sensor

INTERSTITIAL DETECTOR (LIQUID-PHASE)

Detector:

Output type	qualitative
Sampling frequency	continuous
Operating principle	optical sensor

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.

Model ES820-200: 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.
