The Gems™ LS-10 liquid sensor accurately detects the presence of liquid in fiberglass double-wall tanks, containment sumps and double-wall pipes. Dry contact switching ensures dependability throughout its long service life. This reusable leak detection sensor easily fits small, interstitial spaces and senses liquid hydrocarbons or water. The LS-10 Series Single-Point Leak Detection Sensor unit is unaffected by hydrocarbon vapor, thereby reducing the risk of false alarms. The LS-10 sensor’s rounded design makes it easy to remove, clean and reinstall after an alarm condition is triggered, or for maintenance.
