#Overview
The EX-LC-S22 is a compact spot leak detector for detecting water, gasoline, diesel and acid-base liquids with a concentration of less than 30% after dilution at a fixed monitoring point. It uses photoelectric detection technology and a sealed structure to improve stability in demanding environments.
When leakage occurs, the detector outputs a relay signal that can trigger an alarm, close a valve, or send a signal to an external monitoring module.
#Key Features
