This video demonstrates an industrial CHP leak detection test using an organic solvent leak sensor designed for fast and selective liquid leak detection in chemical and semiconductor environments. The YHSP-SA leak detection sensor shows no reaction to water, while triggering a rapid alarm when exposed to CHP, proving reliable performance for hazardous liquid leak monitoring.
Test Substance: CHP (organic chemical substance) supplied by Dong Sung Chemical
Core Device: Electronic leak point sensor for organic solvents (Model: YHSP-SA)
Test Objectives:
To verify the sensor’s selective detection capability, ensuring that it does not react to water (H₂O) or other non-target liquids
To measure the alarm response time when exposed to the target chemical substance, CHP

The video verifies the performance of the industrial leak detection sensor through two clear test stages, demonstrating both false alarm resistance and rapid chemical response.
First, the leak detection sensor is immersed in water to confirm its selective response characteristics. The operator keeps the sensor in water for 20 seconds and checks whether any alarm is triggered.
Result: No response. Even after 20 seconds, the sensor output does not reach the preset alarm threshold of 2.0483, and no alarm is activated. This result shows that the sensor is highly stable and helps prevent false alarms caused by water, rain, condensation, or similar non-target environmental factors.
After the water test, the sensor surface is wiped dry, and the main CHP detection test begins immediately. The moment the leak point sensor comes into contact with the CHP liquid, the response is extremely fast.
Result: Immediate alarm activation. As soon as the sensor touches the CHP liquid, the leak alarm system is triggered within 2 seconds. A sharp alarm sound and flashing red warning light indicate a hazardous chemical leak condition without delay. Starting from an initial sensor value of 1.0483, the reading quickly rises above the alarm setpoint of 2.0483, demonstrating fast response performance that can help secure valuable reaction time in critical industrial environments.
This short performance test clearly shows that the YHSP-SA is more than a simple detector. It is a practical industrial safety solution designed for selective and reliable liquid leak detection. By reacting rapidly to CHP while remaining stable in the presence of water, the sensor provides the combination of speed, selectivity, and operational reliability required for chemical plants, semiconductor facilities, and other high-risk industrial sites.
