[Performance Verification] Instant Detection of Caustic Soda (Sodium Hydroxide) Leaks! Acid/Alkali Leak Detector YHSP-SAR Test

YooHanTech’s advanced acid/alkali dedicated leak detector, YHSP-SAR. This video demonstrates how quickly and accurately the sensor responds to leaks of caustic soda (sodium hydroxide, NaOH), a strong alkaline chemical widely used in industrial facilities. The test verifies the sensor’s ability to trigger an alarm immediately upon chemical contact and help prevent chemical leak incidents.

Step 1: False Alarm Prevention Verification (Water Response Test)

The first test medium is water. Even when fully immersed for 20 seconds, the leak sensor remains stable with no change in status. The green “normal” indicator confirms not only safe operation, but also the sensor’s selective detection that avoids reacting to rainwater or condensation. This intelligence reduces unnecessary false alarms and improves operational reliability.

Step 2: Instant Detection of Caustic Soda Leaks (Response Speed)

And then, the critical moment: the instant the sensor touches a 30% caustic soda (NaOH) solution.

A sharp leak alarm sounds and the red warning light flashes immediately.

The response is so fast it needs no stopwatch. The instant leak alarm upon contact reflects YooHanTech’s engineering focus on early warning, helping prevent even small leaks from escalating into major hazards.

Final Conclusion: Essential Safety Equipment for Chemical Leak Risk Control

In this short test video, the YHSP-SAR leak detector demonstrates exactly what it is built for: quiet stability during normal conditions and immediate warning at the first sign of danger. More than a detector, it is a practical tool to support chemical safety and improve on-site risk control.
