📑 Technical Summary
This post presents an Octyl Mercaptan (NOM) leak detection test using an explosion-proof electronic point leak detection sensor for organic solvent leak monitoring. The test was conducted with NOM (Normal Octyl Mercaptan) provided by Kumho P&B Chemicals in Yeosu. The results confirmed excellent selectivity, showing no response to water and an alarm within 2 seconds when the sensor came into contact with the target organic solvent.

📋 1. Test Overview
-
Sensor Model: YHSP-SA-Ex (Explosion-Proof Point Sensor / Electronic Leak Detection Sensor)
-
Test Material: NOM (Normal Octyl Mercaptan, supplied by Kumho P&B Chemicals in Yeosu)
-
Reference Sample: Water (to simulate rainwater or moisture conditions)
-
Settings:
-
Initial Sensor Value: 1.07
-
Alarm Setpoint: 2.00
-
🧪 2. Main Test Procedure and Results
TEST 01. Water Response Test (False Alarm Verification)
To confirm whether the sensor might falsely react to rainwater, cleaning water, or condensation in the field, the sensor was immersed in water.
-
Procedure: The sensor was immersed in a beaker filled with water for approximately 30 seconds
-
Result: No Response (Normal)
-
There was no change from the initial value of 1.07, and no alarm was triggered.
-
👉 Conclusion: The sensor clearly distinguishes water from target organic solvents, proving stable performance with no false alarm in wet or humid environments.
-
TEST 02. Chemical Leak Detection Test with NOM
The response speed and accuracy of the sensor were evaluated under an actual chemical leak scenario using NOM.
-
Procedure: After removing moisture, the sensor was immersed in a dish containing NOM
-
Result: Immediate Response (Alarm)
-
Within 2 seconds after immersion, the sensor value exceeded the alarm setpoint of 2.00 and triggered an immediate alarm.
-
👉 Conclusion: The sensor showed ultra-fast response when exposed to the target organic solvent, demonstrating reliability for securing critical response time in hazardous leak situations.
-
💡 3. Key Takeaways
This test confirmed that the YHSP-SA-Ex leak detection sensor delivers the following key advantages.
-
Excellent Selectivity: No response to water, helping prevent false alarms caused by rainwater, wash water, or condensation.
-
Ultra-Fast Response: Immediate alarm within 2 seconds when exposed to target organic solvents such as NOM.
-
Explosion-Proof Design: Safe for use in hazardous industrial environments where explosion protection is required.
