Hydrogen Fluoride (HF) leak detection, acid leak detection, and fast-response industrial leak sensors are essential in semiconductor, chemical processing, and hazardous liquid handling environments. In this test, we summarize the technical analysis and performance results of the YHSP-SAR sensor, which is designed for acid-based inorganic chemical solutions, and verify its fast response to Hydrogen Fluoride (HF) while remaining unresponsive to water.

1. Purpose and Test Configuration

The purpose of this test is to verify how quickly and accurately the YHSP-SAR leak detection sensor responds when Hydrogen Fluoride (HF), an acid-based inorganic chemical, is present. By comparing the response to normal water (H₂O), the test also confirms the sensor’s selective detection performance without false alarms.

• Test Equipment: Sensor for acid-based inorganic chemical solutions YHSP-SAR, test board, and precision stopwatch ⏱️

• Test Liquids: Hydrogen Fluoride (HF) 🧪 and normal water (H₂O) 💧

2. Initial Sensor Settings

For accurate liquid leak detection, the sensor’s initial output and alarm threshold were configured as follows.

• Initial Output (Normal State): 31 (stable standby condition)

• Leak Detection Threshold: 1000 (when the sensor output reaches this value, the leak alarm is triggered immediately 🚨)

3. Water (H₂O) Response Test: Verification of Selective Non-Response

First, a test was performed to confirm that the leak detection sensor does not generate false alarms in normal water such as rainwater, condensation, or cleaning water.

• Procedure: The sensor was placed in the test container, water was poured in fully, and the response was observed for 30 seconds.

• Result: Even after 30 seconds, the sensor output did not reach the threshold of 1000, and no alarm was triggered. 🤫

• Technical Meaning: This confirms that the YHSP-SAR sensor has high selectivity, meaning it is designed not to respond to non-target liquids such as water, which greatly reduces the possibility of false alarms in real industrial environments.

4. Hydrogen Fluoride (HF) Leak Detection Test: Verification of Fast Response

Next, the actual response speed of the leak detection sensor was tested using Hydrogen Fluoride (HF), the target chemical liquid.

• Procedure: After completely removing water from the sensor and ensuring a dry condition, Hydrogen Fluoride (HF) solution was poured in and the response time was measured precisely.

• Result: As soon as Hydrogen Fluoride (HF) contacted the sensor, the output value rose sharply and exceeded the threshold of 1000 within 5 seconds, triggering the leak alarm immediately. 🔔

• Technical Meaning: This result demonstrates that the YHSP-SAR leak detection sensor provides ultra-fast response in hazardous chemical leak situations, helping operators secure critical reaction time and improve workplace safety.

5. Overall Conclusion: Reliable Leak Detection Performance

Through this performance test, the YHSP-SAR sensor, designed for acid-based inorganic chemical solutions, proved excellent performance by showing fast response within 5 seconds to the target chemical Hydrogen Fluoride (HF) and complete non-response to water. 👍

This leak detection sensor can serve as a highly effective safety device in semiconductor facilities, chemical plants, laboratories, and other industrial environments where precise chemical handling and fast leak detection are critical. 🛡️
