## Questions & Answers

**Q: Is the PT520A suitable for continuous monitoring?**
A: No, the PT520A is a handheld, portable combustible gas leak detector, designed for periodic detection of gas leaks. It is not intended for continuous monitoring and should be used only to localize the source of a leak during routine checks.

**Q: Why do I choose gas leak detectors with gooseneck?**
A: With gas leak detectors with probe, you could detect the leaks in hard-to-reach areas. Besies, gas leak detectors could protect your life by prventing potential dangers suc as fires or explosions and alerting the presence of toxic gases.

**Q: Where could I use TopTes PT520A gas leak detectors?**
A: In most hard-to-reach leaks, you could use TopTes PT520A to detect. Besides, natural gas pipelines, gas stoves, ovens, funaces, water heaters, gas storage tanks or gas lines are the most common places for gas leaks.

**Q: Why does the TopTes PT520A need to warm up for 30 seconds?**
A: Allow the 30-second warm-up to finish in clean, fresh air so the sensor can stabilize and deliver accurate readings. Warming up in an environment with gas present may affect the sensor and lead to inaccurate or delayed detection.

**Q: Does a slower response time of the PT520A during testing mean my device is defective?**
A: No. Variations in airflow, distance, angle, or gas movement can cause one detector to respond slightly sooner or later. This is normal, not a defect. For best results, keep the probe 1–5 cm from the leak point and move it slowly.
