Q: How to set up the detector to make it ready to detect?

A: Turn on and wait for 30 seconds to warm up. Please keep in mind that the warm-up process should be performed in a known 'clean' environment to achieve accurate results.

Q: How close does the detector need to be to detect leaking gas from a natural gas pipeline?

A: Generally 1-5cm, depending on the severity and concentration of the gas leak.

Q: How can I tell what sensitivity the detector is currently at?

A: When the S button light is on, the detector is in high sensitivity mode; when the S button light is off, the detector is in low sensitivity mode.

Q: Does the alarm continue until the situation is resolved?

A: Yes, the alarm will continue to sound until the combustible gas concentration is below 5% of the lower explosive limit.

Q: Can the sensors be replaced?

A: We do not sell sensors separately. If you find that the sensor is no longer working within three years from the date of purchase, please get in touch with us.

Q: What is the difference between a gas monitor and a gas leak detector?

A: Gas monitors are used for continuous gas leak monitoring to monitor the air state in a large space, but they are unable to pinpoint the exact leak point. The gas leak detector is used to locate the source of the gas leak.
