FAQ：
1. What types of gas can the SR-908NSZ detector monitor?
The SR-908NSZ is designed for LPG gas leakage detection using a reliable catalytic combustion sensor. Please confirm the required target gas and alarm parameters before bulk ordering.
2. What power supply options are available?
The detector supports AC 90–240V, 50–60Hz input. An optional 9V rechargeable battery version is also available for projects requiring backup power.
3. How does the detector alert users to an LPG leak?
When the gas concentration reaches the alarm level, the detector activates an approximately 85 dB audible alarm, human voice prompts and a flashing red LED indicator.
4. Does the SR-908NSZ display real-time gas concentration?
Yes. The detector displays gas concentration in PPM, allowing installers and users to monitor gas levels and identify potential leakage risks more clearly.
5. Is OEM or ODM customization available for wholesale orders?
OEM and ODM services can be discussed for bulk orders, including branding, packaging, manuals, plug types and selected functional configurations. Customization options depend on order quantity and project requirements.
