Import 220v And 12v Optional Gas Leak Detector — Buy in wholesale FOB from Supplier in China

The SR-902 Gas Leak Detector is a dual-voltage safety detection device capable of operating on either AC 220V or DC 9-16V power supplies, providing flexibility for various installation environments. This detector automatically resets after alarm activation and utilizes an MCU (microcontroller unit) processing system for intelligent gas detection. The sensor features high stability and low power consumption characteristics, making it suitable for continuous monitoring applications in residential, commercial, and light industrial settings.

The device detects both natural gas (methane) and LPG (propane-butane mixtures) using semiconductor sensor technology with SMT (surface mount technology) construction for reliability. The detector operates within a temperature range of -10°C to +50°C and can function in humidity conditions up to 95% relative non-condensing humidity. Alarm triggering occurs at 10% LEL (Lower Explosive Limit) concentration, which represents one-tenth of the concentration at which the gas-air mixture becomes explosive.

The alarm output options include relay output with both normally closed and normally open contacts, RF signal transmission for wireless alerting, and local sound and flash alarm at volumes exceeding 85dB/m. Network output capability allows integration with building management systems for centralized monitoring. The compact dimensions of 70mm length by 40mm width by 110mm height facilitate installation in space-restricted locations. B2B buyers in property management, industrial facility safety, and building automation sectors commonly procure these detectors.

The Sumring Company is a safety detection equipment supplier based in Shenzhen, Guangdong Province, China, located at Pingji Road, Shenzhen 518000. The company is listed with a harbor trust tier on the platform. The supplier specializes in gas detection and safety alarm devices, with the SR-902 representing one product in their gas leak detector lineup. Company history, employee count, and production capacity details are not disclosed in the listing.

The listing indicates the supplier offers the SR-902 with auto-reset functionality and multiple alarm output options including relay, RF, and network connectivity. Response rate and average response hours are listed as zero, which may indicate limited recent platform activity. Buyers should verify current product certifications and manufacturing capabilities directly, as the listing does not specify quality management system certifications or export compliance documentation.
