GK Combustible Gas Leak Alarm
The GK Combustible Gas Leak Alarm is a dual‑sensor device that monitors both methane (CH4) and carbon monoxide (CO) in residential environments. It combines two detection functions in a single housing, reducing the space required for separate units and offering a cost‑effective solution. The alarm accepts AC220V ±15 % or AC110V ±15 % at 50‑60 Hz and also a DC12V supply, matching typical building electrical standards. Its compact design measures roughly 120 mm × 80 mm × 30 mm, fitting easily on walls or near fuel appliances.
The sensor module is rated for a service life exceeding three years, after which performance should be verified against the original calibration curve. Alarming thresholds follow industry practice: methane triggers at 10 % of the lower explosive limit, while carbon monoxide follows the EN 50291 standard. Optional valve or relay outputs allow integration with external safety systems, a common requirement in modern smart‑home installations. The unit operates reliably between - 10 °C and 50 °C, covering the temperature range of most indoor settings.
Typical buyers include home builders, property managers and small‑scale distributors who need a compliant gas safety device for new constructions or retrofits. Importers should confirm the minimum order quantity, packaging dimensions and preferred Incoterms before placing an order, as these details are not listed in the source data. Lead times and payment terms must be negotiated directly with the supplier to align with project schedules. Requesting a sample unit for on‑site testing can help verify compatibility with local wiring and mounting practices.

Sourcing GK Combustible Gas Leak Alarm from Henan Greeenland Tech Industrial Co. Ltd - China Import Guide
Before confirming an order, importers should request the latest conformity certificates, such as CE or any regional safety approvals, and obtain a functional sample for on‑site testing. Verifying the sensor’s calibration data and the alarm’s response characteristics against your project requirements reduces the risk of non‑compliance later in the supply chain.
Logistics details - including packaging dimensions, weight per unit, and the preferred Incoterm (FOB, CIF, etc.) - must be clarified with the supplier, as they are not disclosed in the listing. Shipping from Zhengzhou typically involves rail or sea freight to major Asian ports, followed by inland transport to the destination warehouse. Payment terms, such as a TT advance or a letter of credit, should be negotiated to match the buyer’s risk tolerance.
Quality assurance should include a pre‑shipment inspection by a third‑party agency, focusing on functional testing of the alarm, verification of voltage ratings and inspection of the enclosure for physical damage. Request a detailed inspection report and a copy of the factory acceptance test results before the goods leave the factory. Maintaining records of these documents supports smooth customs clearance and future warranty claims.
