Import Bj-93d Stand-Combustible Gas Detector — Buy in wholesale FOB from Supplier in China

The BJ-93D is a stand-combustible gas detector designed for residential and light commercial environments, manufactured by Week Technology Ltd. in Shenzhen, Guangdong. It detects methane and carbon monoxide using a FIGARO semiconductor gas sensor, with alarm thresholds set at 1% to 25% LEL for methane and 50 to 300 ppm for carbon monoxide. The unit operates on AC220V plus or minus 15% and consumes less than 2W, making it economical for continuous operation.

The FIGARO semiconductor sensor at the core of this detector is a well-established technology in the gas detection industry, known for its compact size and reliable response to combustible gases. The BJ-93D offers dual output options: a DC12V pulse output capable of driving a shut-off valve, and a relay contact output for integration with alarm systems or building management panels. The operating temperature range spans minus 10 to 55 degrees Celsius, which covers typical indoor and sheltered outdoor conditions in most climates.

This detector suits importers serving property developers, facility management firms, and safety equipment distributors who need compliant gas detection for kitchens, boiler rooms, and small commercial premises. The dual-output flexibility allows integration with both automatic shut-off systems and central monitoring infrastructure. Buyers should confirm with Week Technology Ltd. whether the unit carries CCC certification for the Chinese domestic market, or whether EN 50194 or equivalent certification is available for export markets, as this will determine suitability for their target regions.

Week Technology Ltd. is headquartered at 16 Floor, Building 3, Zhongke Mansion, Shenzhen 518067, Guangdong, China. The supplier holds an imported tier_generation tier and a harbor trust_tier on the platform. The response rate is recorded as 0.00% with an average response time of 0 hours, which indicates the supplier has not engaged with inquiries through the platform's messaging system. Buyers should therefore initiate direct contact via the supplier's published channels and verify responsiveness before committing to orders.

The company profile does not disclose manufacturing facility details, employee count, annual revenue, client references, or specific quality management certifications such as ISO 9001. The listing focuses on the BJ-93D technical parameters rather than company history or production capacity. Importers should request a factory audit or third-party verification report, and confirm whether Week Technology Ltd. manufactures the detector directly or sources it from an OEM partner, as this affects warranty terms and spare parts availability.
