AI-Powered supplier vetting
SummarySconda Intelligent Technology Co., Ltd is described as a professional manufacturer of fire safety alarms and gas detection products, with production, measurement, and quality-control capabilities. It holds ISO 9001 certification, reports quality assurance and raw-material traceability, and has experienced R&D engineers and quality-control personnel. However, the available evidence shows no 3D software design, ODM, SDK, or popular-brand OEM services, and no new products during the past year. Customization from samples and designs is available. Overseas service infrastructure, inventory capability, and factory-subcontractor manufacturing contracts are absent. Financial information is limited to year labels without performance details, while after-sales procedures lack written records.
Supplier typeThe supplier is explicitly described as a professional and advanced manufacturer specializing in fire safety alarms, gas detection products, and related air-quality monitoring equipment. However, one assessment states that it is not a professional technical supplier, so its profile is stronger as a product manufacturer than as a technical-services provider.
CertificationsThe supplier reports holding ISO 9001 certification, directly evidencing a certified quality-management system.
R&D capabilityInnovation evidence is limited: the supplier reports no new products in the past year and does not provide ODM, SDK, or 3D software design services. It does report 21–30 years of total R&D engineer experience, but this alone does not establish current innovation performance.
Production capacityThe supplier describes advanced production lines, measuring facilities, manufacturing force, ISO 9001 quality management, and a stated peak- and off-season lead time within 15 workdays. Nonetheless, it reports no valid manufacturing-capacity contract with related subcontractors, no inventory capacity, and only one qualified supplier for the assessed service capability.
Customization capabilityThe supplier explicitly provides customization from samples and customization from designs. This supports product customization, although the same evidence confirms that it does not offer 3D software design services.
Product Q&A
Q:What is the sensor lifespan?
A:
The electrochemical sensor has a guaranteed lifespan of 10 years.
Q:How does the device indicate low battery?
A:
It triggers a low battery warning when voltage drops below 3.6V, indicated by a yellow LED flashing once.
Q:What are the alarm response times?
A:
Response times are 60-90 minutes at 50ppm, 10-40 minutes at 100ppm, and within 3 minutes at 300ppm.
Q:Does it have a self-check function?
A:
Yes, it features auto self-check capabilities to detect sensor faults and display errors on the LCD.
Q:What power source does it use?
A:
It operates on 3*1.5V AA batteries (not included) with a battery life of more than 1 year.
