What gases are applicable for this sensor?

It is applicable for natural gas, liquefied petroleum gas, and manufactured gas.

How does the flameout protection work?

When the flame goes out, the probe temperature drops, the thermoelectric potential disappears, and the solenoid valve resets to cut off the gas supply within 10-30 seconds.

AI-Powered supplier vetting

SummaryThermal International Co., Ltd. is identified as a private manufacturer/factory in Shenzhen, China, specializing in home-appliance heating elements, thermostats, switches, and motors. The supplier reports ISO 9001 certification, six production lines in one operational record, and a separate company description claiming ten assembly lines across three owned factories. It reports 11–20 R&D engineers, 11–20 quality-control staff, and product output information for hot plates, heating elements, and thermostats. Export activity began in 2008, with 51%–70% of total sales from exports and self-operated import/export rights. The supplier states that it supports on-site and third-party inspections, pre-sales consultation, timely delivery, and after-sales service. However, several areas—including outsourcing procedures, inventory, overseas operations, OEM/ODM, SDK-related R&D, quality traceability, customer cases, and current audit validity—remain unverified or explicitly unknown.

Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory, with a stated factory location in Shenzhen, China. Its reported production infrastructure includes six production lines in one record, while another description claims ten assembly lines across three owned factories, so the exact consolidated factory footprint is inconsistent but manufacturing status is clear.

CertificationsThe supplier reports ISO 9001 certification for its management system. This is explicit evidence of certification holding, although no certificate number, scope, or validity period is provided.

After-Sales capabilityThe supplier states that it provides personalized service from pre-sales consultation through after-sales service, with a sales team offering professional advice and timely delivery. These statements support the existence of an after-sales service commitment, although no service-level details or performance evidence are supplied.

Production capacityThe supplier reports six production lines in one factory record, while its company description states ten assembly lines across three owned factories. It also provides product-specific output quantities for hot plates, heating elements, and thermostats, which explicitly supports established production capacity, although the differing line counts should be clarified.
