TI51S-J fixed infrared thermometer is a high-tech product that applies military infrared detection technology (rocket combustion gas temperature measurement) to the industrial field. It has been widely used in steel, steel wire, coking, metallurgy, furnaces, chemical industry, rubber, plastics, glass, electric power, heat treatment and other industries.
The TI51S-J is a fixed‑type infrared thermometer designed for high‑temperature measurement in industrial processes such as steelmaking, metallurgy, and chemical production. It features a high optical ratio, adjustable emissivity, and fast response time for accurate temperature reading.
The manual provides technical parameters, wiring options (0‑20 mA, RS‑232, RS‑485), power requirements, and environmental limits, as well as contact information for the manufacturer. This manual is written in Chinese.
