Fast-Response Disposable Thermocouple: Precision in Seconds

Introducing our premium Single-Use Thermocouple, engineered for rapid and accurate high-temperature measurements in demanding industrial environments. Ideal for molten metal processing (e.g., steel, aluminum), this thermocouple delivers laboratory-grade precision with unmatched speed.

Key Features:

1. Ultra-Fast Measurement

Achieves temperature readings within 4–6 seconds 10, minimizing process interruptions and enhancing efficiency.

2. High-Temperature Capability

Withstands extreme heat up to 1,800°C, suitable for harsh conditions like furnaces, foundries, and ladles. 

3. Plug-and-Play Simplicity

Pre-assembled with a protective paper tube; simply attach to a compatible thermocouple gun, immerse into the medium (300–400 mm depth), and read results instantly. 

4. Optimized Safety & Consistency

Disposable design eliminates cross-contamination risks and ensures every measurement starts with a fresh, calibrated sensor. Applications: Liquid steel temperature monitoring Non-ferrous metal casting Quality control in metallurgy
