A Quick Response Thermocouple (QRT) is an ultra-fast temperature sensing assembly engineered with low thermal mass and specialized junction geometries to detect rapid thermal transients. Manufactured by Aavad Instrument, QRT sensors achieve time constants (τ₀.₆₃₂) as fast as 0.05 seconds across operating temperatures from −200°C to +1250°C, making them suitable for dynamic surface, gas-flow, and liquid-processing applications.
