The sensor attached to this thermometer is a kind of ultra-speed inductive bead-shaped thermocouple, suitable for many applications, but the maximum operating temperature does not exceed 250 (300 short-term) if you want to measure very high temperature, such as surface temperature, half For solid and liquid temperature, a hand-held thermocouple probe (such as TP-02A) or any type K (Nicr-NiAi) probe can be used
