Feature: 1. UNIVERSAL JACK: The thermocouple temperature meter has a universal K J jack and can use a K J plug for easy insertion and removal, convenient to use 2. UPPER AND LOWER LIMIT WARNING: Thermocouple temperature gauge sets the upper and lower remind thresholds. When the measurement is higher than or lower than the set threshold, the red background light on the screen will keep on warning; The factory default reminder values are 1300℃(high) and -200℃(low) 3. WITH BACKLIGHT: The Thermocouple temperature meter gauge is backlit and can be clearly seen in low light conditions. Also allow you to easily switch between ℃ and ℉ temperature units, providing flexibility to meet your preferences or regional requirements 4. ACCURATE AND PRACTICAL: Meter supports Type K probes for temperature measurement: digital type K thermometers are compatible with Type K thermocouple probes, which are widely used for their accuracy and versatility in measuring a wide range of temperatures 5.
