Features: Good insulation : the k type probe sensor is made of the fiberglass, which has good insulation, strong heat resistance and strong tensile strength. K type connector, -50C to 1200C temperature range. High sensitivity, durable in use. A great, small insertion thermocouple with a K-Type sensor, can be inserted in water or any other objects you'd like to measure. Has a miniature type connector that will work with digital K-type thermometers. As a kind of temperature sensor, K-type thermocouple is usually used in conjunction with display instruments, recording instruments and electronic regulators. Type K thermocouples can directly measure the surface temperature of liquid vapor and gaseous media and solids in various production temperature ranges. K-type thermocouples are usually composed of main components such as temperature sensing elements, installation fixtures and junction boxes. Package Includes: 1x Thermocouple Probe Specifications: Material:ABS+Metal Thermocouple: K-Type Temperature range: -50C to 1200C The length of the probe: approx. 10cm / 20cm / 30cm note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
