Features: As a kind of temperature sensors, K-type thermocouple is usually used in conjunction with display instrument, recording instrument and electronic regulators. Type K thermocouples can directly measure the surfaces temperature of liquid for vapors and gaseous media and solids in various production temperature ranges. K-type thermocouples is usually composedly of main components such as temperature sensings, installation fixtures and junction box. This probes is used by most multimeters and temperature meter. Use K-type connection. It is protect by a material to protect it from extreme cold or heat. Banana-type plugs, plugs length 14mm, cable length 1 meter, temperature measurement ranges -50°C - 350°C. Good insulation : the k type probes sensors is crafted of the fiberglasses, which have good insulation, strong heat resistance and strong tensile strength. Specifications: Materials:ABS Length: Approx.100cm/39.37inch Package Includes: 1pcs Thermocouple Probes note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you donot mind befores you order. 2.Due to the differences between different monitors, the picture may not reflect the actual color. Thanks for your understandings.
