K-type Temperature Thermocouple with Metal Shield Insulation (1 Meter) A Type K thermocouple refers to any temperature sensor containing Chromed and Alumel conductors, that meets the output requirements as stated in ANSI/ASTM E230 or IEC 60584 for Type K thermocouples. This may be an immersion sensor, a surface sensor, wire, or another style of sensor or cable. Temperature Sensor, Shielded K Type Thermocouple High Accuracy for Control. Whereas a J Type Thermocouple is made up of iron and constantan, K type Thermocouples are composed of a nickel/chromium alloy (chrome) and a nickel/aluminum alloy (alumni) which gives them much better protection against oxidation and acidity than the iron limbs of the Type J Type K consists of two metal alloys Chromel (90% Nickel, 10% Chromium) and also Alumel (95% Nickel, 2% Manganese, 2% Aluminium and 1% Silicon). Due to the thermocouple having a Nickel base; this means that it has good corrosive resistance-meaning that it can be widely used in many applications and situations.

It has a temperature measuring range of 0 to 600 °C and features a K-type connector with an insulated wire. Packages Includes: 1 x K-type Thermocouple
