Thermocouple: K type (Ni-Cr/Ni-Al) 220mm (8.7") Length with Ceramic Sheath - TCK22

Features:

• K-type thermocouple for high heat applications at temperatures up to 1250^oC
• Measures room temperature - 1250^oC, Suitable for OTF-1200X Split Tube Furnace

Specifications: Length: 220mm, (8.7") Diameter of sheath: 8 mm , high purity Alumina Positive Material: Nickel-Chromium (this leg is non-magnetic) Negative Material: Nickel-Aluminum (this leg is magnetic) Wire diameter: 1.5 mm Lowest Temperature: -200 oC Highest Temperature: 1250 oC Minimum Std. Error: +/-2.2 oC

Application Note:

• If necessary, please check out K type thermocouple extension wire with mini male plug. Using compensating wires is equivalent to stretching them to keep them operating at a constant temperature. The advantages of using compensating cables are saving material costs and solving the problem of constant temperature, etc.
  
• There are 2 polarities for K-type thermocouple: positive and negative. Please check polarity of K type thermocouple before use. Wrong polarity may cause temperature measuring error.
• It is also easy to test the polarity of K type thermocouples. The negative wire is MORE magnetic than the positive wire. Just put a magnet up to each wire. One will be more magnetic than the other.
