Thermocouple wire k type 2 wire length 100 meters

Description

• Type: K (Chromel-Alumel).
• Length: 100 meters (often sold in 100m rolls).
• Conductors: 2-core, typically 0.2mm, 0.4mm, or 0.5mm diameter.
• Insulation: PTFE (Teflon) or Fiberglass are common for heat/chemical resistance.
• Color Code: Red (Positive/KP) & White (Negative/KN).
• Temperature Range: Varies with insulation, but often -75°C to +260°C (PTFE) or higher for fiberglass.
• Shielding: Often includes metal shielding (braid/screen) for noise reduction, noted as “PT100 shielded” in listings. 
• Usage Note: This is usually compensation wire , used to extend the signal from a thermocouple sensor to a controller, maintaining accuracy over distance.
