Type K Surface Thermometer Probe

Type K Surface Thermometer Probe: Precision for Surface Measurements

The Type K thermocouple is widely recognized as the most common general-purpose thermocouple, valued for its broad temperature range and stable performance. Specifically designed for surface temperature measurements, this probe offers a sensitivity of approximately 41 µV/°C, making it a reliable choice across numerous applications.

Key Features & Specifications:

• Application: Standard surface temperature measurement.
• Temperature Range: Engineered to operate efficiently within a range of -50°C to +400°C (-58°F to +752°F). This specific range is ideal for many industrial and laboratory surface contact applications.
• Construction:
  • Handle Length: 4 inches (102 mm)
  • Probe Length: 8 inches (203 mm)
  • Probe Diameter: 13 mm
  • Max Cord Length: 45 inches
• Wiring Standard: Type K thermocouples adhere to a standard color code: Yellow (+) and Red (-).

Why Type K for Surfaces? Type K probes are excellent for quick, accurate surface temperature readings due to their robust construction and the wide operating range of the underlying thermocouple alloy. They are commonly used in HVAC, plastics processing, food service, and industrial maintenance for monitoring pipe temperatures, mold surfaces, and other flat or curved areas.

Comparison with Type J (for context): While Type K offers a broader general range (up to 900°C for the thermocouple type, though this specific probe is limited to 400°C), Type J thermocouples are characterized by a slightly higher sensitivity (around 50 µV/°C) but a more restricted upper-temperature limit, typically around +400°C. Type J wires are standardized as White (+) and Red (-). For surface applications, both can be used, but Type K's versatility often makes it the preferred choice.
