Fluke 80PK-11 Type K Pipe Clamp Temperature Probe, -30 to 105°C 2724500

HVAC technicians and industrial maintenance crews often need to measure pipe surface temperatures without shutting down the system. The Fluke 80PK-11 pipe clamp probe makes this straightforward: just clamp it onto a pipe from 6.4 mm to 38 mm in diameter and connect it to any Type K thermometer. The spring-loaded jaw ensures firm contact for stable readings, while the 1-meter PVC cable gives you room to work.

Key specifications

• Type K thermocouple with standard miniature connector
• Measurement range: -30 °C to 105 °C (-22 °F to 221 °F)
• Accuracy: ±2.2 °C or 2% of reading (0 °C to 105 °C); ±2.7 °C or 2.5% of reading (-30 °C to 0 °C)
• Pipe diameter capacity: 6.4 mm to 38 mm (0.25 in to 1.5 in)
• Cable length: 1 m (39 in), PVC insulated
• Probe handle/cable operating temperature: 0 °C to 50 °C (32 °F to 122 °F)
• Storage temperature: -20 °C to 60 °C (-4 °F to 140 °F)
• Relative humidity: 0% to 80% non-condensing

Why choose it

The 80PK-11 is built for reliable surface temperature measurements on pipes and tubes. Its spring-loaded clamp holds the sensor firmly against the surface, minimizing contact errors and ensuring consistent readings. The Type K connector works with a wide range of Fluke thermometers and other instruments that accept Type K thermocouples, so you can integrate it into your existing toolkit without adapters.

Ideal use cases

• Checking superheat and subcooling on HVAC lines
• Monitoring hydronic heating and cooling pipes
• Verifying process temperatures in industrial piping
• Balancing chilled water systems
• Diagnosing temperature issues in refrigeration circuits

Good to know

The probe is not intended for immersion in liquids or direct contact with live electrical circuits. For best accuracy, allow the probe to stabilize for a few minutes after clamping. The PVC cable is durable but should be kept away from sharp edges and extreme heat beyond the specified operating range.
