Fluke 80PK-8 Type-K Pipe Clamp Temperature Probe
The 80PK-8 Type K Thermocouple Pipe Clamp Temperature Probe is designed to reliably measure the temperature of pipes 1/4 in. (6 mm) to 1-3/8 in. (35 mm) in diameter, at temperatures between -29 °C and 149 °C (-20 °F and 300 °F), while retaining a long service life.
Type-k thermocouple for fast temperature and superheat measurements of pipe surfaces
Durable ribbon sensor
Measurement range: -29 to 149 °C (-20 °F to 300 °F) for pipe diameters from 6.4 to 34.9 mm
Accuracy: ±1.9 °C (±.3.4 °F). Surface measurement accuracy of ±1.9 °C includes ±1.1°C variation in alloy plus probe contact and shunting uncertainty of ±0.8 °C
Repeatability: ± 0.56 °C (±1 °F)
Output: @ 25 °C (77 °F) = 1.00 mV (Reference junction at 0 °C)
Seebeck coefficient: @ 25 °C (77 °F) = 40.50 μV / °C
Measurement time (time constant): 0.5 seconds (5 time constants = 1 complete step change, i.e. 2.5 seconds)
Maximum voltage rating: 24 V ac rms, or 60 V dc
