Fluke 80PK-1 Bead Wire Temperature Probe

Type: K Special Grade (Chromel vs Alumel)

Measurement Range: -40°C to 260°C (-40°F to 500°F) continuous

Accuracy (with respect to NBS tables for Special Grade): ±1.1°C (2.0°F) over the range of 0°C to 260°C (32°F to 500°F) Typically within 1.1°C (2.0°F) of NBS Tables over the range of -40°C to 0°C (-40°F to 32°F)

Output: 25°C (77°F) = 1.00mV (reference junction at 0°C)
