Fluke 80BK-A Bead Wire Temperature Probe measurement tool

SKU CH-9SRW-MPVCQ

Type K thermocouple bead probe measures air or surface temperature from -40 to 500 °F with a 3 ft cable and banana plug

  • Type K thermocouple covers -40 °F to 500 °F
  • 3 ft cable keeps the meter away from heat
  • 5/32 in bead fits tight surface gaps
  • Banana plug works with standard DMM inputs
  • Measures air, liquids and surfaces with one probe

Bead-wire thermocouple probe

The Fluke 80BK-A is a Type K bead-wire temperature probe built for air and surface measurements. It connects via a standard banana plug to compatible meters and instruments. The 3 ft cable gives flexible reach in tight panels or ductwork. It suits technicians who need a fast-response, general-purpose sensor.

Temperature range and headroom

The probe measures from -40 degrees to 500 degrees Fahrenheit, which is -40 degrees to 260 degrees Celsius. It comfortably covers HVAC diagnostics, automotive exhaust checks and electronic component testing. Above 500 degrees Fahrenheit the Type K wire reaches its specified limit and accuracy cannot be assured. The small 5/32 in bead offers quick thermal response but limited mechanical protection.

Type K interface limits

The banana-plug connection fits most Fluke and industry-standard meters that accept Type K thermocouples. No cold-junction compensation or linearisation is built into the probe itself; the meter must provide it. The bare bead is not suited for immersion in liquids or corrosive atmospheres. Users requiring rugged sheathing or higher-temperature capability need a different probe style.

Questions about this item

Will the 80BK-A probe's banana plug connect directly to my older Fluke multimeter?

The 80BK-A uses a standard banana plug compatible with Fluke meters that accept Type K thermocouple inputs, so it fits most legacy models without an adapter.

How can I verify the 80BK-A is reading accurately after I plug it in?

Insert the bead tip into an ice bath; the display should show 32 °F or 0 °C, confirming the Type K junction and meter are working together correctly.

Does the 80BK-A package include the meter or any extra accessories?

Only the bead wire probe with its 3 ft cable and banana plug are supplied; a compatible Fluke multimeter or thermometer must be purchased separately.
