K-Type Thermocouple Probe for Harsh Environments

The Uei Test Instruments ATT29 is a bead-wire thermocouple probe built for air or surface temperature checks. It serves HVAC technicians, automotive specialists and industrial maintenance crews who need fast response on live systems.

Measures -40 to 950 °F with K-Type Output

The single specification that decides fit is the temperature span: -40 °F to 950 °F (-40 °C to 510 °C) via a standard K-type connector. Any application outside that window or requiring a different thermocouple type will not work with this probe.

Four-Foot Nylon Lead Enables Remote Access

The 4 ft white nylon-insulated wire lets the operator keep the meter clear of hot surfaces, moving parts or confined ducts. Without that reach, measurements on ceiling ducts, engine bays or deep enclosures become impractical or unsafe.

Questions about this item

What does the -40 to 950°F range mean when I clamp the bead onto a hot pipe?

The K-type bead will report temperatures from -40°F up to 950°F (-40°C to 510°C) as long as the wire insulation and the measured surface stay within those limits.

How does the K-type connector limit the readings I can get from my meter?

The probe ends in a standard K-type plug, so any meter with a K-type input can read it; the connector itself does not restrict the -40 to 950°F span.

Will the 4 ft wire reach inside a deep duct and still let the bead sit flat?

The 4 ft bead wire is flexible nylon-insulated cable, long enough for most duct or surface work while letting the bare bead make direct contact.
