Weller K Air Thermocouple, 0.5 mm Diameter, 50 °C Max

This thermocouple is a Weller K-type sensor designed to measure air temperatures up to 50°C in controlled environments. It serves as a compact air probe for technicians and engineers who require responsive temperature sensing with a fine tip for localised readings. The product carries UPC approval and is intended as a direct replacement option for compatible instrument probes.

• K-type sensor offers wide compatibility with thermometry instruments
• 0.5mm probe tip provides precise, localised readings
• Air probe configuration supports non-contact ambient sensing
• Maximum measurable temperature 50°C prevents overheating errors
• UPC approval confirms adherence to specified acceptance criteria

• Suitable for monitoring ambient temperatures in labs
• Ideal for spot-checking electronics enclosures
• Used with handheld meters for HVAC diagnostics
• Can be used for process control in low-temperature assembly
• Used for verification of environmental chambers

The slender 0.5mm tip enables focused contact with small targets for accurate local readings.

It employs a K-type thermocouple element, which offers broad instrument compatibility and predictable voltage-to-temperature response.

No, it is specified for measurements up to 50°C and is therefore suited to low-temperature air monitoring rather than high-heat processes.

The unit is set up as an air probe, optimised for sensing surrounding gas temperatures rather than immersed or surface measurements.
