Testo 0628 0020 Pipe Wrap Probe Type K Thermocouple

Product Description

The TESTO 0628 0020 is a pipe wrap surface temperature probe designed for field measurements on pipes up to 4.7 inches in diameter. It uses a Type K thermocouple sensing element and attaches to the pipe surface via an integrated Velcro strap, eliminating the need for clamps or tape during setup. A 4.9-foot cable connects the probe head to a compatible data logger or meter, giving technicians the reach needed to take readings without positioning the instrument directly at the measurement point. HVAC technicians, plumbers, and refrigeration service pros use this probe wherever quick, repeatable pipe surface temperature readings are required.

This probe is suited for residential and light commercial applications where surface temperature data is needed on suction lines, hot water supply pipes, condensate lines, or similar round pipe surfaces. The wrap-style design conforms to the pipe and holds the thermocouple element flat against the surface for stable contact. It is particularly useful during system commissioning, diagnostic troubleshooting, and energy audits where multiple temperature points must be logged over time.

Key Features

• Velcro strap attachment for fast, tool-free mounting on pipe surfaces
• Compatible with pipes up to 4.7 inches in diameter
• Type K thermocouple sensing element for broad temperature range coverage
• 4.9-foot cable provides working distance from the measurement point to the data logger
• Surface contact design delivers stable, repeatable readings on curved pipe surfaces

Compatibility

Designed for use with TESTO data loggers and meters that accept a standard Type K thermocouple input connector. Verify connector type compatibility with your specific TESTO instrument before ordering.

Installation Notes

Installation does not require pipe shutdown for the probe attachment itself, but the system should be in a known operating state before logging temperature data. Clean the pipe surface of debris, insulation residue, or moisture at the measurement point to ensure solid probe contact. A licensed HVAC technician or plumber should interpret readings in the context of system design parameters. Do not exceed the probe's rated maximum pipe diameter or bend the cable sharply at the probe head connector.
