Testo 0554 1202 Probe Extension Hose 2.8 Meters

Product Description

The TESTO 0554 1202 is a probe-to-instrument extension hose designed to extend the reach between a compatible Testo measuring instrument and its attached probe. At 2.8 meters in length, this hose gives technicians the flexibility to position a probe in hard-to-access locations while keeping the instrument within comfortable reading distance. Licensed HVAC technicians, refrigeration mechanics, and service professionals working in tight mechanical rooms or elevated equipment installations will find this extension useful during diagnostic and commissioning tasks.

This extension hose is suited for service scenarios where the standard cable length between probe and instrument falls short. Typical applications include measurements inside ductwork, at rooftop equipment, or in confined mechanical spaces where the technician cannot position the meter directly adjacent to the measurement point. It connects inline between the probe and the Testo instrument without requiring additional tools or adapters beyond the compatible connectors already on the probe and instrument.

Key Features

• 2.8-meter length provides extended reach between probe and instrument
• Inline connection design — installs between compatible probe and Testo measuring instrument
• Improves access to confined or elevated measurement locations
• Maintains the existing probe-instrument signal path without modification

Compatibility

Designed for use with compatible Testo measuring instruments and their corresponding probes that accept an inline extension hose connection. Consult the Testo instrument documentation to confirm connector compatibility before installation.

Installation Notes

This extension hose should be installed by the technician prior to taking measurements — power down or place the measuring instrument in standby before connecting or disconnecting the hose to avoid signal interruption. Ensure all connectors are fully seated before beginning a measurement session. Do not exceed the bend radius of the hose during use, and store coiled loosely to prevent kinking or connector damage.
