Flat wall surface temperature NTC probe, -58 to +176 DegF, 9.8 ft cable

The Testo flat wall surface NTC temperature probe is specifically designed for measuring surface temperatures on walls, floors, and building structures - a key measurement for identifying moisture ingress, thermal bridging, and building envelope deficiencies. Its compact, flat measuring head enables access to confined spaces and restricted locations where conventional probe geometries cannot make reliable contact. The NTC sensor element provides precise temperature readings across a measurement range of -58 DegF to +176 DegF (-50 DegC to +80 DegC). The extra-long 2.79-meter (9.8-foot) cable allows the operator to position the instrument at a convenient height while measuring at lower wall surfaces. The MiniDin connector ensures secure, compatible connection to compatible Testo measuring instruments. An essential probe for building diagnostics, energy auditing, and HVAC performance assessment workflows.
