The Fluke 233 is an industry-first 2-in-1 True-RMS multimeter consisting of a main meter base and magnetic detachable wireless display, engineered for safe on-site measurement of confined cabinets, high-voltage incoming panels, motor interiors and hard-to-access live equipment. It adopts interference-resistant 2.4 GHz ISM wireless transmission; the display can be separated from the main unit and synchronously read measurements wirelessly up to 10 meters away, allowing technicians to stand clear of high-voltage test points and drastically reduce arc flash shock hazards.

With 6,000-count resolution, it supports full-range AC/DC 1000 V voltage, 0~10 A continuous current (20 A peak for 30-second short-term test), 10,000 μF large capacitance, 50 kHz frequency and K-type thermocouple temperature measurement for complete electrical diagnostics. Equipped with backlit large LCD and Min/Max/Avg trend recording to automatically capture elusive intermittent equipment fluctuations. The display features a built-in strong magnetic clip to attach to metal switchgears and equipment housings, freeing hands for easy probe operation.

Rated top industrial safety category CAT III 1000 V / CAT IV 600 V and fully compliant with IEC 61010 international electrical safety standards. Separate AA batteries power the main body and display, with auto power-off power saving delivering up to 400 hours single-charge runtime. It can be used wirelessly with detached screen or docked back to the base as a conventional integrated multimeter, serving as standard safety test gear for electricians, automation, new energy and HVAC maintenance technicians.
