UNI‑T UT 33+ Series
The UNI‑T UT 33+ Series redefines what compact digital multimeters can do. Encased in a durable housing that withstands 2 m drops, these mics deliver reliable measurement with CAT II 600 V safety.
With a clear 2000-count LCD, built-in beeper for continuity/diode tests, and probe holders, they’re ideal for fieldwork. Depending on model:
-
UT33A+: adds 2 nF–2 mF capacitance
-
UT33B+: includes battery test mode
-
UT33C+: features temperature up to 1000 °C with K-type thermocouple
-
UT33D+: offers non-contact voltage (NCV) detection.
These entry-level tools are perfect for electricians, hobbyists, and students seeking dependable functionality in a pocket-ready format.
