Overview
The UNI-T UT33B+ is a high-performance digital multimeter that redefines the standards for introductory meters. It is part of the new generation UT33+ series, featuring an innovative industrial design that can withstand a 2-meter drop. This “B” variant is unique because it includes a Battery Test Function for 1.5V, 9V, and 12V batteries, making it an essential tool for homeowners and hobbyists checking everything from remote control batteries to UPS cells.
Key Features
Drop-Resistant & Rugged: Comes with a protective soft rubber case that protects the internals from workbench accidents and drops.
Battery Health Tester: Unlike other meters, this tests batteries under a small load to tell you if they are actually “Good” or “Bad.”
Bright LCD Backlight: Includes a clear, backlit display for working in dark DB boxes or under car dashboards.
Safety Certified: Rated for CAT II 600V, providing much better protection against surges than generic no-name meters.
Precision Probes: Comes with high-quality, flexible test leads that won’t snap or stiffen in cold weather.
