UNI-T UT33B+ Palm-Size Digital Multimeter (2000 Counts) – Battery Testing Multimeter with LCD Backlight & Drop-Proof Housing

Overview 

The UNI-T UT33B+ is an efficient, palm-sized digital multimeter engineered with a dedicated battery testing mode (1.5V, 9V, and 12V cells). Tailored for electricians, automotive battery technicians, and electronics hobbyists, this generation-plus meter delivers 2000-count resolution, ergonomic drop-proof rubber armor, and an upgraded LCD display with a bright white backlight. Alongside precise AC/DC voltage, current, and resistance measurements, the specialized battery load test function allows technicians to check real-world cell health under load rather than just measuring idle open-circuit voltage.

Key Features 

• Dedicated Battery Test Mode: Features specialized voltage load ranges for quickly testing 1.5V, 9V, and 12V batteries under simulated load conditions.

• 2000-Count High-Contrast Display: Clear digital LCD screen equipped with a bright backlight for effortless reading in dim repair shops and tight spaces.

• Rugged Drop-Proof Armor: Thick protective rubber casing absorbs accidental drops from up to 2 meters, safeguarding internal circuitry against harsh field environments.

• Comprehensive Electrical Suite: Accurately measures DC/AC voltage up to 600V, DC current up to 10A, resistance up to 20MΩ, diode checks, and continuity buzzers.

• Ergonomic Stand & Lead Clips: Built-in tilt stand and rear test lead holder make benchtop testing and storage convenient.

• Smart Energy-Saving Mode: Auto power-off feature extends battery life during long diagnostic sessions.
