Overview

The Uni-T UT3550 is a high-performance, handheld battery tester designed for professionals who demand the accuracy of benchtop instruments in a portable format. Engineered for precision, it provides exceptionally high resolution for both resistance and voltage measurements, making it an indispensable tool for quality inspection and maintenance across a wide range of battery types.

Featuring a robust USB Type C interface, the UT3550 allows for seamless remote control, data acquisition, and detailed analysis. Its dual-display design, featuring both a 3.5-inch LCD and a secondary OLED screen, ensures that all critical data is visible at a glance, even in challenging field conditions.

Why It Matters

Battery failure in critical systems like UPS or HVAC backups can lead to costly downtime or safety hazards. The UT3550 allows technicians to accurately assess battery health and internal resistance, identifying failing cells before they compromise the entire system. With its IP65 rating, this tester is built to withstand the rigors of industrial environments without sacrificing measurement integrity.
