UT802 Bench Multimeter

Overview and High-Precision Measurement Engine

The UNI-T UT802 is a high-reliability, 4.5-digit benchtop digital multimeter specifically engineered for precision electrical testing, advanced research and development, electronic design verification, and industrial quality control. Built around a 20,000-count clear LCD with a dedicated backlight system, the UT802 yields fine resolution across a comprehensive array of measurement parameters. Engineering teams and calibration technicians can evaluate direct current voltage with a baseline accuracy of +/- (0.1% + 3 digits), enabling precise voltage rail verification, sensor output characterization, and power supply drift analysis in sensitive hardware and embedded processing systems.

Comprehensive Parameter Range and Hardware Architecture

Designed to serve as an all-in-one bench station, the UT802 measures AC and DC voltage up to 1000V, AC and DC current up to 10A, resistance up to 20Mohm, capacitance up to 200uF, and frequency up to 200kHz. Integrated specialized functions include transistor hFE parameter measurement, K-type thermocouple temperature sensing from -40 to 1000 degrees Celsius, diode testing, and fast-response continuity checks with an audible buzzer. Operating at a sampling rate of 2 to 3 updates per second with an AC bandwidth frequency response extending up to 1kHz, the unit reliably captures true sinusoidal and standard utility AC signals with minimal circuit loading errors.

Specification

Signal Integrity, Overload Protection, and Safety Engineering

To withstand demanding laboratory and production line environments, the internal PCB design integrates fast-acting ceramic fuses and complete overload protection across all input ranges. Input impedance on DC voltage ranges is maintained above 10Mohm, suppressing loading effect errors during low-current, high-impedance circuit analysis. The rugged benchtop enclosure features an integrated tilt-bail stand for ergonomically angled viewing, side accessory slots, and a top-mounted storage compartment for test leads, probes, and banana-to-alligator clip adapters, keeping the workspace organized and efficient.

Lab Workflow, Power Flexibility, and Industry Applications

Whether deployed in high-volume electronics manufacturing lines, telecommunications infrastructure testing, audio engineering laboratories, or university engineering faculties, the UT802 provides dependable measurement stability. The instrument supports dual power input modes, allowing continuous operation via AC mains power or portable deployment using standard internal batteries for field calibration stations. The combination of high count resolution, tactile rotary range switching, and stable benchtop grounding makes the UNI-T UT802 an indispensable tool for embedded systems troubleshooting and hardware verification.
