Technical Details
Compact Digital Multimeter for Everyday Testing
The UNI-T UT33B+ is a compact digital multimeter designed for basic electrical and electronics measurements. Its small form factor makes it convenient to carry in a toolbox, workshop, laboratory, or electronics workbench.
Voltage Measurement
The UT33B+ supports both DC and AC voltage measurement. DC voltage ranges extend up to 600V, while AC voltage measurement supports ranges up to 600V.
This makes it useful for checking batteries, DC power supplies, electronic circuits, and suitable AC electrical sources.
DC Current Measurement
The multimeter provides multiple DC current ranges, including measurements up to 10A. This allows users to measure current in suitable low-current electronic circuits as well as higher-current applications within the meter's specified limits.
Resistance Measurement
The UT33B+ supports resistance measurements up to 200MΩ, allowing users to check resistors, wiring, connections, and other resistive components.
Diode and Continuity Testing
Built-in diode testing helps users check semiconductor junctions and diode components.
The continuity function is useful for checking whether electrical connections, wires, switches, tracks, and connectors form a continuous circuit.
Easy-to-Use Interface
The manual-ranging design provides direct control over the measurement range. The 3½-digit LCD clearly presents measurement values for everyday testing and troubleshooting.
Suitable for Electronics Projects
The UT33B+ can be useful for:
- Electronics troubleshooting
- Arduino and microcontroller projects
- PCB testing
- Battery voltage checking
- Power supply testing
- Resistor measurements
- Continuity testing
- Diode testing
- Wiring checks
- Educational electronics laboratories
- DIY repairs
- General electrical measurements
Portable Design
With dimensions of approximately 108 × 53 × 36mm, the UT33B+ is designed to be easy to carry and store. It is powered by two AAA batteries, making it convenient for portable testing.
Safety Note: The UT33B+ is a measuring instrument, not a substitute for proper electrical safety procedures. Always select the correct function and range, use the appropriate test terminals, and stay within the meter's specified voltage/current and safety-category limits. Never measure voltage while the test leads are connected to a current input terminal.
