Uni-T UT203R is a compact digital clamp multimeter for quick installation checks and circuit diagnostics. It offers AC/DC current measurement up to 400 A without disconnecting wires, True RMS for more accurate results, and practical features such as NCV, Data Hold, and a backlit display for comfortable field work.
AC/DC current measurement up to 400 A without opening the circuit
The clamp jaws make it easy to measure AC and DC current up to 400 A directly on a conductor. Ideal for quick installation checks and on-site appliance diagnostics.
True RMS and NCV for more accurate and faster diagnostics
With True RMS, you get more accurate results even with non-sinusoidal signals. The NCV (non-contact voltage detection) function helps you quickly verify the presence of voltage without directly connecting test leads.
Backlit display and compact design for easy readings
The large backlit LCD makes it easier to read measured values even in poor lighting. A 28 mm jaw opening ensures easy clamping of conductors and comfortable handling.
The Uni-T UT203R digital clamp meter is a practical tool for electricians and home workshops. The clamp design allows safe, fast current measurement without having to open the circuit, saving time when checking switchboards, outlets, or appliances.
The multimeter measures AC and DC current and voltage, and also supports measurement of frequency, capacitance, and resistance. With functions for quick diagnostics, it is ideal for everyday service tasks.
