Dual Current: 400A AC/DC Measurement.
High Precision: True RMS & 40mF Capacitance.
Safety First: NCV detection with audio-visual alarms.
Built to Last: Ruggedized design with a 1-meter drop protectio
The UNI-T UT203+ is a powerful upgrade in the UT200+ series, specifically designed to handle both AC and DC current measurements. While the UT202+ is limited to AC only, the UT203+ is a true all-rounder, making it indispensable for automotive technicians working with DC battery systems and industrial electricians dealing with complex motor controls.
Equipped with True RMS and a high-speed processor, this meter ensures accurate readings on non-linear signals and features a ruggedized build rated for CAT II 600V / CAT III 300V safety environments.
AC/DC Current Measurement: Unlike basic clamp meters, the UT203+ can measure up to 400A DC, making it perfect for solar installations and automotive diagnostics.
True RMS Technology: Provides precise measurements for both voltage and current, even when waveforms are distorted by modern variable frequency drives (VFDs) or UPS systems.
Non-Contact Voltage (NCV) Detection: Includes an integrated sensor with an LED indicator and buzzer to identify live AC voltage without touching wires.
Relative Mode (Zeroing): Features a dedicated REL button to zero out DC remanence or parasitic interference before testing, ensuring the highest accuracy for DC current.
High-Voltage Frequency: Capable of measuring frequency directly from the high-voltage source (up to 600V), a critical feature for generator and power grid maintenance.
Fast Sampling Rate: Refreshes the 4000-count display 3 times per second, allowing you to catch quick fluctuations in electrical systems.
Large 28mm Jaw Opening: Accommodates thick conductors while maintaining a slim, portable profile that fits easily in a tool belt.
