Description
UNI-T UT222 2000A Digital Clamp Meters
The UNI-T UT222 clamp meter presents itself as a robust, yet ergonomically refined instrument, tailored to the hands of professionals who demand both precision and durability. Its housing, fashioned in a striking red-and-grey palette, combines high-impact plastics and textured grips, ensuring secure handling even in the most demanding environments. The unit’s compact dimensions belie its capacity: a broad, smoothly contoured jaw capable of enveloping large conductors and bus bars without imposing undue strain on the operator’s wrist.
At the heart of the UT222 lies its True RMS measurement circuitry, encapsulated within a thoughtfully arranged interface that balances clarity with comprehensive functionality. A generously sized, high-contrast digital display occupies the upper half of the front face, flanked by intuitive soft-touch buttons that facilitate seamless mode selection and data capture. Beneath the display, a subtle analog-style bar graph provides an at-a-glance indication of fluctuating readings, lending the device a tactile immediacy alongside its digital precision.
The clamp mechanism itself is engineered for smooth operation: a spring-loaded jaw that opens and closes with minimal effort, yet locks steadily in position to safeguard against drift during measurement. The hinge assembly incorporates reinforced metal components, marrying the resilience needed for frequent field use with the precision alignment required for accurate current sensing. Tempered by careful attention to balance and weight distribution, the UT222 feels neither top-heavy nor awkward, even when clamped around large-diameter conductors.
A rubberized protective boot encases the lower portion of the instrument, adding a further layer of impact resistance and insulating the user from accidental contact with test leads. The overall form factor is compact without sacrificing readability; generous display angles and backlighting ensure that measurements remain visible under low-light conditions or in confined spaces.
Taken together, the UT222 embodies a harmonious blend of form and function: a clamp meter that communicates reliability through its tactile feedback, visual clarity, and rugged aesthetic, while quietly delivering the level of performance demanded by today’s electrical professionals.

- Inrush current measurement to capture peak startup currents.
- Auto-ranging for seamless switching across measurement ranges.
- Data Hold and MAX functions to freeze or capture peak values.
- Analog-style bar graph for quick visual trend indication.
- On-board data storage to record readings for later review.
- MIN / I-OUT function for minimum-value capture and output current measurement.
- Relative (Δ) mode to zero out a baseline before measurement.
- Full-icon display showing active functions at a glance.
- Continuity buzzer and diode test for quick circuit checks.
- Duty-cycle measurement for pulsed signals.
- Low-battery indication to warn before power loss.
- High input impedance (≥ 10 MΩ) on voltage ranges to minimize circuit loading.
