Unit UT220 Digital Clamp Meter, AC 2000A, DC/AC 1000V/750V, 20MΩ, CAT III 1000V/CAT IV 600V

The Unit UT220 is a professional-grade digital clamp meter engineered for precise high-current measurements in demanding industrial environments. Capable of measuring AC current up to 2000A, this robust tool provides reliable performance for electrical diagnostics and maintenance. It features a large 60mm jaw opening, allowing for easy access to thick cables and busbars, while the integrated HOLD function ensures that readings can be captured and reviewed conveniently even in tight or poorly lit spaces.

Advantages

This clamp meter stands out due to its high current capacity and versatile measurement range, covering AC and DC voltage up to 1000V and 750V respectively. The device is built with safety as a priority, meeting CAT III 1000V and CAT IV 600V standards, which provides necessary protection when working on high-energy electrical systems. Its ergonomic design and clear digital display facilitate efficient operation, making it a dependable choice for professionals who require accuracy and durability in their daily tasks.

Suitable for

• Industrial electrical maintenance and troubleshooting
• High-current power distribution system diagnostics
• Commercial building electrical inspections
• Testing large-scale electrical machinery and equipment

This device may not be suitable for low-current electronics repair or micro-circuitry diagnostics where high sensitivity and precision at the milliampere level are required. Additionally, it is not designed for measuring DC current, which limits its utility in automotive battery testing or solar power system monitoring.

Key specifications

• AC Current range: up to 2000A
• DC Voltage range: up to 1000V
• AC Voltage range: up to 750V
• Resistance measurement: up to 20MΩ
• Jaw opening: 60mm
• Safety rating: CAT III 1000V, CAT IV 600V

How to use

To perform a current measurement, set the rotary dial to the appropriate AC current range. Press the trigger to open the clamp jaws and enclose a single conductor carrying the current. Ensure the jaws are fully closed for an accurate reading. For voltage or resistance measurements, connect the provided test leads to the input terminals and touch the probes to the target test points. Use the HOLD button to freeze the measurement on the screen when working in difficult positions.

What to consider before purchase

• Verify that the maximum current and voltage levels of your application fall within the device specifications.
• Ensure the 60mm jaw size is sufficient for the diameter of the cables you intend to measure.
• Confirm that the lack of DC current measurement capability meets your specific project requirements.

Usage recommendations

Always inspect the test leads and the clamp meter housing for any signs of damage before use. Ensure the device is set to the correct measurement mode before making contact with live circuits to prevent damage to the meter or injury to the user.
