1. AstroAI Digital Clamp Meter Multimeter

AstroAI’s Digital Clamp Meter Multimeter features non-contact voltage testing with sound and light alarms. It accurately measures AC/DC current, AC/DC voltage, capacitance, frequency, duty cycle, resistance, diode, continuity and live wire tests. However, a potential annoyance is the inclusion of the small screw battery protection, rather than a slide-off cover. 

Key features:

• True RMS for accurate measurements on non-linear loads.
• Measures AC/DC voltage, AC current, resistance, continuity, capacitance, and more.
• Features a large backlit display for easy reading in low light conditions.
• Includes alligator clips.
• Comes with a lifetime technical support warranty.

2. Kaiweets Digital Clamp Meter

Kaiweets' Digital Clamp Meter multimeter can accurately measure AC/DC current, AC/DC voltage, frequency or duty cycle, resistance, and capacitance and also provides diode, continuity, and temperature tests. It provides true RMS for accurate measurements of non-linear loads, while its low input impedance helps prevent false readings due to ghost voltage. To measure the current, you need to clamp the meter around one of the wires (not the whole power cord). However, its non-contact voltage detection checks the electrical status by measuring EM field intensity without touching any wires. 

Key features

• Non-contact voltage detection and live function with sound and light alarm.
• Auto-ranging with a large, easy-to-read LCD.
• Detects standard and low voltage (12-1000V AC / 48-1000V AC).

3. Etekcity Digital Clamp Meter

The Etekcity Digital Clamp Meter is capable of measuring both AC current and AC/DC voltage, along with resistance and continuity and diode testing.  The clamp meter's design allows for the measurement of AC in conductors up to 26mm, alongside built-in voltage detection and overload protection. Its user-friendly features include data hold, maximum reading capture, and an easy-to-read large LCD. The inclusion of long metal prongs allows for easy insertion into plugs and secure contact with wires. Crafted from durable plastic and equipped with an intuitive dial, the meter is both sturdy and simple to operate. 

Key features:

• Measures AC current, AC/DC voltage, resistance, continuity, and diode testing.
• Built-in voltage detection features and overload protection.
• Easy-to-use interface with a large display.

4. Fluke 323 Clamp Meter

The Fluke 323 Clamp Meter offers electricians True RMS for accurate electrical testing, even in complex or enclosed environments. It measures up to 400A AC current, 600V AC/DC voltage, and 4kΩ resistance. Its slim design and large display make it easier to use while in confined spaces, while a CAT III 600 V and CAT IV 300 V safety rating are there to give you peace of mind. The meter comes with a two-year warranty and a carrying case.

Key features:

• True RMS sensing for accurate measurements.
• Measures AC current up to 400 amp, AC/DC voltage up to 600V, and resistance up to 4 kilohms.
• Slim, ergonomic design with a large, easy-to-read display.

5. Klein Tools Digital Clamp Meter

The Klein Tools CL800 Digital Clamp Meter offers True RMS technology for precise measurements. It measures AC/DC current, voltage, resistance, capacitance, frequency, duty cycle, and temperature, and includes diode and continuity testing capabilities. It features a built-in LED work light and a backlit display for low-light conditions, CAT IV 600V and CAT III 1000V safety ratings for high-voltage applications, and withstands drops up to 6.6 feet. The meter's design reflects feedback from electricians and includes a carrying pouch, test leads, a thermocouple with an adapter, and batteries.

Key features:

• True RMS for accurate measurements in all conditions.
• Measures AC/DC current, voltage, resistance, capacitance, frequency, duty cycle, temperature, and tests diodes and 
  continuity.
• Built-in LED work light
• Backlit display.
