This clamp meter is essential for professional electricians as it can measure current and voltage in wires easily in the most confined spaces.
This clamp meter is essential for professional electricians as it can measure current and voltage in wires easily in the most confined spaces.
The CM3289 is a True RMS rectifying 1000A AC clamp meter that features a broad operating temperature range of -13 to 149°F (-25 to 65°C), thin and compact clamp core and optional flexible current sensor that you can attach to let you get into the tightest spots.
