  • Take a new look at current measurement

    With the striking design of the Fluke 330 Series Clamp Meters, there’s a new way for you make to current measurements. At how you use your tools, and how to get the results you need, faster and more conveniently. The result is a new, ergonomic concept, shaped to fit your hand and to access tight spots easily.

    Thanks to its True RMS and in-rush capabilities, the 335 Clamp Meter can accurately measure both sinusoidal and non-sinusoidal waveforms, and filter out noise to capture the motor start-up current exactly as a circuit protector sees it.

  • The 335 Clamp Meter features:

    • Three year warranty
    • True RMS clamp meter
    • Measure AC amps, AC/DC volts, ohms and motor start-up current
    • Large, backlit display is easy-to-see in less than ideal conditions
    • In-rush current function for measuring starting current for motors, lighting, etc.
    • Small body and jaws fit perfectly in your hand and into tight places
    • Handy ‘Display Hold’ button keeps measurements on the display
    • Meter controls are positioned so current measurements can be done with one hand (index finger on clamp opening lever and thumb on rotary switch)
    • Auto shut-off maximizes battery life so the meter works when you need it
    • Improved low current measurement accuracy for new microprocessor technology
