Take a new look at current measurement
With the striking design of the Fluke 330 Series, we've taken a new look at the way you make 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. The series feature a large display that is backlit -on most models- so readings can be taken in virtually any lighting situation. Auto-shut-off maximizes battery life so the meter works when you need it. A choice of five models gives you the right functions for your measurements.

Clamp meters that fit the way you work
- Three year warranty
- 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)
- Large, backlit display is easy-to-see in less than ideal conditions
- In-rush current function (on most models) for measuring starting current for motors, lighting, etc.
- Auto shut-off maximizes battery life so the meter works when you need it
- Improved low current measurement accuracy from new microprocessor technology
- Five different models to meet your exact needs
