Fluke 337 TRMS Clamp On Meter



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 (on most models) is easy-to-see 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
