  • The large 58 mm (2.3 in) jaw capacity is suitable for large, or multiple conductors
  • CAT IV 600 V, CAT III 1000 V rating for added user protection
  • In-rush current measurement captures 'power-on' surge current with accuracy and repeatability
  • Accurately measure frequency up to 1 kHz for optimum troubleshooting
  • Quickly analyze readings using the MIN, MAX, and AVG functions
  • A large backlit display allows for easy visibility in low-lit areas
  • Use the display hold feature to capture readings even when the display cannot be viewed

Fluke Introduces a new line of Clamp meters which promise to surpass expectations, meaning the user can confidently take reliable readings with the true-rms. The Fluke 355/353 Clamp Meters; the tools of choice for high-current measurements up to 2000 A.

The Fluke 355 is designed with extra-wide jaw easily to clamp around large conductors typically found in high-current applications. The rugged design and CAT IV 600 V, CAT III 1000 V ratings, add an extra element of protection when taking high-powered measurements.

Accurate peak measurements can be taken using the in-rush current mode, ideal for motors and inductive loads. The Fluke 355's Sister Clamp meter, the Fluke 353, lacks the ability to measure voltage and resistance, however this makes it more affordable for those people who require a high quality product and do not require excess options. The functions of these two clamp meters easily makes the Fluke 353 and 355 the most versatile tool for utilities, electrical contractors, and industrial service technicians.
