Confidently take reliable readings with the true-rms, Fluke 353 Clamp Meter; the tool of choice for high-current measurements up to 2000 Amps. The extra-wide jaw easily clamps around large conductors typically found in high current applications. The rugged design and CAT IV 600V, CAT III 1000V 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 355 also measures voltage and resistance making this the most versatile tool for utilities, electrical contractors, and industrial service technicians.

Features

Reliably handle a wide range of high-current applications with
2000A ac + dc true-rms, 1400A ac and 2000A dc.
The large 58mm (2.3 in) jaw capacity is suitable for large or multiple conductors.
In-rush current measurement captures 'power-on' surge current with accuracy and repeatability.
High voltage measurement of 1000V AC + DC true-rms, 600V AC, and 1000V DC allows users to perform multiple tests with only one tool.
Resistance to 400K Ohms coupled with a continuity beeper, provides the convenience of a multimeter.
Accurately measure frequency up to 1kHz for optimum troubleshooting.
Quickly analyze readings using the MIN, MAX, and AVG functions.
A large backlight display allows for easy visibility in low-lit areas.
Use the display hold feature to capture readings even when the display cannot be viewed.
Use the low-pass filter to smooth out noisy loads and stabilize readings.
CAT IV 600V, CAT III 1000V rating for added user protection.
