• 58 mm jaw handles large or multiple conductors in high-current environments. 

• CAT IV 600 V, CAT III 1000 V safety ratings for enhanced protection. 

• In-rush current mode captures motor start-up surges accurately. 

• Fluke 355 adds 1000 V AC/DC voltage, 400 kΩ resistance, and continuity beeper. 

• Frequency measurement up to 1 kHz with 0.2% + 2 counts accuracy (5-100 Hz). 

• Large backlit display, MIN/MAX/AVG functions, and low-pass filter for noisy loads.

The Fluke 355 and 353 True-RMS Clamp Meters are robust tools designed for industrial and utility applications, handling high-current measurements up to 2000 A AC/DC and 1400 A AC with 1.5% + 5 digits accuracy (10 Hz to 100 Hz). Their 58 mm jaw accommodates large conductors, ideal for utilities, electrical contractors, and industrial technicians.

Both feature in-rush current mode for precise motor start-up surge capture, a CAT IV 600 V/CAT III 1000 V safety rating, and a low-pass filter for stable readings in noisy environments. The Fluke 355 enhances versatility with 1000 V AC/DC voltage (1% + 5 digits accuracy), 400 kΩ resistance, and a continuity beeper, functioning as a multimeter. Frequency measurements up to 1 kHz (0.2% + 2 counts accuracy) aid troubleshooting, while MIN/MAX/AVG functions and a backlit display ensure usability in low-light conditions.

With a 1-meter drop-tested, IP42-rated design, six AA batteries provide 100 hours of operation. The 355 includes TL224 Test Leads, TP2 Probes, and AC285 Alligator Clips, while both come with a C43 Soft Case. Backed by Fluke’s reliability, these 300x98x52 mm, 814 g meters are essential for demanding, high-power environments.
