Need more hours in your day?

Save time by NOT breaking the loop on 4-20 mA signal measurements.

Are you spending time:

  • Taking mA measurements by removing a wire and breaking the loop
  • Calling the control room to isolate a loop
  • Testing analog input/output on a console
  • Troubleshooting devices with mA inputs and outputs

Versatile and rugged tools for applications with high currentsConfidently take reliable readings with the True-rms, Fluke 355 and 353 digital clamp meters; the tools of choice for high current clamp-on amp meter measurement up to 2000 A. The extra-wide jaw easily clamps around large conductors, typically found in high-current applications. The extra rugged design and CAT IV 600 V, CAT III 1000 V ratings add an extra element of user 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 an ideal clamp meter for utilities, electrical contractors and industrial service technicians.

  • Reliably handle a wide range of high-current applications with 2000 A ac + dc true-rms, 1400 A ac, and 2000 A dc
  • 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
  • High voltage measurement of 1000 V ac + dc true-rms, 600 V ac, and 1000 V dc allows the user to perform multiple tests with only one tool (355 only)
  • Resistance to 400K ohms coupled with a continuity beeper provide the convenience of a multimeter in a clamp meter. (355 only)
  • 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
  • Use the low-pass filter to smooth out noisy loads and stabilize readings

The Fluke 360 leakage tester is a rugged and accurate solution for leakage current measurement.

Ideally designed for non-invasive checks of insulation condition, the Fluke 360 leakage meter allows you to perform tests without powering down the installation or disconnecting equipment – saving you time, without compromising on quality or safety.

The unique jaw design of the Fluke 360 AC Leakage Current Clamp Meter eliminates the influence of adjacent current conductors, and minimizes the effects of external magnetic fields, even at low currents. This allows you to perform accurate and reliable tests in today’s crowded electrical environments. The tough and high-quality jaw design of the Fluke 360 leakage tester guarantees high stability for long-term repeatability and durability.

  • Measurement of leakage current with 3 mA range and 1 µA of resolution, for accurate monitoring of insulation erosion
  • Broad range of measurement, from 1 µA up to 60 A, for all installation needs
  • Advanced shielding to ensure accurate results when measuring near other conductors
  • The high durability clamp construction can withstand over 50,000 operations, added ruggedness that extends the life of your leakage clamp.
  • Easy-to-carry, pocket-sized leakage current tester with wide 40 mm (1.5 in) jaw size
  • Handy “Display-Hold” button for capturing leakage current readings in hard-to-reach places
  • Auto power-off, with warning buzzer, saves battery life
  • Conformance to IEC1010 and EMC standard for confident measurements
  • Meets all of the applications and performance classes in safety standard VDE0404-4 and VDE0702 for leakage current and differential current measurement of electrical appliances

Reduce downtime – Find leakage currents without taking equipment offline

The Fluke 369 true-rms leakage current clamp meter helps users detect, document, record and compare leakage current readings over time as a means of preventing unplanned downtime, and identifying intermittent GFCI and RCD trips, all without taking equipment off line.

The Fluke 369 has an oversize 61 mm jaw for work with extra-large conductors. The clamp’s jaw is fully shielded to accurately capture very small leakage signals, and to minimize external electromagnetic interference.
