• OpenJaw™ design: measure current without breaking the circuit

• Tester automatically selects AC or DC voltage, up to 1000 V

• Work in tight spaces with detachable Slim Reach probe tips

The Fluke 1503 is a great choice for basic residential and commercial electrical insulation testing. This rugged, compact tool fits in the palm of your hand. The 1503 is the same form factor as the Fluke 1507 but with a few less features. You can count on it to handle the most common tests at a most affordable price. Additional features, like the remote probe, reduce the time needed to perform repetitive testing.
Other useful capabilities:
• Measures AC/DC voltage from 0.1 V to 600 V
• Includes auto-discharge of capacitive voltage for added user protection
• Provides lo-ohms earth-bond continuity (200 mA)
• Simplifies repetitive or hard-to-reach testing with the remote test probe
• Saves battery power with auto power off
• Presents results on a large, backlit display
• Features CAT IV 600 V overvoltage category rating
• Comes with remote probe, test leads, test probes, alligator clips, and one-year warranty
• Accepts optional Fluke TPAK magnetic hanging system to free your hands for other work
• Runs on four AA alkaline batteries (NEDA 15 A or IEC LR6) for at least 1000 insulation tests

Key Features
• A rugged, compact insulation resistance tester for residential and commercial electricians
• Performs insulation tests from 0.01 MΩ to 2000 MΩ
• Offers two insulation test voltages: 500 V and 1000 V
• Includes live circuit detection to prevent insulation test if voltage >30 V is detected
• Measures resistance from 0.01 Ω to 20.00 kΩ

The Fluke 50 Series II contact thermometer offers fast response and laboratory accuracy (0.05% + 0.3°C) in a rugged hand test kit.

IR thermometer with type K thermocouple capability



Lighten up your toolbox. The Fluke 561 contact and IR thermometer combines the temperature measurement functionality needed by industrial, electrical and HVAC/R professionals, all in one tool. It also measures infrared and contact temperature, eliminating the need to use separate test equipment. Fast, efficient and easy to use, saving you valuable time and effort.



With the Fluke 561 infrared thermometer , you can also take contact and ambient temperature measurements in the way that suits you best. Use an IR thermometer to instantly measure hot, moving, electrified and hard-to-reach objects. Inspect motors, insulation, circuit breakers, radiant heat, pipes, corroded joints, and cables. Plus, scans for ducts, and other hard-to-reach objects, right from the floor. Just leave your ladder in the truck. You can use the flexible and handy Fluke 561 scanner tubing, or plug in any thermocouple probe with the industry standard mini-type K connector you already have to measure superheat or internal temperature.
