The Fluke 1555 insulation resistance tester offers digital insulation testing up to 10 kV, making it ideal for testing high voltage equipment including switchgear, motors, generators and cables.
Data collection is easy using the Fluke Connect® wireless app. Remote operation lets you spend as little time as possible in potentially hazardous zones. Real-time trending shows a live graph on your phone, rather than a hard-to-read set of changing values. And you can create reports quickly, using pre-designed templates that you can customize with company logos. The 1555 insulation tester can now conduct the entire range of test voltages specified in IEEE 43-2000 with a best in class, 3 year warranty and CAT IV 600 V safety rating.
Other useful features:
• Automatic calculation of Dielectric Absorption (DAR) and Polarization Index (PI) with no additional setup
• Guard system eliminates the effect of surface leakage current on high-resistance measurements
• Selectable test voltages in 50 V steps from 250 V to 1000 V, and 100 V steps above 1000 V
• CAT III 1000 V, CAT IV 600 V safety rating
• Warning function alerts the user that line voltage is present and gives the voltage reading up to 600 V AC or DC for increased user safety
• Measurements can be stored in up to 99 memory locations, with each location assigned a unique, user defined, label for easy recall
• Long battery life gives the user over 750 tests between charges
• Large digital/analog LCD for easy viewing
• Capacitance and leakage current measurement
• Ramp function for breakdown testing
• Resistance measurements up to 2 TΩ

Key Features
• Quickly configure, start and stop tests on the 1555 remotely, a safe distance away from any operating, energized equipment, using Fluke Connect® and a smart phone
• Real time trending gives you easy-to-see visual cues, rather than hard to read, rapidly changing values
• Report creation using Fluke Connect desktop saves time and makes test results easier to understand
• Fluke Connect saves test results to the cloud for analysis and preventive maintenance

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.

Double your productivity or cut your calibration time in half
• Temperatures from –15 °C to 350 °C in one unit
• Two wells in each block for simultaneous comparison calibrations
• Rugged, lightweight, water-resistant enclosure

You’ve been asking for it and now we’re making it for you. The Model 9009 Industrial Dual-Block Calibrator lets you calibrate at hot and cold temperatures at the same time. Double your productivity or cut your calibration time in half—either way you look at it, your in-field temperature calibrations just got easier.

The Fluke 1535 and 1537 2,500 V Insulation Resistance Testers are engineered to simplify frontline troubleshooting whether you’re on the factory floor or working in the field at a solar installation. With user selectable test voltages from 250 V to 2,500 V and resistance measurements up to 500 GΩ these testers allow you to cover more workload with a single tool. Equipped with an intuitive user interface, a short circuit current of up to 5 mA and a CAT IV 600 V rating these portable high-voltage insulation testers can deliver rapid and stable resistance measurements no matter where you take them. The 1537 Insulation Resistance Tester also allows you to store measurements for later review or PC transfer, using the provided software.
• Selectable Voltage Tests: Tailor your tests with user-selectable voltages of 250 V, 500 V, 1000 V, and 2500 V to cover both industrial and solar applications.
• Extended Insulation Resistance Measurement: Reach up to 500 GΩ in insulation resistance measurement for a thorough analysis.
• Intelligent Calculations: Automatically calculate Polarization Index (PI) and Dielectric Absorption Ratio (DAR), minimizing the influence of environmental factors.
