True-RMS Digital Multimeter

The Fluke 179 True-rms Digital Multimeter is the industry-standard troubleshooting tool for electrical and electronic systems. This incredibly versatile multimeter makes a perfect front-line troubleshooting tool with an input protection rating of CAT III 1000 V, CAT IV 600 V. The built-in temperature measurement with the included thermocouple, analog bar graph and backlit digital display make it easier to take the measurements you need.

A full set of basic and advanced troubleshooting capabilities including:

• Manual and automatic ranging
• Display Hold and Auto Hold
• Min/Max-Average recording
• Voltage measurements to 1000 V AC or DC
• Current measurements to 10 A AC/DC
• Resistance to 50 MΩ; capacitance to 10,000 μF, frequency to 100 kHz; temperature from -40 ℃ to 400 ℃

Insulation Resistance Testers

Perform tests, collect data wirelessly and from a safe distance

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
• Timer settings up to 99 minutes for timed tests
