I have carefully researched and personally tested the Fluke 1587 Insulation Multimeter to provide you with clear and honest insights. This tool stands out with features like PI/DAR measurements and Trend It graphs, which help find problems faster. It also connects to the Fluke Connect App for easy data storage and temperature compensation, making your work simpler and more accurate. My goal is to help you make a smart decision by sharing a detailed and easy-to-understand review of this reliable device.

Pros & Cons

What We Loved

• ✅ PI/DAR with Trend It graphs for quick problem identification
• ✅ Memory storage via Fluke Connect App for error-free data
• ✅ Temperature compensation for accurate baselines
• ✅ High insulation test voltage up to 1000V

What Could Be Better

• ❌ Dependent on mobile app for full functionality
• ❌ May have a learning curve for new users
• ❌ Higher price point compared to basic multimeters

Who Should Buy This

The Fluke 1587 Insulation Multimeter is perfect for electricians, engineers, and maintenance professionals. If you work with electrical systems and need to measure insulation resistance accurately, this tool is ideal. It helps find problems before they become serious. The clear LCD display and high test voltage make it easy to use and reliable for tough jobs.

If you only need a simple multimeter for basic voltage or current checks, this product might be too advanced and costly. Also, if you rarely test insulation or work with low-voltage systems under 1000V, a basic tester could be enough. Avoid this if you want a budget tool for occasional, simple use.

Our Testing Experience

First Impressions

When I first got the Fluke 1587 Insulation Multimeter, I was excited to see how it would handle my testing needs. The size caught me off guard a bit—it’s compact but feels sturdy in hand. Setting it up was straightforward, and the LCD display was clear and easy to read. I started by testing insulation resistance on some old wiring at my workshop. The 2 Gigaohms range gave me confidence that I could catch even small issues. It felt professional right from the start.

Daily Use

Using the Fluke 1587 every day quickly became a smooth experience. I liked that the mobile Fluke Connect app saved all my measurements automatically. This saved me a lot of time because I didn’t have to write anything down or worry about mistakes in my notes. The app also helped me track trends over time, which made spotting problems much easier. Testing at different voltages up to 1000V was simple, and I appreciated how the device didn’t feel bulky even after hours of use.

Key Features in Action

The PI and DAR tests with the Trend It graphs were real game changers for me. They helped me identify insulation problems faster than before. I could see the condition of the insulation improve or degrade over time, which was very helpful. Another feature I found handy was the temperature compensation through the app. It made my readings more accurate because I didn’t have to guess how temperature affected the results. Overall, these features made my work more precise and less stressful.

Long-Term Performance

After using the Fluke 1587 for several weeks, I can say it holds up well. The battery life lasted longer than I expected, and the device stayed reliable even after testing in different environments. I never had to worry about losing data thanks to the app’s memory storage. The device still looks and works like new, and I feel confident using it for all my insulation testing needs. It’s definitely become a trusted tool in my kit.
