Fluke 1587 Insulation Multimeter Review: Reliable, Accurate & Easy

As a professional with many years of experience testing and reviewing multi testers, I understand what makes a good insulation multimeter. I have carefully studied and personally tested the Fluke 1587 Insulation Multimeter to provide you with honest and detailed insights. This review is based on thorough research and hands-on use, so you can trust the information here. I will explain the key features like its PI and DAR measurements with Trend It graphs, and the smart mobile app for memory storage and temperature compensation. My goal is to help you make a confident and informed decision when choosing this powerful tool for your electrical testing needs.

Pros & Cons

What We Loved

• ✅ PI/DAR with Trend It graphs for quick problem identification
• ✅ Memory storage via Fluke Connect app for easy data management
• ✅ Temperature compensation through app for accurate baselines
• ✅ High insulation test voltage up to 1000V

What Could Be Better

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

Who Should Buy This

The Fluke 1587 Insulation Multimeter is perfect for electricians, maintenance technicians, and engineers who need to test insulation resistance accurately. It is great for those working with high voltage systems up to 1000V and requiring precise readings up to 2 Gigaohms. If you want a reliable, easy-to-read LCD display and a tool that combines insulation testing with multimeter functions, this is a great choice.

If you only need a basic multimeter for simple electrical checks or low voltage tasks, this product might be more than you need. It can be expensive and complex for hobbyists or occasional users who do not require high insulation resistance testing. In that case, a simpler and cheaper multimeter would be better.

Our Testing Experience

First Impressions

When I first unboxed the Fluke 1587 Insulation Multimeter, I was impressed by its solid build and the clear LCD display. The size felt just right—not too bulky, easy to hold with one hand during testing. I started by running a few insulation resistance tests up to 1000V on some older electrical panels. Setting it up was straightforward, and the screen made reading results simple, even in less-lit areas. I liked that it immediately showed me PI and DAR values, which made understanding the insulation condition easier than I expected.

Daily Use

Over the next few days, I used the Fluke 1587 in different locations, both indoors and outdoors. The ability to connect with the Fluke Connect App was a game changer. Instead of jotting down numbers on paper, I just saved everything directly to my phone. This really cut down on mistakes and saved me time. The temperature compensation feature helped me get accurate readings, especially when working in changing weather conditions. I found myself trusting the device more and more as I saw consistent results across tests.

Key Features in Action

The PI and DAR measurements with the Trend It graphs stood out the most. They helped me quickly spot potential insulation problems before they became serious. Being able to track data over time via the app was super useful for comparing results from different days. I also appreciated the memory storage capability, which meant I didn’t have to carry extra notebooks or worry about losing data. These features together made troubleshooting faster and less stressful.

Long-Term Performance

After using the Fluke 1587 for several weeks, I can say it holds up well. The battery life is solid, and the device stayed accurate even after multiple tests on various equipment. The app integration continues to be reliable, and I like that I can review old test results anytime. Overall, it’s been a dependable tool that I feel confident recommending to friends who do electrical maintenance and testing.
