Our Testing Experience

First Impressions

When I first received the Fluke 28 II Rugged Digital Multimeter, I was impressed by its solid build and compact size. At just 3.0 x 6.0 x 12.0 inches, it felt easy to handle but still sturdy enough for tough jobs. Before starting, I noticed it came with a NIST-traceable calibration certificate, which gave me confidence that the readings would be accurate right from the start. I immediately powered it on and tested a few simple circuits to get a feel for the high-resolution 20,000 count display. The screen was bright and clear, making it easy to read even in low light.

Daily Use

Using the Fluke 28 II daily on my workbench and in the field was a smooth experience. Its rugged design lived up to the name — I accidentally dropped it a couple of times, but it kept working without any issues. The large, easy-to-use buttons made switching between different measurement modes quick and hassle-free. Whether I was measuring voltage, resistance, or continuity, the readings were steady and reliable. I especially liked that it was ready to use immediately, thanks to the pre-shipment calibration, so I didn’t waste any time setting it up.

Key Features in Action

The high-resolution 20,000 count display was a game changer. It allowed me to catch small fluctuations in readings that other meters might miss. This was really helpful when diagnosing tricky electrical problems. The fact that the unit was calibrated with a NIST-traceable certificate gave me peace of mind that the measurements met strict quality standards. Another feature I appreciated was the rugged case — it protected the meter well during outdoor and industrial use, making it feel like a tool that would last a long time.

Long-Term Performance

After using the Fluke 28 II for several weeks, I can say it performed consistently without any drop in accuracy or reliability. The battery life was solid, and the meter always powered on quickly. Even after rough handling and exposure to different environments, it stayed in great shape. This multimeter felt like a trusted companion for all my electrical testing needs, and I believe it will continue to perform well for years to come.
