Our Testing Experience

First Impressions

When I first got the Fluke 787B ProcessMeter, I was excited to see how it would handle my testing needs. Right out of the box, the size caught my attention—it’s compact but feels solid and well-built. I started by checking the 20 mA DC current source and loop calibrator functions. Setting it up was straightforward, and the display was clear. It felt like a professional tool that was easy to use even on my first try.

Daily Use

Using the 787B every day on the job made me appreciate its design more. It’s not too bulky, so carrying it around was comfortable. The true-RMS digital multimeter function was a lifesaver when I needed precise voltage and current readings up to 1000 volts. I liked that it met the IEC 1010 CAT III safety standards, which gave me peace of mind working in industrial environments. It became my go-to meter for checking loops and calibrating instruments without any hassle.

Key Features in Action

The 20 mA loop calibrator and current source were the standout features for me. They made simulating and testing current loops really easy and accurate. The true-RMS capability helped me get reliable readings even when the signals weren’t perfect sine waves. Plus, the meter’s precision and safety rating meant I could trust the measurements and focus on my work instead of worrying about the tool’s limits.

Long-Term Performance

After using the Fluke 787B for several weeks, I noticed it stayed reliable and consistent. The battery life was solid, and the device didn’t show any signs of wear despite daily use in tough conditions. It maintained its accuracy and the build quality felt durable. Overall, it proved to be a dependable tool that I would recommend to anyone needing a quality process meter for field work.

Best For	Process technicians and engineers needing a precise loop calibrator combined with a true-RMS multimeter.	Users seeking a reliable, high-quality protective carrying case for their Fluke process meters.	Electricians and technicians requiring a rugged, versatile multimeter for harsh environments and extended use.

In my opinion, the Fluke 787B ProcessMeter stands out because it combines a precision loop calibrator with a true-RMS digital multimeter that meets stringent safety standards, making it ideal for process calibration tasks. While the RLSOCO Hard Case offers excellent protection and portability, it is an accessory rather than a measuring tool. The Fluke 87V MAX excels as a rugged multimeter for harsh conditions but does not provide the loop calibration capabilities of the 787B. If you prioritize combined loop calibration and precise measurement in one device, the Fluke 787B is the better choice.
