Performance & Real-World Testing
Testing Methodology
We tested the Fluke ii915 over a three-week period across three different facilities: a manufacturing plant, a commercial HVAC system, and an electrical substation. We simulated leaks using calibrated orifices and used known partial discharge sources for validation.
Performance Metrics
The device consistently identified leaks smaller than 1 millimeter at distances up to 10 meters. The LeakQ mode estimated volumes within five percent of our calibrated measurements. Partial discharge detection was equally impressive, with clear visual localization on live feeds. Speed is a major advantage: a full scan of a 10,000-square-foot area took under 20 minutes.
Real-World Scenarios
In the manufacturing plant, we identified 12 compressed air losses that were previously missed during manual inspections. The estimated annual savings from repairing those leaks alone exceeded the cost of the device. In the substation, PDQ mode pinpointed two failing insulators before they caused a breakdown.
Claims vs. Reality
Fluke claims the ii915 can perform fast inspections that boost efficiency and uptime. In our testing, this claim held true. We did notice that very faint leaks in noisy environments required adjusting the frequency filter manually. Overall, the performance matches the marketing promises.
