For professionals in industrial maintenance, quality assurance, and R&D, few names carry as much weight as Fluke when it comes to precision measurement. While Fluke is famous for its handheld multimeters and thermal imagers, its Fluke DAQ (Data Acquisition) systems —specifically the Hydra Series (2638A, 2635A, 2645A)—are workhorses for long-term temperature, voltage, and resistance recording.
Fluke has shifted its focus to newer platforms (like or 2638A Link software) or discontinued active support for legacy DAQ 6.0. The software is roughly two decades old and was designed for Windows 95, NT, and 2000 .
