Description
The Fluke 923 and Fluke 925 represent the industry standard for precision HVAC diagnostics, environmental monitoring, and ventilation system balancing. Engineered to deliver high-accuracy velocity, volume flow, and temperature readings, these instruments ensure compliance with international building performance and occupational safety standards. The Fluke 923 utilizes hot-wire technology for high-sensitivity measurements in confined ductwork, while the Fluke 925 employs a robust mechanical vane for high-volume laminar flow assessments at diffusers and grilles.

INDUSTRIAL APPLICATION SCENARIO
In pharmaceutical cleanroom validation and complex HVAC commissioning, precise laminar flow control is critical to prevent cross-contamination. The Fluke 923 solves the challenge of measuring low-velocity air currents inside narrow duct geometries where standard vane sensors cannot fit, utilizing its telescopic hot-wire probe. Conversely, the Fluke 925 is deployed at the supply and return grilles to measure total volumetric flow rates, ensuring the HVAC system meets the specified air exchange rates.
