Built on the standardised digital DX sensor platform, these portable air speed and flow meters with DX interface transfer measurement data and calibration values directly to the connected handheld meter. Hot-wire sensing technologies cover a wide velocity range, allowing you to measure air speed, volumetric flow rate, and temperature in ventilation ducts and HVAC systems. Swapping probes requires no recalibration, keeping your workflow uninterrupted and your results consistently accurate.
