FABISENSE HT622B Professional Sound Level Meter 30-130dB A/C-Weighted Decibel Noise Logger with USB Interface & Analog Bargraph

FABISENSE HT622B Flagship A/C-Weighted Sound Level Meter with USB Data Logging

The FABISENSE HT622B is a professional-grade sound pressure level (SPL) meter built for comprehensive industrial acoustic analysis and sound quality engineering. Upgraded with A/C dual frequency weighting and a built-in USB interface, this flagship meter allows you to not only measure human-perceived sound but also evaluate mechanical noise and export raw data to your computer for deep analytical reporting.

Key Features:

• Professional A/C Dual Weighting:

  • A-Weighting: Measures standard environmental noise as perceived by the human ear.

  • C-Weighting: Measures low-frequency mechanical sound profiles, making it perfect for auditing factory engines, subwoofers, HVAC machinery, and industrial plants.

• USB Connectivity & Data Export: Seamlessly connects to your PC or laptop via USB, turning the unit into an active sound data logger for long-term acoustic mapping and compliance reports.

• Dynamic Range Sub-Filtering: Allows you to isolate measurements across multiple specialized ranges (e.g., 30-80dB, 80-130dB) with smart automatic or manual over/under range protection.

• Dual Capture Speeds: Switch easily between FAST (125ms) modes for sudden acoustic blasts and SLOW (1s) parameters for stable, ongoing sound system calibrations.

• Premium Display Architecture: Combines a high-definition backlit screen, a smooth dynamic electronic bargraph, Max/Min lock functions, and low battery notifications for industrial field deployment.
