Advantages

The Habotest HT622B offers straightforward and reliable sound level measurement with selectable A and C weighting, enabling users to approximate human ear sensitivity or capture low-frequency noise. Its digital readout provides clear numerical results, while the USB interface facilitates data export and basic logging for documentation. Compact construction and handheld operation simplify use in various field environments.

Suitable for

• On-site environmental noise surveys
• Workplace noise exposure assessments
• Acoustic troubleshooting and verification
• Routine maintenance checks by technicians and engineers

Key specifications

• Measurement weightings: A and C selectable
• Digital display for instantaneous sound level readings
• USB interface for data transfer and logging
• Handheld portable form factor suitable for field use

How to use

Power on the Habotest HT622B and select the desired weighting (A or C) according to the measurement objective. Hold the meter at the measurement position, away from reflective surfaces, and allow the display to stabilise to obtain a representative reading. Use the USB interface to connect the device to a computer when data export or logged records are required. Follow any applicable standards or workplace procedures for measurement location, duration and reporting.

Recommendations

For repeatable results, perform measurements at consistent positions and heights, avoid placing the microphone near obstacles, and select A-weighting for general occupational noise assessments or C-weighting when low-frequency noise is significant. Use the USB connection to archive readings and to support compliance documentation.
