HT622A Portable Mini Digital Sound Level Meter 30-130 dBA — Decibel Noise Monitor

The HT622A digital sound level meter (30-130 dBA) is designed for measuring noise from audio equipment and ambient sound in both professional and everyday settings. Typical applications include factories, workshops, schools, residences, office areas, traffic roads, audio setups, office buildings, restaurants, classrooms, and libraries. Built with multiple composite processes, the unit features a non-slip surface, drop-proof construction, and protection against dust and water. It uses a miniature condenser microphone sensor with a protective design to help the sound head survive accidental drops while maintaining normal operation. The meter delivers precise measurements and displays an over-range warning when levels exceed the instrument’s limits.
