FABISENSE HT622A Digital Sound Level Meter 30-130dB A-Weighted Decibel Noise Tester with Analog Bargraph, Max/Min & Backlight Screen

FABISENSE HT622A Digital Sound Level Meter – Precise Noise Monitoring

The FABISENSE HT622A is a highly reliable, compact digital sound level meter engineered to measure environmental noise with pinpoint accuracy. Featuring an advanced polarized capacitance microphone and a measuring range of 30 to 130 dBA, it is the perfect tool for monitoring noise levels in classrooms, offices, residential areas, theaters, and green spaces.

Key Features:

• Human-Ear Optimized (A-Weighting): Utilizes standard A-weighting properties to simulate the frequency response of human ear perception, making it ideal for environmental, health, and safety noise inspections.

• Real-Time Analog Bargraph: Equipped with a fast-acting visual analog bargraph on a large LCD screen to track sound fluctuations and trends instantly.

• Fast/Slow Time Properties: Offers adjustable time response settings—choose FAST (125ms) for fluctuating impact noise or SLOW (1 second) for steady, continuous background noise levels.

• Under/Over Dynamic Tracking: Smart built-in alarms flash "UNDER" or "OVER" indicators when the noise level moves outside your manually set decibel sub-ranges.

• User-Centric Functions: Supports Max/Min hold to lock peak decibel readings, standard data hold, auto power-off to preserve battery life, and a bright backlight for dark workspaces.
