The Flus MT-911A tracks sound intensity from 35dB to 135dB with ±2.0dB precision. Under the hood, a thermal sensor captures ambient temperatures between -20°C and 70°C. It updates readings every 300ms to detect sudden noise spikes in high-traffic areas.
Key Features
- Dual Measurement: 35-135dB range paired with -20 to 70°C temperature sensing. Tracks acoustic and thermal data in one unit.
- LCD Backlight Display: 0.1dB resolution on a high-contrast screen with integrated lighting. Readings stay visible during local load shedding.
- MAX/MIN Data Hold: Captures and freezes the highest or lowest recorded values. Simplifies noise monitoring for industrial safety standards.
- A-Weighting Frequency: 31.5Hz to 8kHz range matches human hearing response curves. Detects harmful frequencies in loud work environments.
- Power Supply: Three 1.5V AAA batteries power the internal circuitry. Standard cells provide long operation times between replacements.
