Professional Acoustic Monitoring Made Simple
Excessive noise is more than just a nuisance; it’s a health and compliance risk. The Smart Sensor AS804 is engineered to provide professional-standard accuracy for both indoor and outdoor environments. With its high-sensitivity condenser microphone, this device captures sound levels from whisper-quiet rooms to thunderous industrial machinery with an accuracy of +/- 1.5dB.
High-Precision Engineering for Reliable Data
Unlike smartphone apps that vary by hardware, the AS804 uses a dedicated A-weighting (dBA) frequency characteristic, which mimics the human ear's response to noise. This ensures your readings are relevant to safety standards and environmental regulations. The broad frequency response (31.5Hz to 8.5KHz) allows you to analyze a full spectrum of sounds, from low-frequency hums to high-pitched sirens.
Rugged, Portable, and Intuitive
Designed for field use, the AS804 fits comfortably in one hand. The integrated wind-resistant sponge ball ensures that wind interference doesn't skew your outdoor readings. The large 5-digit LCD screen features a bright green backlight, making it indispensable for late-night site inspections or darkened server rooms. With the Max/Min lock feature, you can easily capture peak noise levels without staring at the screen constantly.

FAQ Section
FAQ Section
Q: Does this meter measure in dBC or just dBA?
A: The AS804 is specifically designed for dBA (A-weighting), which is the standard used for environmental noise and human hearing protection regulations.
Q: Can I use this for outdoor traffic monitoring?
A: Yes! The included windscreen (black sponge) helps reduce wind noise interference, making it ideal for roadside or construction site checks.
Q: Does it come with a calibration certificate?
A: It is factory-calibrated for immediate use. For high-stakes industrial compliance, we recommend periodic checks with a standard acoustic calibrator.
