All-in-One Environmental Monitor – Features a large LED screen showing real-time decibel levels (30-130dB), temperature (°C/°F), humidity, time (24H), calendar (DD/MM/YYYY), and intuitive smiley alerts. The dynamic decibel bar graph and color-coded temperature indicators provide instant visual feedback.
Stay Informed at a Glance – The tricolor smiley faces change based on temperature ranges (too hot/cold/ideal), while the decibel bar flashes when noise exceeds safe levels. No need to interpret numbers—just check the symbols for quick warnings!
Professional-Grade Precision – Measures 30-130dBA with ±1.5dB accuracy and 0.1dB resolution, covering frequencies from 50Hz to 8.5kHz. The 1.5x/s sampling rate ensures fast, reliable readings, while the extra-large LED display guarantees clear visibility even from a distance.
Monitor Everything at Once – Tracks noise levels, temperature (14°F ~ 122°F), humidity (20-85%), time, and date simultaneously. Perfect for ensuring optimal conditions in classrooms, offices, factories, or homes—no more guessing!
Flexible Installation Options – Includes a sturdy wall-mount bracket for permanent placement or stands freely on desks. The A-weighted measurement mimics human hearing, making it ideal for noise compliance checks, workplace safety, and home comfort monitoring.
