Whether used for industrial monitoring, acoustic analysis, laboratory testing, or everyday noise assessment, the FNIRSI FDM02 offers the perfect balance of precision, performance, and portability — making it a must-have tool for anyone who values sound quality, safety, and compliance.
Professional-Grade Accuracy and Wide Measurement Range
The Zigmotech FNIRSI FDM02 features a comprehensive measurement range of 30dB to 130dB, making it suitable for capturing both subtle background noise and high-intensity sound levels with equal precision. Its high-sensitivity condenser microphone ensures a fast, stable response to changes in sound pressure, providing consistently accurate readings even in fluctuating environments.
Whether you’re monitoring industrial machinery, testing classroom acoustics, evaluating noise pollution, or tuning an audio system, the FDM02 gives you precise and dependable results every time.
AC Weighting for Realistic Sound Evaluation
To ensure that readings reflect how sound is perceived by the human ear, the FDM02 incorporates an AC weighting filter. This function simulates the natural frequency sensitivity of human hearing, allowing the device to deliver results that align with real-world acoustic experiences.
By emphasizing frequencies between 1kHz and 6kHz—where human ears are most sensitive—AC weighting provides realistic, reliable noise assessments that are essential for environmental studies, occupational noise evaluations, and compliance testing.
Advanced Digital Signal Processing (DSP) Technology
At the heart of the Zigmotech FNIRSI FDM02 lies its intelligent digital signal processor, designed to enhance measurement accuracy and data stability. The DSP engine filters unwanted noise fluctuations, compensates for environmental variations, and ensures smooth real-time updates on the display.
This intelligent system guarantees minimal measurement error, making the FDM02 a dependable choice for professional noise analysis in laboratories, factories, or outdoor environments where conditions constantly change.
Vibrant Full-Color LCD Display
The large full-color LCD screen is a key highlight of the FNIRSI FDM02, offering crisp, bright visuals for easy data interpretation. The screen clearly shows the current sound level in decibels, along with indicators for max/min readings, data hold, and battery status.
Its backlit display ensures excellent visibility in both daylight and low-light conditions, making the device suitable for indoor or field use at any time of day. The color-coded interface enhances readability, allowing users to instantly assess sound intensity levels with clarity and confidence.
Compact, Ergonomic, and Portable Design
The Zigmotech FNIRSI FDM02 is designed with portability and user comfort in mind. Its lightweight, ergonomic design allows for one-handed operation, and the durable ABS outer casing provides protection from wear and impact during everyday use.
Compact yet powerful, this noise meter is easy to carry in a toolkit, lab bag, or field case, ensuring that accurate sound measurement is always within reach — wherever you work.
User-Friendly Features for Flexible Operation
Zigmotech ensures every feature serves a practical purpose. The FNIRSI FDM02 includes multiple user-friendly functions to enhance usability and accuracy:
-
Max/Min Recording: Automatically captures and stores the highest and lowest noise levels measured during a test session.
-
Data Hold Function: Freezes the current reading for easy recording or analysis.
-
Backlight Control: Adjustable backlight for clear visibility in all lighting conditions.
-
Auto Power-Off: Conserves battery life by shutting down automatically after periods of inactivity.
These intelligent features make the FDM02 versatile and easy to use, even for extended monitoring sessions or mobile fieldwork.
Exceptional Accuracy and Fast Response
The Zigmotech FNIRSI FDM02 offers fast response times and high accuracy, typically within ±1.5 dB, allowing users to trust every reading they take. The integrated high-sensitivity condenser microphone responds rapidly to sound changes, ensuring smooth, real-time updates and reliable measurement of transient or fluctuating noise sources.
From steady industrial background hums to sudden loud impulses, this sound meter captures every detail with unmatched consistency.
Durability and Long Battery Life
Built for both indoor and outdoor use, the FNIRSI FDM02 is engineered from high-quality ABS materials that resist wear and environmental stress. It runs efficiently on standard batteries, offering long operational time for extended measurement sessions.
Its low power consumption and intelligent energy management make it suitable for continuous field work, classroom demonstrations, or multi-location surveys without frequent recharging or battery replacement.
