Sper Scientific Mini Sound Meter: Pocket-Sized Power, Professional Precision
Meet the Sper Scientific Mini Sound Meter—a device that proves great things come in small packages. Despite being compact and light enough to slip into your shirt pocket, this meter is loaded with professional-grade features for comprehensive sound analysis.
Advanced Features, Simple Operation
Take control of your sound measurements with selectable fast or slow time weightings to capture either peak or average noise levels. Easily switch between A and C frequency weightings to measure sound as the human ear perceives it (dBA) or to capture low-frequency noise from machinery (dBC). The intuitive interface allows you to view min/max readings, hold a specific measurement, and see all your settings clearly on the large 1¼” backlit display, which ensures perfect visibility even in low-light conditions.
Unmatched Accuracy and Reliability
Engineered for precision, this meter offers an auto-ranging capability from 30 to 130 dB with a fine 0.1 dB resolution and a high accuracy of ±1.5 dB. Its stable and reliable readings make it an indispensable tool for a wide range of applications, including:
- Occupational Health & Safety (OSHA): Monitor workplace noise levels to ensure compliance and protect employee hearing.
- Environmental Noise: Assess noise pollution from traffic, construction, and residential areas.
- HVAC/R: Check the noise output of heating, ventilation, and air conditioning systems.
- Audio and Home Theater: Calibrate sound systems for optimal performance.
The meter is designed for convenience with an auto-power-off feature to conserve battery life. It arrives ready for immediate use, complete with a foam windscreen for accurate outdoor readings, a 9V battery, and detailed instructions.
For professionals requiring certified accuracy, an optional N.I.S.T. Traceable Certificate of Calibration is available. The unit can be easily recalibrated using the Acoustical Calibrator 850016.
