High SPL Sound Level Meter - Class 1 with recording function
The BSWA 308 Class 1 Sound Level Meter is an instrument for measuring sound pressure levels in decibels. It follows the International Organization for Standardization (ISO) standards for accuracy and precision. Its high accuracy and low uncertainty make it ideal for measuring loud phenomena such as gunshot sounds.
The optional high sound level microphone capsule extends the sound level range of the meter. It can measure loud sounds of up to 184 decibels without saturation or distortion. This capsule is especially useful for measuring sounds in military, engineering, and entertainment applications.
The unit is equipped with a large digital display that shows real-time decibel readings. It also has a data logging function that records sound levels over time. The unit is powered by rechargeable batteries and is lightweight and portable, making it easy to use.
Overall, the BSWA 308-HSPL Class 1 Sound Level Meter provides accurate and reliable sound level measurements, especially in high sound level environments. The optional MK 301 E or MK 342 E high sound level microphone capsule thus extends the range of this already powerful instrument.
