Sound Level Meter Class 1 and Class 2

High SPL Sound Level Meter up to 184 dB

The 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 pressure 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 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 pressure microphone capsule thus extends the range of this already powerful instrument.

We’re excited to support your experience with the BSWA308/309 Sound Level Meter! 
To ensure smooth operation, we’ve compiled answers to common questions about measurement accuracy and calibration, along with a helpful tutorial video for your reference.
Frequently Asked Questions:
 
1. Measurement Accuracy Issue:
Seeing low results under low or high sound pressure?
 
Solution:
Regularly calibrate your device to maintain precision.
 
2. Calibration Value Issue:
Facing high or low calibration values or results?
 
Solution:
Ensure the sound level meter’s calibration setting matches the calibrator’s gear. For best results, perform a “Factory Reset” on new devices to guarantee optimal performance of both equipment and software.
