ST-11D

ST-11D

The ST-11D sound level meters are fully compliant with the latest IEC 61672:2013 Class 1 standard. 

Integrated smart integration algorithms and a wide measurement range of 27-140 dB, suitable for even the most demanding industrial uses.

They measure and display the Leq value. They show the Equivalent Continuous Sound Level and sound exposure based on the selected time period, ideal for professional noise measurements, as required by occupational noise control regulations or OSHA occupational noise standards. They protect and ensure employee hearing and workplace safety at the forefront.
