The HHSL-101 is a low-cost, compact, battery powered sound level meter capable of unattended logging (recording) of the decibel level of an environment for days, weeks or months. Data logging can be started or stopped by pushing a button on the unit, eliminating the need to bring a laptop to the job site.
The HHSL-101 is ideal for monitoring environmental and industrial noise as well as for measuring decibel levels during acoustical design and sound system setups
After a data log has been captured and stored, it can be uploaded as a .txt file to any PC running Windows® XP, Windows® 7 or Windows® 8 operating system after plugging the HHSL-101 into a computer’s USB port. The HHSL-101 has internal flash memory that is large enough to store up to 32,000 data points. Software is included with the product—which is slightly larger than a thumb drive—that can display a data log file as a table or graph and/or export it to Microsoft Excel®. Exporting to Excel is recommended for sophisticated trending and analysis of sound level data and easy detection of unexpected excursions.
