Description

The HHSL402SD is a generalpurpose handheld instrument that measures the noise level of an environment or the sound level produced by a piece of machinery. Using an integrated 13 mm (0.5") condenser microphone, the meter can measure sound levels from 30 to 130 dB with a resolution of 0.1 dB and show the results on a front-panel liquid-crystal display. Several features and capabilities enhance the meter’s versatility. Among them are autoranging, the ability to hold readings and display maximum and minimum readings, and user-settable measurement parameters such as frequency weighting (using the “A” and “C” standards) and time weighting (fast or slow). Because it is microprocessor-based, the HHSL402SD can make full use of the portability, reliability and large storage capacities that SD memory cards offer.

Measurements can be made automatically at any sampling rate between one second and one hour. After timestamping and storing the measurements on an SD card plugged into the instrument, the user can remove the card and plug it into to a laptop or desktop computer either directly or via a USB card reader. The data points are stored on the card as files with the .xls extension, which can be opened by Microsoft’s Excel application. The HHSL402SD has a backlit 64 mm (2.5") diagonal display and is powered by six “AA” alkaline batteries or an optional 9V AC/DC adaptor.

Rated 4 out of 5 by from Works great I got somewhere between 40-50 hours of db logging before the batteries died. The instruction manual was good for telling you how to operate the device, however there's not a lot of detail about how to view the data once it's collected. Familiar with another Omega device I assumed that I was going to need the software. The software is definitely not needed unless you want to chart the data and view it in real time with your PC. To start logging simply turn on the device, use the manual to choose your device settings (the one thing that I felt the manual did really well was tell you how to set up the device) press record then press logger. It will start recording decibels into a "Text (Tab delimited)" file with 5 columns of data onto the supplied SD card. Place Date Time Value Unit The only value that probably needs a more detailed explanation is the Place value. The device creates a Text (Tab delimited) file and begins recording with the place value of 1, 2, 3,... all the way up to 30,000. Once it reaches this value it creates a new file and begins recording again starting at 1,2,3... You'll get 2 data files (or more depending on how long you record) and you can then combine all the data into one file and manipulate it with Excel. It worked great once I figured out how to use the device and to view the data. I hope this helped.
