Sound Level Testers
Take readings of ambient sound levels. These portable testers give you spot readings, so you can monitor workplace machinery and vehicles, comply with safety regulations, and adhere to noise ordinances.
Testers have a selectable frequency weighting—an electronic filter that adjusts the way the tester measures sound. The A weighting is similar to the response of the human ear and is used by OSHA. The C weighting is suitable for measuring the sound level of machinery.
Testers with NIST certification include a calibration certificate traceable to NIST.
Testers with a backlit display can be read in dim areas.
Testers with an SD card store timestamped readings in Excel format for easy data logging and PC transfer. The SD card stores up to 20 million readings.
Use the calibrator (sold separately) to calibrate the tester before each use and verify that it is working properly.

Make sure your sound level monitor or tester provides reliable readings. These calibrators have a small speaker that generates sound at precise levels, so your monitor can be accurately calibrated before each use.

Sound Level Monitors
Continuously measure ambient sound levels. The display alerts you when levels either exceed or fall below your programmed thresholds. When operating the monitor with the included 120V AC adapter, four warning lights will also flash when a threshold is reached. Monitors have a microphone that rotates 180°. They can be surface mounted or propped up using the attached folding stand. These monitors cannot be sold to Canada due to import regulations.
You can select the frequency weighting—an electronic filter that adjusts the way the monitor measures sound. The A weighting is similar to the response of the human ear and is used by OSHA. The C weighting is suitable for measuring the sound level of machinery.
Use a calibrator (sold separately) to calibrate the monitor on a regular basis and verify that it is working properly.
