Mount these monitors to your wall to view the sound level of your plant from 100 feet away. This helps you continuously keep an eye on the amount of noise in your work environment to make sure it’s safe. When the sound level exceeds your programmed threshold, the numbers on these monitors will turn from green to red. The A weighting is similar to the response of the human ear and is used by OSHA.

Attach them with the mounting holes on the back. The included cord lets you transmit data to your computer.

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 to calibrate the monitor on a regular basis 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.

Clip these monitors on to measure your noise exposure. Also known as personal noise dosimeters, they continuously measure ambient sound levels, intensity, and duration. You’ll often see them used in factories, airports, and construction sites to help comply with OSHA regulations for noise exposure. These monitors give noise dose as a percentage of the maximum safe daily limit and alert you when levels are outside your set threshold. You can choose from preprogrammed sound level tests or program your own. Set the monitor to record automatically or program it to record samples at timed intervals.

An electronic filter adjusts the way these testers measure sound, so you can choose the frequency weighting you need. The A weighting mimics the human ear’s response to sound. It is used by OSHA to measure the risk of potential hearing damage. The C weighting measures low-frequency sounds, so it’s often used to measure the sound level of machinery. The Z weighting gives you a flat frequency response and represents the actual noise without any adjustments.

Transmit readings to your PC with the included cord. The included software lets you review stored sound measurements and analyze measurements in real time.

Use a calibrator before and after each use to keep monitors accurate and maintain compliance with ANSI standards.
