About Hearing Protection
Earmuffs and earplugs are rated by the Noise Reduction Rating (NRR) guidelines, which are enforced by OSHA.

Sound Level Testers
Take readings of ambient sound levels. 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.
Use the calibrator (sold separately) to calibrate the tester before each use and verify that it is working properly.
Testers that cannot be sold to Canada are restricted by import regulations.

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 the calibrator (sold separately) to calibrate the monitor on a regular basis and verify that it is working properly. Remote microphone cable (sold separately) allows you to use the monitor’s microphone up to 15 ft. from the display.

Radiation Detectors
Detect alpha, beta, gamma, and X-ray radiation. A flashing red light with audio beep indicates the presence of radiation. This unit has a scale to show radiation detected in the air.

Digital Radiation Detectors
Detects lower levels of radiation than our standard detector. Measurements are displayed on an easy-to-read LCD. The unit has a protective rubber casing. A flashing red light with audio beep indicates the presence of alpha, beta, gamma, and X-ray radiation.
Use this detector alone to measure radiation in the air, or use it with the optional wipe test plate and sample collection wipes (sold separately) to measure radiation on surfaces. For surface testing, use a wipe on a wet or dry surface, place the wipe in the wipe test plate, and slide the plate onto the detector.
Personal Radiation Dose Meters
Track the accumulated X-ray and gamma ray radiation you’ve been exposed to. Attach these dose meters to your pocket or nearby objects with their sturdy metal clip. Use the charger (sold separately) to reset them to zero.

Hearing Protection Fit Testing Systems
In a matter of minutes, confirm your earplugs deliver the right level of hearing protection. These kits help you meet OSHA standards for protection from excessive noise. Conduct the test onsite—everything you need, including a tablet with software already installed, is included. To use this kit, you will undergo a hearing test with and without your earplugs to determine the lowest volume you can hear. The system then calculates the difference between the scores and produces a personal attenuation rating (PAR).
Once the test is complete, you’ll receive a full report to help you choose the best earplugs. The results automatically upload to cloud storage and can be accessed on multiple devices.
