393-1100 Earfit Dual Ear Validation System

Real fit = real results
The E-A-Rfit™ subject fits their own protector, the technician connects the microphone to the hearing protector, leaving the other microphone exposed so that noise levels are measured inside and outside the ear.

Personal Attenuation Rating (PAR) for each worker in minutes
It only takes 8 seconds to obtain data at seven standard (125Hz to 8000Hz) frequencies. You'll know exactly what level of protection each worker receives from each tested protector. No guesswork.

Data is documented for future use. Each worker's PAR results can be automatically documented and stored by the technician. This information is valuable for comparison during subsequent tests.
