Etymotic Research launches the ER-200 portable noise dosimeter. The portable screening device provides a good estimate of noise dose and alerts the user to the risk of over exposure.
The ER-200 offers two modes of operation: Normal Mode measures and displays noise dose continuously for up to 16 hours, and Quick Check measures noise for two minutes, then calculates and displays the estimated dose per hour. It has LEDs to show you the noise level and it uses three AAA batteries.
The Etymotic ER-200 is priced at $99.
