E·A·R and Peltor have developed a simple sound level meter that complements the Optime Alert System by establishing which color code you need to follow.

You simply deploy the meter at the employees work station let it sit until the display has stablized, this then indicates the average noise level in that area and the type of protection required.

The display indicates the period of time the unit has been active in 1 hour increments up to a maximum of an 8 hour working day.

The sound check meter must be restarted between measurements.  The meter is accurate to ±1dB.
