E.A.R Optime Alert System - Sound Check Meter
3M has a simple sound level indicator for its E.A.R and Peltor products that compliments the Optime Alert System by establishing which colour code you need to follow.
- You simply deploy the meter at the employees work station let it sit until the display has stabilised, this then indicates the average noise level in that area and the type of protection suggested.
- 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.
