Dr.meter
Comes with compact and lightweight design, the Dr.Meter MS10 sound level meter is designed to fit comfortable in your palm. It's perfect for measuring noise levels in factories, offices, theaters and audio systems to give you accurate readings in a greater range than similar products in the market!
It utilizes a 1/2 inch electric condenser microphone to monitor sound levels from 30 to 130 decibels at an accuracy of +/-1.5dB with 0.1dBA resolution while reducing the effects of wind noise to produce more accurate readings. The MAX/MIN button will hold the highest/lowest reading until a much higher/lower reading is picked up. Together with a 9V battery, it can provide you about 50 hours of use. It will automatically power off after no operation for approximately 15minutes
