Wherever you need to monitor sound levels, the Protmex sound meter will do the job.

The meter utilizes a 1/2-inch electric condenser microphone to monitor sound levels from 30 to 130 decibels at an accuracy of +/-1.5 dB with a 0.1 dB resolution.

A windscreen is included to prevent distortion in the readings.

The large LCD display gives readings in large, clear numbers.

At the same time, it shows the sound level readings using a fast-responding analog bar graph with a 50-decibel range that updates every 40 milliseconds for viewing varying trends.

The unit has AC analog output and records max/min values over time.

The Protmex sound meter weighs less than 6.7 ounces, and is designed to fit comfortably in the palm of your hand.

Choose between either A or C weighting, auto or manual ranging.

Other useful features include auto power-off, max hold functions, and fast/slow response time.

Record sound values over time to track sound changes.
