MRM-308 Sound Level Meter

MRM-310 Sound Level Meter (30 to 130) dB

The MRM-310 Digital Sound Level Meter is perfect when you need simple noise information. The meter is capable of measuring the maximum sound level (LMax) and the sound pressure level (SPL). It is used for simple sound measuring applications, such as alarm testing, spot checks, and very basic occupational noise checks. It provides an entry level for noise measurement across multiple sectors, and meets current international standards for noise measurement instrumentation.

The sound pressure level (SPL) and maximum sound level (LMax) readings can help you determine how loud something/somewhere is without over-complicating the data with other acoustic information. It can also measure different frequency weightings, which provides more detailed and accurate data than many other basic sound level meters available on the market.

The MRM-310 displays the SPL and LMax data, and comes with the ability to set your own noise level alert. Simply choose a decibel level, and when the meter records a noise level that meets or exceeds your pre-set value, an indicator will appear on the screen. This is incredibly useful when you need to know quickly and easily whether or not something is louder than a prescribed value. It can display the Leq for one measurement, using the start/stop button on the instrument. It can also send results directly to a portable printer, which is sold separately

Made in the UK and comes with a one-year manufacturer’s warranty.
