REED Instruments R8050 Sound Level Meter, Type 2, 30-100 and 60-130dB, -1.4 dB Accuracy with NIST Calibration Certificate

Works really well.

All as expected

Excellent for measurinh noise levels for fans in electroic equipment and air filters.

I purchased this product to adjust the sound levels from each of the speakers in my 7.1 surround sound system. The meter is very well made, easy to use, and gave reproducible results when measuring the output of all of my speakers. I liked the fact that the meter could be used in both A and C modes as the latter is required when measuring the output of speakers in a surround system. I had previously tried a less expensive sound level meter that had arrived dead on arrival. The Reed R8050 worked immediately upon removal from the box and insertion of batteries. This is clearly a case of you get wha you pay for. Highly recommended.

Muy responsivo. Calidad de construcción sólida. Producto de uso profesional. Sin embargo, hay aplicaciones de iPhone que, una vez calibradas, entregan resultados idénticos y tan repetibles como este equipo.

Bought this for work for testing ...works very well and accurate

I've owned this for several years now and it has always worked well. Mostly I've measured the db's of air conditioners and noisy neighbors to compare with the rules and regulations that apply, but I also measured the sound level of a PA/music system to show that the volume was too high to have a conversation over. Search for those levels online.
