Equivalent Noise Level Measurement Noise Meter Data Logger / MI1SKG-403M

The noise meter MI1SKG-403M is a digital noise meter with a data logger function that can handle equivalent noise level measurements and regular noise measurements.

The MI1SKG-403M sound level meter is a digital sound level meter equipped with a data logger function that can handle equivalent noise level measurements and standard noise measurements. The equivalent noise level can be selected for intervals of 10 seconds, 1, 5, 10, 20, 30 minutes, and 1, 2, 4, 8, 16, and 24 hours. When the equivalent noise measurement starts, a timer activates, and upon completion, the equivalent level is displayed. With a data logger function that has a memory capacity of 64,000, it can record noise over long periods along with date and time. It complies with the sound level meter standard IEC61672-1 Class 2 (conforming to JIS C 1509-1: 2005 Class 2). It measures noise in an automatic range from 30 to 130 dB with high accuracy of ±1.4 dB. The noise during measurement is displayed in numerical values with a resolution of 0.1 dB and as a bar graph.
