BSWA308 Class 1 Sound Level Meter

This is the BSWA308 Class 1 sound level meter which complies with IEC 61672-1:2013, ANSI S1.4-1983 and ANSI S1.43-1997. The linearity range is 20dBA~134dBA and it has a single range to cover 123dB dynamic range. They have a frequency weighting A/B/C/Z and a time weighting of fast/slow/impulse. There is a 3 profile calculation in parallel with different frequency/time weighting and 14 custom define measurement. This meters come as standard with 1/1 Octaves, however, you have the option of 1/3 Octaves. It will calculate SPL, LEQ, Max, Min, Peak, SD, SEL and E and there is LN statistics and time-domain curve display.

The BSWA308 has user define integral period measurement and high speed ARM with FPU (Float Point Unit) to achieve wide dynamic range and low noise floor as well as 4G MicroSD card (TF card) mass storage. There is a RS-232 remote control port and a mini thermal printer for measurement data print.

Please Note: The Peak C Range of this instrument is 45dB(A)~137dB(A)
