The Amprobe SM-20A Sound Meter has been designed to check compliance with safety regulations and perform acoustic analysis by safety engineers, health, industrial and safety offices as well as quality control. The SM-20A offers a PC interface.

They use two different weighting filters required by the IEC651 and ANSI S1.4 Type 2 for audio filtering. The A weighting is for general noise sound level and the C weighting is for measuring sound level of acoustic material control in various environments (ie 94 dB 1  kHz, etc).

Features :-

* Frequency & time weighting meet IEC 61672 class 2.
* A, C weighting, Max. hold, Data hold, fast/slow time weighting, AC/DC output.
* Range : 3 ranges, 30 to 130 dB.
* Size : 245 x 80 x 35 mm.

The Amprobe SM-10 Sound Level Meter is designed to meet the measurement requirements of Safety Engineers, Health, Industrial safety offices and Quality Control in various environments. It offers two types of measurements: A and C weighting. The A weighting is for general noise sound level and the C weighting is for measuring sound level of acoustic material control in various environments (ie 94dB 1 kHz etc...). The SM-10 conforms to the IEC651 Type 2, ANSI S1.4 Type 2, and JISC1502 requirements for Sound Level Meters. Which means the SM-10 uses two different weighting filters required by the IEC 651 and ANSI S1.4 Type 2: the A-Weighting and the C-Weighting audio filtering. 

The Fluke 945 Sound Level Meter has been designed to meet the measurement requirements of safety Engineers, Health, Industrial safety offices and quality control in a wide variety of industrial environments. It offers two types of measurements: A weighting and C weighting. The A weighting is for general noise sound level and the C weighting is for measuring sound level of acoustic material control in various environments. The Fluke 945 conforms to the IEC651 Type 2, ANSI S1.4 Type 2, and JISC1502 requirements for Sound Level Meters.
