Product Details

Castle GA216B Sonus Class 2 Sound Pressure Level Meter (non data logging version)

Castle GA216B is designed for general survey health & safety and engineering applications by industrial safety officers, occupational nurses, fire alarm installation & test engineers and industrial engineers. It gives clear results which meet the requirements of international standards. GA216B is a Sonus range entry-level Type 2 sound meter fully compliant with IEC 61672-1:2002. The difference between Type 1 and Type 2 is in the tolerance, for example: at reference frequency 1kHz, tolerance is ±1.1dB (Type 1) and ±1.4dB (Type 2); at 20Hz, tolerance is ±2.5dB (Class 1) and ±3.5dB (Class 2). Compliance with IEC 61672-1:2002 Class 2 and IEC 60651:1979 Type 2 is necessary for carrying out most noise assessment tasks in industry.
