Casella Cel CEL-120/2 音量校準器 114dB 1kHz CEL-120/2 CEL-120/2

Feature

• IEC 6094: 2003 and ANSI S1.40: 2006. CEL-120 Class 2 Acoustic Calibrator. The CEL-120/2 is a Class 2 accuracy Acoustic Calibrator and is the smallest of its type in the world; with a rugged, over-moulded design for use in field environments. The field calibration of sound level meters is an essential procedure when carrying out any type of noise survey both before and after each measurement sequence. This ensures that sound level measuring instruments are providing consistently accurate readings necessary for monitoring to ensure compliance with workplace and environmental noise regulations. The CEL-120/2 is therefore designed and manufactured to comply with the requirements of IEC 60942: 2003 and ANSI S1.40: 2006. These standards stipulate accurate calibration over a wide range of temperature, humidity and pressure conditions, typical of field work, ensuring accurate calibration in all conditions.
