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.<BR/><BR/>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.<BR/><BR/>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.

Casella Cel Sound Level Meter The Casella Cel CEL-240 is a 30dB to 130dB digital sound level meter. It is designed using the latest digital technology with 2-key operations. This device can easily specify the frequency wEighting and time wEighting. In addition to that, the meter allows simultaneous display of instantaneous and maximum sound pressure level measurement. It has a high-resolution LCD that displays a bar graph or graphical time-history of noise levels and offers an easy assessment of current noise environment. The CEL-240 automatically recognises the application of a calibrator and with a single keypress adjusts the calibration. AC output provided for DAT tape / PC wav file recording or headphone applications. This device comes with 3AA alkaline batteries, windshield, and a carry strap.
