Casella CEL Introduces New Acoustic Calibrator

AMHERST, NH, November 29, 2011 -- Casella CEL Inc., a business unit of IDEAL INDUSTRIES, Inc., has introduced the world's smallest acoustic calibrator. Measuring just 75.5mm x 54.0mm x 37.0mm, the new CEL-120 helps users achieve highly accurate calibration of sound level meters in the field.

Calibration is an essential procedure when conducting any type of noise survey both before and after each measurement sequence. The process ensures that instruments are providing consistently precise readings necessary for monitoring to comply with workplace and environmental noise regulations.

Fully compliant with IEC 60942:2003 and ANSI S1.40:2006 standards, the new CEL-120 incorporates the latest digital technology for exceptionally stable acoustic performance, as well as dual calibration level (Class 1 version) of 94dB and 114dB at 1kHz. Designed for real-world operating conditions, the CEL-120 has a rugged, over-molded design to withstand field environments.

For added ease-of-use the CEL-120 features a simple keypad specially designed for intuitive control, permitting calibration level changes as required. When used with instruments such as Casella's well proven CEL-600 series of sound level meters, calibration routines start automatically as soon as a tone is detected.

A MEMS (Micro Electrical-Mechanical System) microphone and a digital feedback loop maintain the acoustic pressure in the cavity at the required level. An indicator shows if the sound level meter microphone is incorrectly inserted into the cavity, removing any potential for calibration error. An energy-saving automatic power off function helps ensure batteries last for up to two years.

Both the CEL-120/1 and CEL-120/2 models accept all industry standard ½" microphone capsules. Smaller ¼" microphones may be accommodated using the ½" to ¼" adaptor (CEL-4726). The relevant calibrator is also available as standard with Casella's range of noise monitoring kits.
