Casella 120 Acoustic Calibrator

Product Details

This field calibrator is compact and ergonomically designed with simplicity and ease of use in mind, with a rugged, over-moulded design for use in field environments, the CEL-120 Acoustic Calibrator is the smallest of its type in the world, producing a calibration tone at 1kHz.

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 instruments are providing consistently accurate readings necessary for monitoring to ensure compliance with workplace and environmental noise regulations. 

The CEL-120 is designed and manufactured to comply with the requirements of IEC 60942 and ANSI S1.40. 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. 

A simple keypad for intuitive control, permitting calibration level changes when required (CEL-120/1). A MEMS microphone and digital feedback loop to maintain the acoustic pressure. Microprocessor control detects when the microphone is removed. The CEL-120 has a low battery consumption, allowing batteries to last for up to 2 years of operation.

The CEL-120 in either a Class 1 (CEL-120/1) or Class 2 (CEL-120/2) variant and accepts all industry standard ½” microphone capsules.
