Deskripsi Harga Jual Casella Measurement CEL-120 Acoustic Calibrator

Casella Measurement was established during the reign of King George III, in 1799, by Cesare Tagliabue. A few years later, Louis Pascal Casella joined Cesare in partnership and the brand name of Casella was born. In these years, instruments to aid navigation, exploration, meteorological, medical research and photographic were invented and exported all over the world. A notable name on Casella’s early customer list was Charles Darwin who used many Casella instruments in his research.

During the 19th century, the product range continued growing and Casella even exhibited at the first “Great Exhibition” held in Crystal Palace, Hyde Park, London in 1851. Products on show included theodolites and surveying equipment.

The two world wars of the 20th century saw Casella’s expertise put to good use. Casella’s specialisation in compasses, optics and photogrammetry equipment was used by the military in both wars. By the time the 1950s began, Casella had progressed into producing equipment for dust monitoring to be used by the deep mining industry.

Three other significant years included 1952 when Casella invented the first ever personal sampling pump, 1972 with the world’s first electronic digital integrating noise meter and 1993 when Casella launched the world’s first real-time noise analysing device.

In 2006, Casella was taken over by an American company called Ideal Industries Inc. The long term future of Casella is to continue developing high quality instruments for the environmental and industrial markets, complementing the electrical, test and measurement instruments which Ideal Industries Inc develop. Soon after the takeover, Casella launched the CEL-350 Micro Noise Dosimeter, with a full array of features but contained within a smaller unit, making it perfect for use by customers such as industrial hygienists.

CEL-120 Acoustic Calibrator

The CEL-120 Acoustic Calibrator 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 instruments are providing consistently accurate readings necessary for monitoring to ensure compliance with workplace and environmental noise regulations.

The CEL-120 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.

Key Features:

Compliant with IEC 60942: 2003 and ANSI S1.40:2006
Class 1 & 2 accuracy versions
Digital technology ensures highly stable acoustic performance
Dual calibration level (Class 1 version) of 94dB and 114dB at 1khz
Rugged, ergonomic design
Simple to use with incorrect microphone insertion warning
Automatic power off to conserve life of battery, typically 2 years

The CEL-120 is compact and ergonomically designed with simplicity and ease of use being the highest priorities. Key features include a simple keypad for intuitive control, permitting calibration level changes when required. When used with instruments like the CEL-600 series, calibration routines commence automatically as soon as a calibration tone is detected to further simplify the task.

The CEL-120 uses a MEMS microphone and a digital feedback loop to 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.

The microprocessor control detects when the microphone is removed and automatically switches off the calibration tone. This conserves battery power, allowing batteries to last for up to 2 years of operation.

Both the CEL-120/1 and CEL-120/2 calibrator accept all industry standard 1/2“ microphone capsules. Smaller 1/4“ microphones may be accommodated using the 1/2“ to 1/4“ adaptor (CEL-4726). The relevant CEL-120 also comes as standard with our range of noise monitoring kits.
