This product is now obsolete and has been replaced by the CEL-120 Acoustic Calibrator.
for a new standard
The CEL-110 is designed and manufactured to comply with the requirements of the new
IEC 60942 3rd edition 2003 Acoustic Calibrator standard. This latest standard ensures
accurate calibration over a wide range of temperature, humidity and pressure conditions,
typical of field work, making this calibrator an integral part of your measurement kit,
not just an accessory.
The field calibration of Sound Level Meters is an essential procedure when carrying out
any type of noise survey. Calibration with an approved Acoustic Calibrator, both before
and after each measurement sequence, ensures that meters are providing consistently
accurate readings. This type of measurement accuracy is necessary for monitoring within
noise exposure standards, including the Noise at Work regulations and environmental
noise regulations such as BS4142, as well as many other acoustic tests.

when microphone is inserted
Automatic power off to
conserve life of battery
Typical battery life 3 years
Calibration at 1kHz
The CEL-110 unit is compact and ergonomically designed with simplicity and ease of use being the highest priorities. Key features
include a simple keypad for logical control, and cursor keys permitting calibration level changes when required.
The CEL-110 uses a high quality microphone and a feedback loop to maintain the acoustic pressure
in the cavity at the required level. An additional ease-of-use design benefit, usually not found in
acoustic calibrators, is the provision of a display. This liquid crystal screen gives concise
information on calibration level, frequency and battery life. The design principles used result in an
error message on the display if the microphone is not inserted correctly into the cavity, removing
any potential for calibration error.
The microprocessor controlling the CEL-110 detects when a microphone is removed
from the unit and automatically switches off the calibration tone. This conserves
battery power, allowing a standard battery to last for up to 3 years of operation.
The calibrator is provided in 2 variants. The CEL-110/2 provides Class 2C performance and is suitable for
measurements made in accordance with the Noise at Work regulations. The CEL-110/1 provides dual calibration
levels (94dB and 114dB) to the Class 1 standard, which gives the additional accuracy required for environmental
measurements and more specialist acoustic requirements. This is the most accurate class of calibrator defined
by the standard for field measurement applications.
Both the CEL-110/1 and CEL-110/2 calibrator accept all industry standard 1/2 inch microphone capsules.
Smaller 1/4 inch microphones may be accommodated using the 1/2 inch to 1/4 inch adaptor (CEL-4726).
The relevant CEL-110 also comes as standard with our range of noise monitoring kits.
