Acoustic Calibrator PROTECTION-K (PROTECTION K)
 
Acoustic Calibrator PROTECTION-K is designed for the acoustic calibration and validation sound level meters.
 
Technical characteristics of the instrument acoustic calibrators PROTECTION-K:
 
Designed for acoustic calibration and validation sound level meters.
Methods of noise measurement instrument acoustic calibrator PROTECTION-K - in residential areas and in residential and public buildings. "
Similar requirements are contained in other regulations, both domestic and foreign.
The current practice is that users rarely use the instruments acoustic calibrator PROTECTION-K and other calibrators.Two main reasons:
- First of all - the metrological characteristics of the modern sound level meters are stable and proper operation of the instrument during calibration Calibration is not required.
- Secondly - the cost of the calibrator comparable to the cost sound level meter.
For the latter reason manufacturers do not include sound level meters calibrator standard with the unit. However, there are strong arguments in favor of the calibrators.
X ochetsya pay attention to the purely practical considerations.The use of an acoustic calibrator (including instrument acoustic calibrator PROTECTION-K) - the only way to verify the functionality of the measurement channel sound level meter, including a microphone.
Why is this test necessary? Our experience has shown that damage to the microphone, usually mechanical, was unexpectedly frequent cause of repair. It goes without damage may not be visible when viewed from the outside, and deflection - not so large as to be evident.
Less frequently, but there were cases of incorrect sound level meter calibration due to carelessness and superficial study of the documentation.
In both cases the result is the same. The user continues to use the device, a fault which will only find at the next verification. The result: the "best" case lost their work, and at worst - a conflict with the customers measurements.
Acoustic calibration check before starting the measurement and after the guarantee that the results of measurements obtained serviceable instrument.
An additional argument - that disputes up to litigation, which use the measurement results. The use of the calibrator will support your position in the conflict.
We believe that the competent operation of sound level meter is not possible without using an acoustic calibrator. So we offer an acoustic calibrator, "Protection-K", at a price affordable to anyone serious about the results of their measurements.
