Introduction Types 2250 and 2270 are flexible hand-held analyzers that cover all your sound and vibration measurement and analysis needs - from the traditional uses in assessing environmental and workplace noise to industrial quality control and development. The high-resolution touchscreen allows you to easily navigate through the setup menu tailoring one of the many predefined templates to precisely your measurement requirements. The large dynamic range copes with both the loudest noises and those just above the noise floor and the frequency range, extended with the low-frequency option, spans...

Fora measured spectrum, single-number parameters, such as Noise Rating, Speech Interference Level and Loudness, can be calculated and displayed for noise impact analysis and limit comparison. A programmable generator is available for measurements requiring a sound source. You can select white or pink noise and set the upper and lower limits. 2-channel Measurements with BZ-7223 Type 2270 users can measure two spectra simultaneously with any combination of transducers. If the transducers are one microphone and one accelerometer, two independently scalable y-axes are available. Simple difference...
