About the product

Integrating Sound Level Meter TYPE 6226 has been designed for environmental noise
measurement. TYPE 6226 can measure Equivalent continuous A-weighted sound pressure
level (LAeq), Single event sound exposure level (LAE), Percentile level (Lx) and Wave form peak
hold (Lpeak).
Applications include automobile, airplane and factory noise, quality control or some other tests.
TYPE 6226 has a RS-232C interface to connect with a printer or a personal computer. (To
connect to a personal computer, an optional firmware version-up is needed.)
Results of measurements are displayed on a LCD screen as a bar graph and numerical values.
TYPE 6226 can display wide dynamic range of 100dB, so that you don’t need to change ranges.
It is easy to use.

5.Carrying Case
1. Percentile level (Lx: L5, L10, L50, L90, L95), Lmax and Lmin can be measured at the same time.
2. Equivalent continuous A-weighted sound pressure level (LAeq) can be measured.
Environmental noise important to industrial health can be measured.
3. Wave form peak hold (Lpeak) can be measured (LCpeak included).
4. Wide linearity range of 100dB
5. Built-in RS-232C interface: Data processing with a personal computer is available (optional).
6. Built-in memory: Approximately 10,000 samples : 1000 sets of results
7. Large LCD screen with back-light. The display is clear to see and easy to understand.
