Water-resistant (Except for the microphone) | Use of rechargeable batteries |
Guaranteed water-resistant to at least level IP54 (resistant to spraying water). Helps reduce failures caused by sudden rain showers.  * Mounting the All-weather windscreen or rainproof windscreen helps raise the water-resistant performance of the entire unit,so that the microphone will meet IPX3 specifications. | In these new models it is possible to use rechargeable batteries which make these meters environmentally-friendly. 24 hour continuous measurement is possible (when using eneloop? or dry alkaline batteries).  |
･ Please use the dedicated charger to charged eneloop? batteries. ･ When using eneloop batteries, please read the eneloop? battery instruction manual. ･ eneloop? is a registered trademark of Panasonic group. |
Continuous detailed measurements for one month
This meter can be used to conduct long-term measurements, such as environmental measurements. (If an AC adapter is used)
Example of detailed recording | If the Lp is measured at 100 ms intervals and the Leq is simultaneously measured at 10 min intervals over a 24 h period, the total size of accumulated data is approximately 74 MB (reference value) |
Functionality can be extended by a range of options
Additional functions can be added, such as simultaneous logging of raw data (100 ms Lp) and processed data(Leq and other indices), frequency analysis reverberation time measurement and long-term data recording.
