Simple to Use
Just switch the instrument on and use one of the pre-defined setups for US, European or German standards. This simple integrating noise meter is very low cost but has high quality features you would expect on more expensive instruments. By using the latest digital technology, the meter has a single measurement range, so no adjustment is required. There is also an automatic calibration feature, unique to instruments of this type.

This integrating sound level meter can be used as a point and shoot type and downloaded to the included dB30 software as required.

The CEL-430.A2 is Class 2 instrument and compliant with the latest IEC 61672 standard for sound level meters.
