Castle GA141E dBAir Class 1 Environmental Sound Level Meter

The Castle GA141E dBAir Environmental Sound Level Meter is specifically designed for environmental monitoring of noise, for example performing BS 4142 assessments, boundary noise monitoring and compliance monitoring. It can measure sound from 20dB to 140dB at frequencies between 10Hz and 20kHz with Class 1 level accuracy and 0.1dB resolution. There are two measurement ranges (20dB to 115dB, 45dB to 149dB) with a linear range of 95dB and the environmental monitoring capabilities are further enhanced by a very low noise threshold of 15dB.

It is possible to select A, C, or Z frequency weighting on the Castle CA141E and the user can also choose fast or slow response times (10ms to 24h). The measurement options on this sound meter are tailored for environmental monitoring as it can perform percentile measurement alongside timed noise assessment of various times of day. Lspl, Leq, Lmax, Lmin, and peak are just some of other options available on the meter. Two different variables can be assessed at once thanks to the dBAir’s simultaneous measurement function.

Readings taken with the Castle GA141E will be automatically saved to the huge 16GB internal memory. From there, they can be downloaded to a PC via the micro-USB connection and supplied cable or wirelessly transferred to the Castle Cloud online storage facility via a Wi-Fi connection. Compiled in the form of a simple spreadsheet, results are very easy to use whether accessed via the meter or through a PC. A large, colour, graphical display clearly shows sound readings and graphical interpretations as well as allowing the user to navigate the intuitive menus with simple push buttons.

The Castle CA141E dBAir is an extremely compact and lightweight sound meter despite its advanced functionality. The 16-hour battery life will last the user through a whole day on site and it complies with various regulations such as IEC 61672-1:2013, IEC1260-1:2014 and IEC61252:1993 amendment 1.
