Castle dBAir Class 1 Environmental Noise Monitoring System
The Castle dBAir Class 1 Environmental Noise Monitoring System provides the user with all he/she needs to accurately perform assessments in compliance with BS4142, to monitor boundary noise, to monitor construction noise and to carry out compliance testing. The set contains the powerful smart Castle GA141 dBair Class 1 Sound Level Meter, a Class 1 calibrator, an electronic barometer, a weatherproof carry case, weatherproof microphone cable, weatherproof microphone protection and a heavy duty tripod. Additionally, a three-year licence is included for a Castle Cloud software Pro account for up to five users with five separate meters.
The Castle GA141 dBAir Class 1 Environmental Sound Level Meter can measure sound pressure between 20dB and 140dB over two overlapping 95dB linear ranges. Readings are precise to 0.1dB and the Class 1 microphone picks up frequencies between 10Hz and 20kHz. Different measurement parameters include average (Leq), maximum (Lmax), minimum (Lmin), peak, and percentile measurement across several adjustable limits. Frequency weighting can be adjusted between A, C and Z and the response time can be set at a variety of different levels from 10ms to 24h.
The 16GB internal memory on the Castle GA141E can save thousands of readings and these can be recalled in a graph format to the colour screen which also allows the user to operate the meter thanks to its intuitive menus. A particularly useful feature of the Castle dBair is the automatic wireless data transfer to the Castle Cloud online storage facility, accessible from anywhere in the world using the three-year software licence included in the package. This is particularly useful for remote monitoring when the system is left to take readings unsupervised.
In order to ensure accuracy, the GA607 Class 1 Calibrator produces two separate tones at 1kHz (94dB and 104dB) so the sound meter can be checked at two separate points in both ranges. A GA690 electronic barometer allows the user to compensate for atmospheric pressure as it measures between 0 and 1300mbar.
Several weatherproof accessories are included so the system can withstand the elements when left outside to monitor environmental noise over an extended period. A case for the whole set shelters the meter and accessories whereas specific microphone protection permits accurate measurement whilst preventing water ingress. A 3m microphone cable allows the microphone to be placed at the optimum location for capturing sound. Finally, a heavy-duty tripod holds the microphone up to 1.6m in the air.
The Castle dBair Class 1 Environmental Noise Monitoring System is available for two, four, and eight day monitoring as well as in a long term package which contains a spare battery pack and weatherproof preamplifier . Octave band analysis (1/1, 1/3) can be added to any option at the cost of £475.00.
