Casella Cel 633 Environmental SLM
he CEL-633 meter for hire, is an advanced version of the popular CEL-632 logging sound level meter and is designed specifically to appeal to those users looking to do studies in environmental noise situations such as wind turbines or transportation studies. It can also be used to investigate specific noisy products with a view to controlling the noise output to meet mandated limits.
The standard half inch diameter microphones give the CEL-633 meters a single wide measurement range from 20 to 140 dB without the need to change ranges. This will greatly simplify the collection of results since it removes the requirment to select the right range before starting to record the changing noise levels. The preamplifier is removeable from the body of the meter allowing remote applications such as environmental noise measurements in waterproof kit cases.
All the CEL-633 meters measure with the Slow, Fast, Impulse and Peak responses simultaneously and calculate the time average noise level with the 3, 4 and 5 dB exchange rates in every run. The maximum, minimum and time average noise levels are calculated and stored for all measurements with all the valid combinations of frequency weightings and time responses so that the user will always have a full picture of what happened without having to be concerned about the correct setup configuration to use for a specific measurement. Measurements can be paused to remove unwanted noises from a survey and up to 999 separate measurements can be saved into the memory of the meter for later download to computer.
