The Caisson SL-200 is a high performance, integrating-averaging sound level meter, which has a very easy to use interface for quick and simple sound level measurements. The SL-200 is provided in a compact hard carry case, fully tested and calibrated ready for use.
The compact and ergonomic housing allows the SL-200 sound level meter to easily fit in the palm of the hand or alternatively, it can also be tripod mounted for longer periods of sound level monitoring. The LCD screen offers an intuitive and easy to read display, with the main reading being centrally displayed for quick and easy reference. Below that, a segmented analogue bar graph offers a real time display of changing sound levels and both the minimum and maximum levels are also clearly displayed, along with an elapsed time indicator and battery level. The front panel of the SL-200 is designed to be simple and uncomplicated, with three soft touch keys which turn the sound level meter on and off, access the menu, and change the response and frequency weightings. The last 10 sound level measurements can be saved into the SL-200's internal memory for recalling later if desired.
The fast and slow mode allow the response time of the SL-200 to be changed to suit the requirements of the user. The sound level reading is updated, based on the setting in the meter. In fast mode, the SL-200 updates it's sound level reading every 0.5 seconds. In slow mode, the sound level reading is updated once per second, which is useful where the sound pressure level is constantly changing, as utilising the slow mode will smooth out the reading, but the minimum and maximum sound pressure levels will still be captured and displayed on the LCD screen. The A and C frequency rating setting can alter the sound level meter's frequency response. In the A weighting, the SL-200 will follow the frequency response of the human ear at low levels. This setting will filter out most of the low frequency noise, thus replicating the human ear response more accurately. This weighting is more commonly used than the C weighting, and noise measurements made with this setting are usually in dBA. The C weighting is usually used to follow the human ear response at high noise levels and as a result does not filter out the low frequency sounds, hence this scale is used less often than the A weighting, and tends to be utilised predominantly around high levels of industrial noise. The C weighting scales are designated dBC.
With it's small design and high accuracy of measurement, the Caisson SL-200 offers a compact meter, which is fully featured and ideal for taking sound level measurements in a wide range of environments. The SL-200 complies with the IEC61672-1 Class 2 standard, and is made in Germany to exacting standards and specifications. At only 190g (with batteries), using the SL-200 is both convenient and easy to operate.
