The SPL-D3 is a sound pressure meter and logger. This device can be used as a 'stand-alone' device, but it is also possible to connect the SPL-D3 to a SPL5mk2 or SPL6 limiter. The display consists of high-efficiency multi-colour LEDs. This makes it clearly legible from a distance. The colour of the display changes from green, orange to red depending on the measured sound level.
