Description
Digital sound level meter according to EN 61672-1 class 2 with an unbeatable set of features. In addition to standard features, the SL-451 has a data logger and USB port. With a robust housing and moulded protective rubber case, this device is suitable for use in tough conditions. The device has a measurement range from 30 to 130 dB with auto-range function. The integrated data logger lets you store up to 32,000 measurements, which can transferred to your PC and processed using the software supplied. This lets you easily monitor sound levels on a long-term basis. The detachable microphone and the supplied 3 m extension cable enable measurements to be carried out in hard-to-reach places. The software of the SL-451 permits measurements and analyses to DIN 15905-5 to avoid risk of hearing loss due to high noise levels from electro-acoustic equipment.
