Nady Systems recently debuted two new SPL meters: the digital DSM-1 and the analog ASM-2. Both units provide a full array of professional sound measurement features for accurate testing and evaluation in a broad range of applications.
The DSM-1 offers two level ranges of measurement between 30 dB and 130 dB, 32 to 8k Hz. The product’s features include an easy-to-read, four-digit LCD with selectable permanent backlight; selectable A or C weighting and fast or slow response; maximum hold selector with Hold button; alarm; internal battery tester; built-in, calibrated linear omnidirectional ½-inch electret condenser microphone; and treaded insert to attach to optional SMT-3 tripod or standard camera tripod. The DSM-1 uses a 9V DC alkaline battery with up to 50 hours of battery life, and comes with a foam windscreen and sturdy vinyl carrying case.
The ASM-2 features seven sound-level ranges, which provide measurements from 50- to 126 dB. A and C weightings allow users to check compliance with safety regulations and perform proper acoustic analysis. Other features include slow and fast response settings, built-in battery condition indicator, phono-type output jack and threaded insert.
The DSM-1 and ASM-2 began shipping in June 2005.
