The SC-160 analyzer is an ANSI Type 2 sound-level meter and real-time octave band spectrum analyzer with a frequency range from 31.5 Hz to 16 kHz. With a single 100-dB dynamic range and a memory of almost 90 hours of 1-second measurements, it allows a complete check of HVAC equipment with no need for range switching, the company says. It can be used for NC, RC, RC mark II, NCB, and all descriptors used in HVAC product noise and community noise analysis, the manufacturer states.
