The BK Precision 732A Digital Sound Level Meter is designed for testing sound levels for OSHA compliance, quieting equipment, or monitoring the roar of a stadium crowd. The 732A provides a range of 30 to 130 decibels in three convenient measurement ranges of low, medium, and high. This meter meets the IEC 651 Type II standards and includes both frequency weighting A and C and fast and slow time weighting. The two auxiliary ports provide either AC output, 1Vrms full scale, or DC output and 10 millivolts per decibel. All sound testing needs can be met with this unit.
