Utilizing a standard 9V battery as the power source, the Model 735 and 732A from B&K are hand-held sound level meters and incorporate an easy to read, back-lit LED display for clear reading in the darkest environments.
Both provide three convenient measurement ranges: Low 30 - 80 dB, Medium 50 – 100 dB, and Hi 80 – 130 dB, with an accuracy of +/- 1.5 dB. The meters meet the IEC 651 Type II specification and include frequency weighting A and C and fast and slow time weighting. Two auxiliary ports provide AC Output, 1Vrms full scale, or DC Output, 10mV/dB.

Specifications include a dynamic range of 50 dB, a frequency range of 31.5Hz to 8KHz, 0 – 40degC (32 – 104degF) operating temperature, and 10 – 80% RH. A 9V NEDA 1604 battery with approximately 50 hours of life supplies power. An optional BE-9 AC adapter is available. The units compact size (275mmL x 64mmW x 30mm”H) and light weight (6.5 oz including battery) makes them ideal for single-handed operation.
