HIOKI FT3432 Portable Sound Level Meter

SOUND LEVEL METER The FT3432 is used in noise management by facilitating the measurement of noise in factories and schools, near machinery, etc., to ensure a more comfortable environment. Small enough to fit in a pocket and weighing just 105 g, the instrument measures sound level, equivalent continuous sound level, sound exposure level, maximum sound level, and C-weighted peak sound level. Basic specifications Applicable standards     IEC 61672-1: 2002 Class 2, JIS C 1509-1:2005 Class2 Measurement functions     Sound level, Equivalent continuous sound level, Sound exposure level, Maximum Sound level, C weighting peak sound level (measurement possible only when peak range is selected) Measurement times     1/5/10 minutes, or 1 hour Frequency weighting characteristics     A weighting, or C weighting Measurement level range     [Wide range] A weighting: 30dB to 130dB, C weighting: 36dB to 130dB [Peak range] A weighting: 65dB to 130dB, C weighting: 65dB to 130dB Frequency range     20 Hz to 8000 Hz Microphone     1/2-inch electret condenser microphone Time weighting characteristics     Fast or Slow Output     DC output connector: DC output: 3 V (full scale), 25 mV/dB, Output impedance: 50 Ω AC monitor output connector: AC output: 1 Vrms +600 mVrms, -400 mVrms (at 110 dB) (Upper limit: 1.8 Vrms), Output impedance: 600 Ω, Frequency weighting characteristics: Z weighting Power supply     LR03 (AAA) alkaline battery ×2, Continuous use 9 hr at wide range, R03 (AAA) manganese battery ×2, Continuous use 3 hr at wide range, Consumption: 80 mA Dimensions and mass     63 mm (2.48 in) W × 120 mm (4.72 in) H × 23.5 mm (0.93 in) D, 105 g (3.7 oz), (including batteries) Accessories     Wind Screen WS-14 ×1, Hand Strap VM-63-017 ×1, Windscreen fall out prevention rubber NL-27-014 ×1, Silicon Cover NL-27-026 ×1, Carrying Case 9757 ×1, LR03 (AAA) alkaline batteries ×2, Instruction manual ×1
