Supply Jiaxing Heng liter HS5628 integrating sound level meter

HS5628A type integrating sound level meter is a kind of universal sound level measurements exponential time-weighted sound level, but also integrating sound level meter can measure the average sound level of integrated average sound level meter and measure the sound exposure, its performance in line with GB / T17181-1997 and IEC61672-2002 standard sound level meter to two requirements. The instrument is compact, attractive appearance, features and more, can be used to measure ambient noise, it can also be used to measure labor protection, industrial hygiene and all kinds of machinery, vehicles, ships, electronics and other industrial noise. * The instrument has two measurements: 1. Measurement Mode 1: automatic measuring Lp, Leq, LAE, Lmax, Lmin, E. Measuring time can be set to 10s, 1min, 5min, 10min, 20min, 30min, 1h, 8h, 24h. Man (artificial). The results can be displayed or printed. It can store 500 groups of single data 2. Measurement Method 2: Continuous automatic measurement Leq, measuring the time interval can be set to 1s-10s, through the panel buttons or set the start time measurement by computer, end time and interval. Measurement results can be displayed, printed or exported to computer processing. It can store 50,000 equivalent continuous sound level two main technical performance microphone: Φ12.7mm (1/2 ") electret condenser microphone 2 test measuring range: 30dB ~ 130dB (A), 35dB ~ 130dB (C) 3 Frequency range: 20Hz ~ 10kHz 4 frequency weighting: A, C weighting 5 time weighting: fast (F), Slow (S) 6 detector features: digital detector technology, crest factor ≥3 7 级 range at high, medium, Low 3 files, each file ≥60dB high linear range: 70dB ~ 130dB in: 50dB ~ 110dB Low: 30dB ~ 90dB 8 * measuring time setting: measurement 1: 10s, 1min, 5min, 10min, 20min, 30min, 1h ., 8h, 24h.Man (artificial) automatic measurements:. Lp, Leq, LAE, Lmax, Lmin, E 2 measurement: Measuring interval for 1s-10s, automatic measurement Leq 9 * Display: 8 × 2 matrix 10 LCD digital display output interface: RS232 port printout 11 * Power: 3V (2 AA batteries) 12 Dimensions: l × b × h (mm) 160 × 52 × 25 13 Quality: 200g (with battery) 14 Working temperature: -10 ℃ ~ 50 ℃, relative humidity of 20% to 90%
