Brief introduction: Designed to simplify measurement of personal noise exposure. DBadge2 individual noise exposure meter is an ideal tool for evaluating various workplace noise, while enhancing confidence and improving productivity through wireless connectivity. DBadge2 is designed to collect as much noise exposure data as possible related to parameters during measurement for subsequent download and analysis. The user simply selects the relevant parameters to be displayed on the screen. Main functions: • Bluetooth ® 4.0 low-power wireless connections • Airwave apps for mobile devices like phones and tablets • multiple "analog" dosimeters • full color display • motor perception • pause function • data can be downloaded through USB cable connected to the charging base • upgraded and simplified Casella Insight plug-in with advanced noise analysis • audio event recording (Plus and Pro) • real-time octave frequency analysis (Pro) is optional Product parameters: • standard: ANSI S1.25:1991 R2007,IEC 61252 Ed1.1(2002-3) • current working range: 55.0-140.3 db (A) RMS • dynamic range: 96 db • peak measurement range: 90.0-143.3 db (C or Z weight) • sound exposure range: 0.0-6,100.00PaHours 0.0-22000000.00 Pa2Sec 0.0-100000.0% dose • frequency meter weight: A, C and Z, level 2 accuracy • time weight: fast, slow and pulse • exchange rate (Q) : 3 and 5 • threshold: 70-90 db, step 1 db (set by software) • standard level: 70-90 db, step 1 db (through software setting) • real-time clock: accuracy is better than 1 minute per month • lower limit range alarm value: 1 db below the lower limit range • overload alarm value: 140.4 db RMS • peak overload value: 143.4 db peak • stabilization time: within 3 seconds after power on Operating temperature range: 0 ℃ to + 40 ℃ (error range (+ / - 0.5 db) - 10 ℃ to + 50 ℃ (error range (+ / - 0.8 db) • environmental pressure range: atmospheric pressure from 85 to 112 kpa is less than 0.5 db plus or minus • humidity range: 30-90% range (no condensation) < 0.5 db • magnetic field: negligible Storage temperature range: - 10 ℃ to + 50 ℃ • battery: internal rechargeable battery, 800mAH • running time: using broadband mode is usually 35 hours Octave mode is usually used for 15 hours • charging time: the charging time in full discharge mode is less than 6 hours • maximum number of runs: 100 • storage capacity: internal USB flash memory -- 300 hours of running data (including time history analysis data per second) and 90 minutes of event recording • computer connection: full speed 12Mbps through base USB2.0 • size specification: 85mm * 54mm * 55mm • weight: 117g • environmental protection grade: IP65(with air vent)
