iSV1101 sound level meter Introduction: With the development of technologies such as the Internet of Things and smart phones, acoustic measurement equipment should also be developed in the direction of intelligence, networking and materialization. The iSV1101 sound level meter transmits the measured noise data through WIFI. The receiving device can select smart phones, tablet computers, notebooks, and desktop computers. The powerful processing capabilities of these devices can be used for calculation and analysis, and the functions are powerful and flexible. The instrument can be combined with PC or mobile phone software (noise assistant APP software) to achieve total value analysis, statistics, spectrum analysis and other functions. Technical Parameters: Measurement range: 28dB ~ 133dB (A), 33dB ~ 133dB (C), 38dB ~ 133dB (Z) (with 2 × 10-5 Pa as reference, the same below) Frequency range: 10Hz ~ 20kHz This electromechanical noise: less than A weight 4μV, C weight 7μV, Z weight 13μV (with pre-stage and short circuit through 20pF capacitor) Frequency weighting: A, C, Z weighting Time weighting: F (fast), S (slow), I (pulse) Accuracy: Comply with GB/T 3785.1-2010, IEC 61672-1:2013 Level 1 and GB/T 3241-2010, IEC 61260-1:2014 Level 1 Display: 128×64 dot matrix OLED Data output: WIFI mode: AP mode, STA mode, transmission distance of 10 meters (distance may be reduced depending on the surrounding signal interference) Power: Lithium battery: After fully charged, it can work continuously for more than 6 hours; external power supply: 5V 1A USB interface power supply Dimensions: l × b × h (mm): 225 × 75 × 24 (mm) Quality: 205g Conditions of use: Air temperature: -20 ° C ~ +50 ° C Relative humidity: 25% to 90% Air pressure: 65kPa～108kPa
