Overview
The DUBAN DB30-6228ILEQ Pulse Integrator Sound Level Meter is a general-purpose sound level meter that meets the level 1 standard for the measurement of exponential time weighted sound level. It also has the function of pulse sound level meter. The equipment is suitable for industrial environment noise measurement and environment noise census measurement, especially for sound level measurement of environment, machinery, traffic, ships and other noises.
Features
1. Meet the performance requirements of GB/T 3785, IEC 61672-2002 and JJG 188-2017 standards for level 1 sound level meters
2. With integration and statistical functions, a single measurement can store up to 800 sets of data, continuous measurement up to 6 days
3. Provide fast (F), slow (S) and pulse (I) three time weighting gear options
4. Adopt Digital Detection Technology to Significantly Improve Instrument Stability and Reliability
5. Equipped with large screen display, support dynamic scale display
6. Support Bluetooth printer for measurement data printing
7. Support data output via USB cable and Bluetooth for easy communication with PC
Principle
The sound level meter uses digital detection technology instead of the traditional sound level meter, collects sound signals by testing capacitive microphones, and uses frequency weighting (A weighting, C weighting, Lin linear) and time weighting (fast, slow, pulse) for sound level measurement to achieve high Stability and Reliability of noise monitoring.
Applications
Industrial environment noise measurement, environment noise census measurement, environment noise measurement, mechanical noise measurement, traffic noise measurement, ship noise measurement, industrial environmental protection, construction, teaching and research
Standards
GB/T 3785、IEC 61672-2002、JJG 188-2017
Steps
1. Select the time weighted gear (fast F, slow S, or pulse I)
2. Set range control (automatic or manual third gear)
3. Perform measurements, data is automatically stored
4. View the instantaneous sound level and analog meter display through the large screen
5. Accessing or printing stored data
6. Output data to PC for analysis via USB or Bluetooth
Notice
• Make sure the power supply is sufficient before use, and the device uses 5 AA batteries or 5V external power supply
• Operating environment temperature should be in the range of -10 ℃ to 50 ℃
• Pay attention to the range selection during measurement to avoid exceeding the linear range > 60dB
When storing data, pay attention to a single measurement of up to 800 groups, continuous measurement does not exceed 6 days
• Make sure the device connection is stable when using a Bluetooth printer or data transmission
