Overview
The pulse sound level meter is a multi-functional sound level measuring instrument that can measure both exponential time weighted sound level and pulse sound level measurement. Its performance meets the requirements of GB/T 3785 and IEC 61672-2002 standards for level 1 sound level meters, and also complies with JJG 188-2017 standards. The instrument is suitable for noise measurement and environment noise census measurement in various industrial environments, especially for sound level measurement in environment, machinery, transportation, ships and other fields, and can be used in industrial environmental protection, construction, teaching and research and other fields.
Features
1. Provide the choice of fast (F), slow (S) and pulse (I) three time weighting gears.
2. Adopting digital detection technology to replace traditional sound level meters greatly improves the Stability and Reliability of the instrument.
3. Equipped with a large screen display, the information is presented clearly and intuitively, and at the same time supports dynamic scale display.
Principle
The pulse sound level meter receives the sound signal through the microphone, uses digital detection technology to process the signal, supports A-weighting, C-weighting and linear frequency weighting, and performs measurement in the 20Hz-8kHz Frequency range. The instrument provides fast, slow and pulse time weighting selection, automatic or manual range control, linear range over 60dB, Measurement range from 30dB to 130dB, and instantaneous sound level and analog electricity meter are displayed through large-screen dynamic LCD.
Applications
Industrial environment noise measurement, environment noise census measurement, environment, machinery, transportation, ships, industrial environmental protection, construction, teaching and research
Standards
GB/T 3785、IEC 61672-2002、JJG 188-2017、IEC61672
Steps
1. Select the time weighting gear (fast F, slow S, or pulse I).
2. Set the frequency weighting (A-weighted, C-weighted, or linear).
3. Select the range control mode (automatic or manual).
4. Perform sound level measurement and read data through large screen display.
5. Export data using an output interface such as USB.
Notice
• Ensure that the instrument meets relevant standards before use.
• Power supply voltage is 5 AA batteries or external 5V power supply.
• Use conditions are -10~ 50 ° C to avoid operating beyond the range.
• Regularly check the microphone and interface to ensure measurement accuracy.
