Explosion-proof intrinsically safe sound level meter Model: HS5628BF
This instrument has two measurement methods:
1. Measurement method 1: Automatic measurement of Lp, Leq, LAE, Lmax, Lmin, E, DL. Measurement time can be set
It is 10s, 1min, 5min, 10min20min, 30min, 1h, 8h, 24h, Man (manual).
The measurement results can be displayed or printed, and the measurement data can be stored in 500 groups.
2. Measurement method 2: Continuously measure the equivalent continuous sound level Leq, and the measurement time interval can be set to 1s~10S.
The start time, end time and measurement interval of the measurement can be set via the panel buttons or via the computer.
The measurement results can be displayed or printed or transmitted to a computer for processing, and the measurement data can store 50,000 equivalent continuous sound levels.
3. Using digital detection technology to replace some traditional sound level meters, the stability and reliability are greatly improved.
