Sound Level Meter

Level 1 integral sound level meter, in line with GB/T 3785, IEC 61672-2002 and JJG 188-2017 standards. With integral and statistical functions, it can store 800 sets of data for continuous measurement up to 6 days. Support A, C, Lin Frequency weighing, Measurement range 25dB (A)~ 130dB (A).

IEC 651.2, ANSI 1.4.2, including "A", "C", "F" weighting and fast time weighting, supports four main Measurement parameters: ordinary sound level measurement (Lp), equivalent continuous sound level measurement (Leq), maximum sound level measurement (Lmax) and statistical sound level measurement (LN).

Microphone φ 12.7mm (1/2 ") test capacitive microphone, Frequency range 10Hz~ 20kHz, Frequency weight A weight, C weight, Lin (linear), Measurement range 25dB~ 130dB (A), range control automatic transmission/manual, divided into three gears, linear range > 60dB.

DB30-6228ILEQ is a 1-stage pulse integral sound level meter, which complies with GB/T 3785, IEC 61672-2002 and JJG 188-2017 standards.
