The ZXONIC ZX3100 is a lightweight, multifunctional Class 1 sound level meter designed for precision, portability, and ease of use. Featuring a low noise floor (<13 dB(A)), it delivers highly accurate measurements across a wide dynamic range of 20 to 140 dB(A) and a frequency range of 10 Hz to 20 kHz.
With parallel A, C, Z weightings and Fast, Slow, Impulse (F/S/I/I10) time constants, the ZX3100 is ideal for environmental noise monitoring, industrial assessments, and workplace safety checks.
