Operating at a standard 1000 Hz frequency, it offers three calibration levels—94 dB, 104 dB, and 114 dB—allowing precise adjustment of a wide range of SPL meters. Housed in a lightweight 3.53‑ounce shell (6.69 × 5.51 × 2.36 in), the unit fits easily into a pocket or tool bag. Powered by two AA batteries, it includes an automatic low‑power LED indicator to prevent unexpected shutdowns. The 13.2 mm cavity aligns with most microphone ports for quick, secure coupling.
