Sound Level Meter

Sound Level Meter adalah alat ukur tingkat suara kebisingan model HY-128 Series mengukur tingkat suara multi-fungsi digital, yang dirancang untuk mengukur frekuensi tekanan suara sesaat dan tingkat tekanan suara berkesinambungan.

Pengukur tingkat suara HY series adalah pengukur tingkat suara multi-fungsi digital, yang dirancang untuk mengukur frekuensi tekanan suara sesaat dan tingkat tekanan suara berkesinambungan, tingkat suara paparan, tingkat suara statistik, dll. Evaluasi akustik, alat uji kebisingan memiliki 4 mode kerja rata-rata integrasi, paralel integrasi, analisis statistik dan pengukuran 24 jam untuk dipilih pengguna. Instrumen ini juga menyediakan pembobotan frekuensi rendah opsional untuk pengukuran kebisingan radiasi sekunder.
