Sound Level Meter

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.

Sound Level Meter

Pengukur tingkat suara Digital HY114 dirancang untuk mengukur kerapatan frekuensi suara di area tertentu. Meter ini mampu menampilkan tingkat suara A dan tingkat suara C, Meter ini sesuai dengan standar Internasional IEC 651-1979 untuk persyaratan Kelas I, oleh karena itu, rentang aplikasinya luas: untuk uji mekanis, uji elektronik, uji kebisingan kendaraan dan pemeriksaan klakson kendaraan.
