Alat Uji Kebisingan Suara

Pengukur tingkat suara Digital Sound Level HY-114 dirancang untuk mengukur kerapatan frekuensi suara di area tertentu. Sound Level 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.

Pengukuran otomatis dan pemrosesan data kebisingan dapat direalisasikan oleh instrumen yang dikendalikan komputer. Ini memiliki fungsi pelindung elektromagnetik, anti-tabrakan, dan anti-ekstrusi yang baik, dan lebih cocok untuk digunakan di lingkungan bersuhu tinggi dan berpolusi tinggi.

  • certificate number: 2019S125-43.
