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 rata-rata integral HY118 adalah produk yang ditingkatkan dari pengukur tingkat suara model sebelumnya HY108. Ini memiliki fungsi rata-rata integral manual. Hal ini terutama digunakan untuk mengukur tingkat suara tertimbang waktu, tingkat paparan suara, tingkat suara Persentase Akumulatif, paparan suara dan jumlah evaluasi Kebisingan dari dosis kebisingan.

Pengukur tingkat suara HY118 menggunakan memori internal untuk menyimpan hanya satu hasil pengukuran integral, dan tidak akan hilang setelah dimatikan. Setelah setiap pengukuran, maka secara otomatis akan menutupi hasil terakhir dan menyimpannya, dan hasil pengukuran juga dapat dicetak di tempat.
