SOUND LEVEL METER

Alat Uji Kebisingan

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.

Rangkaian alat ini memiliki dua jenis tipe tahan benturan keras dan tahan ledakan. Jenis tahan ledakan dibagi menjadi tahan ledakan yang aman secara intrinsik dan tahan ledakan yang aman secara intrinsik. Ini memiliki kartu SD 8G di dalamnya, dan dilengkapi standar dengan daya baterai AA. Pada saat yang sama, pengguna dapat memilih bank daya yang disediakan oleh perusahaan untuk memasok daya sesuai dengan kebutuhannya. Instrumen ini juga memiliki fungsi seperti merekam, mematikan waktu, penentuan posisi GPS, Bluetooth, dll

Fungsi

Sangat cocok untuk pengukuran kebisingan di tempat dari produk elektromekanis, kebisingan lingkungan, kebisingan lalu lintas, kebingan industri, dan kebisingan di tempat kerja.

Standar
