SCARLET TECH ST-15D Class1 Sound Level Meter
Pengukur vs. Penganalisis
SCARLET TECH ST-15D Class1 Sound Level Meter atau Pengukur level suara adalah perangkat yang memungkinkan Anda menentukan akustik intensitas dan untuk mengukur tingkat tekanan suara, tetapi tidak tentu menentukan tingkat suara dalam kaitannya dengan toleransi manusia telinga. Pengukur level suara Scarlet Tech ScarletSound™ cocok untuk aplikasi profesional, termasuk pengukuran suara di tempat kerja dan pengukuran suara lingkungan.
Penganalisis suara menyediakan analisis pita oktaf untuk membantu Manajer Keselamatan mengidentifikasi dengan tepat sumber kebisingan dengan mudah dengan melihat ke yang paling relevan komponen frekuensi. Informasi domain frekuensi didasarkan pada teknologi DSP. ScarletSound™ ST-15D adalah yang Anda butuhkan.
