Dengan 10 channel analog terisolasi<\/strong>, alat ini mampu mengukur berbagai parameter seperti tegangan, temperatur (thermocouple), pulse, hingga rotation speed<\/strong> dalam satu perangkat\u2014menjadikannya ideal untuk aplikasi industri maupun R&D.<\/p>\nSalah satu keunggulan utama dari perangkat ini adalah kemampuan sampling hingga 10 ms pada semua channel secara bersamaan<\/strong>, sehingga mampu menangkap perubahan data yang cepat seperti fluktuasi beban atau respon sistem dinamis. Hal ini sangat penting dalam pengujian aplikasi seperti motor, inverter, hingga sistem EV<\/strong>.<\/p>\nSelain itu, Hioki LR8431 memiliki desain isolasi antar channel<\/strong>, yang memastikan pengukuran tetap aman dan akurat meskipun mengukur berbagai sinyal dengan potensi berbeda secara bersamaan. Fitur ini juga membantu mengurangi noise dan meningkatkan stabilitas hasil pengukuran, terutama di lingkungan industri yang penuh interferensi.<\/p>\nDari sisi kemudahan penggunaan, alat ini dilengkapi dengan layar LCD berwarna<\/strong>, penyimpanan data langsung ke USB flash drive atau CF card<\/strong>, serta kemampuan hot-swap media saat recording berlangsung<\/strong>. Hal ini sangat membantu untuk pengukuran jangka panjang tanpa harus menghentikan proses logging. Dengan kombinasi compact size, multi-channel capability, dan high-speed logging<\/strong>, Hioki LR8431 menjadi solusi ideal untuk:<\/p>\n | | | |
