Three-channel Direct-Pressure Air Tightness Tester
Three-Channel Direct-Pressure Air Tightness Tester adalah alat pengujian yang digunakan untuk mendeteksi dan mengevaluasi tingkat kebocoran serta kekedapan udara (air tightness) pada berbagai produk atau komponen menggunakan metode tekanan langsung. Dengan tiga kanal pengujian, alat ini memungkinkan pengujian beberapa sampel atau titik pengujian secara bersamaan untuk meningkatkan efisiensi dan konsistensi pemeriksaan.
Dilengkapi dengan sensor tekanan berpresisi tinggi, sistem pengaturan tekanan, tiga kanal pengujian, katup kontrol, fixture pengujian, serta layar digital untuk menampilkan hasil pengukuran, Three-Channel Direct-Pressure Air Tightness Tester mampu mendeteksi kebocoran secara akurat, stabil, dan konsisten. Alat ini banyak digunakan dalam industri otomotif, elektronik, kemasan, komponen rumah tangga, manufaktur, laboratorium kontrol kualitas, dan pusat penelitian untuk memastikan produk memenuhi persyaratan kekedapan dan kualitas sesuai standar ASTM, ISO, EN, serta standar pengujian terkait lainnya.
