Jt technology provides ecg cables and leadwires that are shielded and constructed to meet the standards for low triboelectric noise. Our cable jackets are made of medical grade tpu for durability and good flex life. For conducting materials, they are made of special materials in order to provide good physical and electrical performance. For defibrillation applications, appropriate resistors can be incorporated into the cable assembly and meet the 5kv lead-to-lead requirement of iec60601-2-4. All ecg cables and leadwires are fully tested in compliance of ansi/aami, ec53-1995 standards. 1pc per pe bag
