⚔️ PCI-4060 vs PCI-4065 (Key differences)

Digits: 4060 = 5.5 digits; 4065 = 6.5 digits (10 times higher accuracy)

Isolation: 4060 = no isolation; 4065 = ±300 V isolation (safety)

Speed: 4060 = 60 times/second; 4065 = 3,000 times/second (50 times faster)

Status: 4060 = discontinued; 4065 = in stock (recommended)
