CM4375 AC/DC CLAMP METER – Discontinued
The CM4375 has been discontinued. See CM4375-50 for updated models.
Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM4375 is a 1000A True RMS clamp meter that features stronger jaws, broader -25℃ to 65℃ operating temperature range and IP54 dustproof and waterproof enclosure to enable professionals to work quickly in tough situations including the development, repair, and maintenance of equipment and devices such as electric vehicles. Additionally, the high-voltage DC measurement capability of up to 1700 V (*1) is ideal for the clamp maintenance inspections of electrical and solar power equipment. Measured values can be sent to a smartphone or tablet using Bluetooth® wireless technology and displayed as waveforms in real time.
