Hioki CM4371-50 current clamp
Details
The Hioki CM4371-50 is an AC/DC current clamp with a jaw diameter of 33mm. The clamp can measure AC and DC current up to 600A, voltage up to 1000V (CAT III rating), measure resistance and capacitance, and check continuity in the 10Hz to 100Hz range. The CM4371-50 can also be used to directly measure DC power. The dual-range feature of the CM4371-50 enables even more precise readings in the lower-current range (< 20A). It is perfect for electricians looking for a compact, reliable device that can be used for everyday field work. Using the optional Hioki Z3210 Bluetooth adapter, the clamp can log readings to a device.
Furthermore, with the optional P2010 high voltage leads, the CM4371-50 can be used to enable DC voltage measurements of up to 2000V (CAT III rating).
