Hioki CM4371 AC/DC Clamp Meter

Hioki CM4371 True RMS 600 A AC/DC Clamp Meter for the Toughest Situations Hioki clamp on meters are best-in-class measuring devices incorporating Hioki's expertise in current sensing technology. Model CM4371 is a 600A 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 is ideal for the clamp maintenance inspections of electrical and solar power equipment. Damage-resistant jaws A revised design features stronger jaws (the current sensor portion of the instrument) and a dramatic boost in the duration of the warranty from 10,000 to 30,000 open-close cycles to ensure the instrument will provide even more years of reliable use. Clamp open/ close test In this test, the jaws are opened and closed a specified number of times at the rate of one cycle per second. In addition, the test is continued until the jaws break to provide a better understanding of their strength. Tests like this help us improve the instrument's durability. -25˚C to + 65˚C Thanks to an operating temperature range that has been expanded from the previous design (which could be used from 0°C to 40°C), the CM4371 and CM4373 can be used in freezing temperatures or on the hottest summer days. Temperature test In this test, we verified that the clamp meter can operate for an extended period of time while taking normal measurement in the specified temperature range.   Dustproof and waterproof performance International Protection Code: IP54* *Jaws (current sensor portion): IP50 Measurement functionality is maintained despite exposure to sand or dust as well as water droplets
