Meters

Hioki clamp meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The CM4373 is a 2000A 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. Multiple measurement functions such as current, voltage, resistance, frequency, and voltage detection Simultaneously measure inrush current in RMS and crest values Damage-resistant jaws (current sensor) provide even more years of reliable use. Expanded -25 °C to 65 °C operating temperature range IP54 dustproof and waterproof enclosure Jaws (current sensor portion): IP50 Automatic AC/DC function helps boost work efficiency Remain alert to hazards with a red backlight and beeping tone Measure DC voltages of up to 1700 V
