Description

Hioki clamp meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology.

The CM4373-50 is a 2000 A True RMS clamp meter that features stronger jaws, 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 2000 V (*1) is ideal for the clamp maintenance inspections of electrical and solar power equipment.

Easy! Just connect the Z3210 Wireless Adapter to your Hioki compatible instrument, to make it Bluetooth® ready.

Wirelessly connect Hioki-compliant instruments with a simple connection.
Transfer measurements to your smartphone or tablet and quickly create reports with field photos and drawings.

Convenient for Repeated Measurement and Recording Tasks!

Automatic hold function

In addition to being convenient when the display cannot be seen during measurement, when the measurement value is stabilized, the display value is automatically held until the next measurement, which is very convenient for repeated measurement and recording tasks.

DC High V Probe Mode

– Enables high voltage measurement up to CAT III 2000 V
– Safely measure solar installations like the mega-solar without interrupting the grid by simply connecting the DC High Voltage Probe P2000 to compatible Hioki clamp meters and digital multimeters (DMMs)

Wireless Communication Capability for even Greater Convenience

Wireless support

When the Wireless Adapter Z3210 is installed, Bluetooth® wireless communication is enabled. It transfers measurements to your smartphone or tablet and allows you to quickly create reports with field photos and drawings.

Assess transient currents at motor startup

The clamp meters can simultaneously measure inrush current in RMS as well as maximum crest values at motor startup and for welding currents.
The clamp meters automatically detect the duration of the inrush current (which can range from several dozen milliseconds to several hundred milliseconds) and measure the current during that interval, enabling them to yield more accurate
measurements than standard clamp-on meters whose measurement interval is fixed to 100 ms.

Harmonic measurement

When combined with GENNECT Cross (*2), you can perform simple harmonic analysis. Applications include problem analysis of power supply systems.
