HIOKI CM4373-93 - Clamp Multimeter Kit, 2000 A AC/DC, 2000 V DC and Bluetooth

Key Specifications

Detailed Product Overview

The HIOKI CM4373-93 Clamp Multimeter PV Kit is designed for professionals who need to measure very large AC/DC currents and high DC voltages in one complete package. Combining the HIOKI CM4373-50 with the included Z3210 Bluetooth Adapter and P2010 High Voltage Probe, it is ideal for industrial power distribution, heavy machinery, EV charging systems, and photovoltaic applications. Its 55 mm jaws accommodate large diameter insulated conductors, enabling reliable measurement where smaller clamp meters may not fit. 

With the included P2010, the instrument can measure up to 2000 V DC in CAT III environments, enabling safe testing of photovoltaic strings and high voltage batteries. Without the P2010, voltage measurement up to 1000 V AC/DC covers industrial installations and general maintenance tasks. True RMS technology ensures accurate results even with distorted waveforms. 

Versatile multimeter functions

Beyond current and voltage, the HIOKI CM4373-93 also functions as a versatile multimeter: it measures resistance, capacitance, continuity, diode polarity check, and DC power. In photovoltaic systems, battery based applications, and other demanding DC environments, this makes it possible to check electrical values and power conditions with one instrument. Temperature measurement is supported with a K thermocouple such as the optional DT4910 Thermocouple (K). It also supports non contact voltage detection for a quick check for the presence of AC voltage, which is useful for an initial check at the measurement point but does not replace voltage measurement with test leads. Automatic AC/DC detection and advanced display options such as Max/Min/Avg, PEAK values, filter function, manual/auto hold, and pass/fail judgement simplify daily tasks and save time. 

The included L9300 test leads are designed with the user in mind. Their slide type mechanism allows the metal tips to be extended or retracted, making removable caps and the risk of losing them a thing of the past. This simplifies handling and enables a safe switch between short tips for higher CAT ratings and fully extended tips for tight measurement points. The display backlight makes readings easier in poorly lit distribution boards, control cabinets, and service environments. With an operating temperature range of -25 °C to 65 °C, the instrument can also be used under changing field conditions in outdoor and industrial applications. 

Bluetooth and safety ratings

With the included Z3210 Bluetooth Adapter, measured values can be transferred directly to a smartphone or tablet. In combination with the free GENNECT Cross app for Android and iOS, values can be stored, documented, and incorporated into reports directly on site. Values can be assigned to a measurement location or linked to a photo of the test setup, which simplifies later review during service work. The app also supports current waveform display on the mobile device as well as harmonic analysis for troubleshooting. In addition, measured values can be transferred directly into Excel or other applications using HID functionality. 

The CM4373-93 complies with CAT IV 600 V / CAT III 1000 V, and with the included P2010 it also supports CAT III 2000 V. Its rugged housing is rated IP54 for dust and splash resistance, ensuring safe operation on construction sites and in harsh outdoor conditions.
