Kyoritsu KEW-2300R Fork Current Tester — 100 A AC/DC True RMS

The Kyoritsu KEW-2300R Fork Current Tester is a compact and reliable solution for measuring AC and DC current up to 100 A in tight spaces where traditional clamp meters can’t reach. Its fork-style design slips easily around conductors in crowded junction boxes, panels, or cable bundles — ideal for electricians, maintenance technicians, and field service pros.

Ideal for current measurement in crowded panels and tight cable bundles.

Key Features

• True RMS Current Measurement — accurate AC and DC current readings on both clean and distorted waveforms. 

• Fork-Style Design — slim profile allows current measurement where clamp meters won’t fit. 

• Non-Contact Voltage (NCV) Detection — detects presence of AC voltage without direct contact and alerts with buzzer/visual signal. 

• Data Hold & Auto Power-Off — lock readings on screen for easier reporting and extended battery life. 

• Zero-Adjust Function — quickly zeroes DC current for accurate measurements. 

• Portable & Lightweight — pocket-sized tool that’s easy to carry and use in the field.

Why Choose the KEW-2300R

True RMS measurement ensures accurate results on non-sinusoidal loads such as inverter drives and PWM controls — a key advantage over average-responding meters. The fork design expands usability where space is limited and a traditional clamp can’t fit.
