The Kyoritsu 2433R is a compact leakage and load current clamp meter designed for electrical maintenance, troubleshooting, and inspection applications. It is ideal for measuring very low leakage currents as well as load currents without disconnecting the circuit, making it a practical tool for electricians, maintenance technicians, and facility managers.
The meter features True RMS measurement and a frequency selector function that helps reduce the influence of harmonics, allowing more reliable leakage current measurements in modern electrical installations. With measurement ranges from 40mA through to 400A and a minimum resolution of 0.01mA, the 2433R is well suited for identifying insulation deterioration, earth leakage issues, and unwanted current flow in electrical systems.
Its lightweight design, clear digital display, and simple operation make it easy to use in switchboards, distribution circuits, commercial buildings, and industrial facilities.
