Gossen Z110P AC/DC Current Clamp Adapter, 0.1–100 A, 10 mV/A, DC–20 kHz

With a frequency response up to 20 kHz and a 100 A RMS measurement range, the Gossen Z110P current clamp adapter turns any multimeter with a millivolt input into a precise AC/DC current measuring instrument.

Overview

The Z110P is a clamp-on current probe that measures both AC and DC currents from 0.1 A to 100 A. Its output sensitivity of 10 mV/A allows direct connection to a multimeter or oscilloscope with a high-impedance input. The clamp jaw accommodates conductors up to 11.8 mm in diameter, making it suitable for a wide range of electrical testing applications.

What stands out

• Wide frequency range: DC to 20 kHz (-3 dB) for accurate AC measurements beyond mains frequency.
• Dual AC/DC capability: measure both alternating and direct current without changing instruments.
• Safety rated: CAT III 300 V / CAT II 600 V for use in industrial and residential environments.
• Long battery life: approximately 50 hours from a standard 9 V alkaline battery.
• Flexible power options: powered by a 9 V PP3 battery or an external 9 V DC supply.
