Martindale Trms AC Earth Leakage Clamp Meter

The Martindale AC earth leakage clamp meter is a new age device measures the current up to 60A AC/DC and voltage up to 600VAC/DC. The advanced jaw design minimises the influence of conductor position and shields against external fields from other conductors to give more accurate and consistent results. They also measure the difference between the currents flowing by displaying the ’leakage value’. Alternatively, clamping around the earth conductor displays the earth leakage current.
It includes TL16 test leads, a soft carry case, 2 x 1.5V alkaline batteries, and a user’s manual.
