For a LIMITED TIME ONLY when you purchase the Martindale ET4500 Multifunction Tester you will receive a FREE Martindale VT25 Voltage Tester and a FREE LOKKITBASE Locking Off Kit. You may also select another FREE item from the 'Select on Offer' column on this page. Be quick, as this offer is only available while stocks last. 

The upgraded version of Martindale's ET4000 multifunction tester, the ET4500 is a fully downloadable installation tester.

With built-in loop Zs tables based on amendment 3, several advanced measurement modes, high accuracy technology and a number of additional useful features, this multifunction tester is ideal for use on domestic, commercial and industrial electrical installations.

The built-in memory of the ET4500 allows users to easily document testing data without jotting everything down. Via a simple USB connection with PC, this information can also be directly downloaded into Martindale's included ET-Link software* for further analysis.

A comprehensive suite of testing procedures is included in the Martindale ET4500. It can perform insulation resistance testing at 50, 100, 250, 500 and 1000V, continuity testing at 200mA and 8.5mA, loop resistance and PFC with dual display, TRMS voltage, frequency and phase sequence testing and - via the use of an optional earth testing kit (code ER2KIT/S) - can perform three wire earth resistance testing.

Test results are shown in two ways. The first is a full reading on the built-in graphical LCD display, while the second is a dual LED indicator that shines with a red light for fail and a green light for a pass.
