The Martindale ET4 is an excellent general purpose electrical tester, with a number of unique features that set it aside from similar products on the market. Firstly, it's compact, lightweight design makes it less bulky than some competing products, it has good balance in the hand and a simple selection switch to change between tests.
The open jaw clamp will read up to 200A and also features a powerful LED torch, which makes using in poorly lit areas easier and safer. Along with the standard electrical measurements this unit also features a non-contact voltage indicator, display hold and display backlight.
