  1. Petroelectrician


    This is such an advanced meter for low ohm and insulation resistance measurements, with easy to use features. If you are still using a crank type meter this is definitely the product to choose for your upgrade into the 21st century. It is a valuable tool to all industrial maintenance electricians, that will allow you the full gambit of voltage ranges in one meter , eliminating the need for a whole bag full of tools. 100V,250V,500V AND 1000V this will be a motor mans tool he cant live without. It is also handy when measuring load bank resistors where only a wheatstone bridge was able to go to these low values in the past. Get one today and be one of the first in your crew to come up with the correct diagnosis every time………………..

    ✔ Yes, I recommend this product.
