While they all look the same from the outside, our unit has many important features that ensure a premium quality tester. Our carbon piles are made from the best quality, superior performing materials. Our steel parts are made with patented “constant-pressure/constant current” steel. The fasteners and soldering materials and assembly technology insure the components and connection stay secure. We use heavy duty 4 gauge welders’ grade cable wire where competitors may use lighter gauge cable. These superior components and design qualities offer greater stability and more accurate readings while minimizing heat build up.
