Chemical Detection Testing Technology (CDTT) is a handheld, fieldable piece of technology capable of quickly detecting heavy metals present in water sources, such as Hg, As, Pb, Cu, Zn, and Cd. The device utilizes Anodic Stripping Voltammetry (ASV) on modified Screen Printed Electrodes (SPEs). The device has been ruggedized in order to improve durability when in use on the field. All results are compared against Environmental Protection Agency (EPA) thresholds to output SAFE/NOT SAFE.
