Unique iCAL single standard standardization - saving an average of 30 minutes per dayFlexible and convenient analysis, quick replacement of the trigger gun, battery powered operation - up to 800 measurements can be taken on a single chargeSPECTROTEST is a mobile arc/spark spectrometer suitable for many applications in the metal production, processing, and recycling industries. This mobile metal analyzer performs exceptionally well, especially when accurate metal analysis is required, when materials are difficult to identify, or when a large number of samples need to be measured.The spectrometer with integrated design of arc and spark combines many ergonomic advantages, making it safe and easy to operate on site. The lightweight excitation gun can quickly switch between arc excitation and spark excitation (arc/spark OES). Provide excitation guns with built-in ultraviolet optical systems for special measurement applications; In its latest version, it can also be used with arc light sources.This arc/spark spectrometer can even recognize low-alloy steels containing carbon in rapid arc excitation mode. In spark mode, SPECTRTEST enables analysis of carbon, phosphorus, and sulfur. And identify duplex stainless steel by analyzing nitrogen elements.
