Sindie standard complying petrochemical sulphur analyzers have two main types. The Sindie 7039 model is optimized for measuring samples in the very low range and the Sindie 2622 instrument can cover the whole concentration range from low ppm to high percantage levels. Thanks to the patented monochromatic optical design the unit requires neither helium purge nor a vacuum pump and having user-friendly software which can be reached through built-in screen. If it is required Sindie models are available with additional lead (Sindie + Pb) and chlorine (Sindie + Cl) elements, thus can support daily routine of a petrochemical laboratory. Measurements are featured by easy sample preparation, low maintenance demand and high reliability.
