QbD1200+ Laboratory TOC Analyzer, 0.4 - 100.000 ppb, Hach (CAT#: STEM-AI-0694-YJL)

QbD1200+ Laboratory TOC Analyzer, 0.4 - 100.000 ppb, model QbD1200+ is manufactured by Hach. QbD1200+ is a laboratory TOC analyzer using UV lamp + persulfate oxidation method. The measuring range is between 0-100 ppm. It is suitable for industries with low sample concentrations such as pharmaceuticals, electric power, disease control, and tap water. The TOC analyzer has high repeatability, accurate measurement results, simple operation and easy maintenance, low cost of use, meets relevant pharmacopoeias and regulations, and can solve problems that have plagued customers for a long time. For example, when measuring low-concentration TOC, there will be problems such as poor repeatability, high cost of use, complicated maintenance and long calibration time, but these problems can be avoided by using the QbD1200+ laboratory TOC analyzer.
