PTM400 Portable VOC Analyzer for Volatile Organic Compound Detection
The PTM400 Portable VOC Analyser is designed for professionals in environmental monitoring, industrial safety, and indoor air quality assessments, providing accurate and real-time measurements of volatile organic compounds.
Whether conducting site evaluations, ensuring compliance with health regulations, or assessing air quality in confined spaces, the PTM400 delivers reliable data in a compact and user-friendly format. Its portability allows for on-the-go testing, making it an essential tool for fieldwork and urgent assessments in various industrial and commercial settings.
Overview
The PTM400 portable VOC analyzer, combining chromatographic analysis technology with a hydrogen flame ionization detector, fully complies with the requirements of HJ1012-2018 and HJ38-2017 standards, and can be used to test total hydrocarbons, methane, non-methane total hydrocarbons and benzene series in ambient air and exhaust gas. The PTM400 is a highly integrated portable instrument that collects the sample to be tested and enters the quantitative loop, which is switched into different chromatographic columns for separation through valves. The total hydrocarbons and methane or benzene series enter the FID detector in turn, and the concentration of each component is measured respectively. The built-in processor obtains the values of total hydrocarbons, methane, non-methane total hydrocarbons and benzene series.
Features
