ChraLab Siever M9 Portable TOC Analyzer

Greater versatility of sampling modes and applications

The lightweight, compact design of the Siever M9 Portable Analyzer gives you the option for TOC analysis at various locations- at-line, online, or in the lab. It offers the same accuracy and compliance as the lab model, but it can be installed online for continuous measurement or carried to any location in the water system for troubleshooting. The M9 Portable has options for simultaneous Stage 1 conductivity testing and for four-second analysis with Turbo mode for fast response applications. For the pharmaceutical industry, Siever Validation Support Packages (VSPs) help you navigate the M9 validation process and enable a more efficient instrument implementation.
