1ST Detect’s MMS 2000 is a highly selective and accurate process gas monitor designed to provide precise, real-time measurement of specific chemicals in a process stream. It is built for continuous, autonomous monitoring and recording of any excursions or environmental anomalies.

By selecting which ion masses to monitor, the MMS 2000 can continuously report the abundance of a set of chemicals in order to optimize yield or identify out-of-spec conditions. The data is disseminated in accordance with a user‐defined protocol which can be broadcasted to control rooms or mobile phones.

With our easy-to-use monitoring software, users can select any ion mass, ratio, or sum that will be monitored in real-time. An easy-to-view time trace of each chemical will be displayed and recorded. Preprogrammed alarm limits can be set to provide visual and audible alarms when the abundance of a chemical exceeds a preset limit (high or low).
