The Thermo Scientific™ Sentinel PRO Environmental Mass Spectrometer can detect and locate leaks before they become dangerous hazards, ensuring plant safety. This next-generation environmental mass spectrometer is designed to assist plants in monitoring fugitive emissions of harmful organic vapors, therefore safeguarding workers and the surrounding environment from potential hazards.
The Sentinel PRO environmental mass spectrometer is quick, precise, and dependable, capable of monitoring 100 or more sample points in 15 minutes. It detects a variety of volatile organic compounds (VOCs) at concentrations ranging from 1 ppm to 100 ppm.
Simplified maintenance processes make it easier to own, and a robust, fault-tolerant design guarantees availability above 99.7 %. To increase detection capabilities and drastically lower maintenance and continuing running expenses, a single Sentinel PRO analyzer may replace an entire rack of less sensitive, discrete analyzers.
