Sentinel PRO – Environmental Mass Spectrometer

Ensure plant safety by enabling leak detection and correction before any toxic hazard is created with the Thermo Scientific™ Sentinel PRO Environmental Mass Spectrometer. This next-generation environmental mass spectrometer is engineered to help plants monitor fugitive emissions of toxic organic vapors, protecting workers and surrounding environment from hazardous exposure.

The fast, accurate and reliable Sentinel PRO environmental mass spectrometer can monitor 100 or more sample points within 15 minutes. It features detection of several species-specific volatile organic compounds (VOCs) in the 1ppm – 100ppm range. Rugged fault-tolerant design ensures availability in excess of 99.7%, and simplified maintenance procedures make it easy to own. A single Sentinel PRO analyzer can replace an entire rack of discrete, less sensitive analyzers to improve detection and significantly reduce ongoing maintenance and operating costs.
Increased sensitivity, accuracy, precision and mass range:
  • Completely redesigned electronics, incorporating higher specification components
  • Capable of monitoring 100 or more sample points within 15 minutes
  • Species-specific VOC detection in the 1ppm – 100ppm . range
  • Reliable, fault-tolerant design for 99.7% higher availability
  • Significantly enhanced analyzer control
  • Enhanced connectivity with DCS systems and offline data manipulation packages

Features:

  • Provides a large number of sampling points that can be located near potential leak points (i.e. valve body, etc.)
  • Unique fast multi-threaded sampler (RMS) with 32 or 64 ports
  • Stable with automatic calibration interval from 30 to 90 days
  • Complete service access from the front of the system, effectively reducing the footprint
  • Small footprints don’t need a big shelter
  • Requires minimal maintenance
  • Thermo Scientific™ GasWorks software
