Remote Atmosphere Measurement

The sentinel-Es and Sentinel-ESi from marathon sensors remote4ly measures oxygen content (PPM levels) for use in calculating dew point and oxidation reduction in applications running at temperatures or with environments too hostile or impractical to use in situ probes. with a replacement (not rebuild) cost less than one-third that of conventional probes, the sentinel-ES and sentinel-ESi are an ideal solution for trouble free and cost effective control of endo generators. * 10X faster response then conventional probes. * Upto 100X faster than reheat wells * No modification to your furnace or generator * Lowest sensor replacement cost * Simplest set-up and calibration available * No hidden maintenance kit. * No costly extras like burn-off, reference air or timers needed.
