Featuring an O2 fuel cell for oxygen measurement at the probe site, values are displayed and adjusted from the rack location. The PRO902C also uses an automatic purge of the filter and barrel that can be manually timed for blowback operation. The regulation of the filter temperature is performed by a dedicated, rack-mounted PID controller with alarm for user notification.

Key Features:

  • O2 fuel cell for oxygen measurement at the probe site
  • Automatically purges the probe filter and barrel
  • Filter temperature is controlled by dedicated rack mounted PID controllers
  • O2 levels are displayed and adjusted from the rack location
  • Heated sample line is not required
  • Properly operates in harsh, dirty environments
