Overview

Gasboard-9300 is a TDLAS process oxygen analyzer for reactors, centrifuges and other oxygen-sensitive equipment, offering selective, fast and stable O2 measurement. A corrosion-resistant conditioning system, Ex db IIC T6 Gb enclosure and automatic alarm and nitrogen-purge interlocks support inerting and process safety in Zone 1 and 2 areas.

Key Features

  • TDLAS technology for high measurement accuracy.
  • Fast response time for real-time gas concentration tracking.
  • Automatic interlock control with alarm and nitrogen purge replacement.
  • Explosion-proof design (Ex db IIC T6 Gb) for high safety in hazardous areas.
  • Low maintenance requirements and long service life.
  • Resistant to corrosive media: acids, alkalis, and organic solvents.
