XZR250 - Oxygen Analyzer        NOT CURRENTLY AVAILABLE

A compact zirconium-oxide analyzer to measure percentage level (0-25%) oxygen in combustion processes. The probe is manufactured from 316 stainless steel and can handle sample temperatures up to 700°C with an insertion length of 435mm. The sample is extracted to the sensor chamber and returned to the flue via the Pitot effect, so there is no need for instrument air. The analyzer uses our microion pump sensor (MIPS) technology and operates without the need for an air reference.

Product Features

  • Barometric pressure compensation
  • MODBUS as standard
  • Single or Dual 4-20 mA outputs
  • User configurable relays
  • Easy to swap sensor, requiring no special tools
  • Sensor exchange program
