MICHELL XZR250 Oxygen Analyzer

As a member of Process Sensing Technologies (PST) we also offer products and solutions from Michell Instruments.

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 micro ion pump sensor (MIPS) technology and operates without the need for an air reference.
