ZR800 Oxygen Analyzers

Oxygen Analyzers, ZR800

Systech Illinois’ ZR800 oxygen analyzers are capable of measuring from 0.1ppm up to 100% oxygen in most industrial gas streams.

The ZR800 oxygen analyzers offers accurate, reliable and flexible oxygen analysis under the most demanding on-line operating conditions.

With a response time and accuracy unparalleled in the industry, the ZR800 has found wide acceptance in the electronics, semiconductor, food processing and gas manufacturing industries.

The ZR800 oxygen analyzers are specifically designed to provide ultra fast oxygen analysis and performance you can count on. Available in three different configurations:

  • Panel-mounted or bench-mounted oxygen analyzers
  • NEMA 4X / IP66 waterproof and weatherproof oxygen analysis units
  • 19 in. rack mount

All ZR800 oxygen analyzers utilise precision Zirconia Oxide sensors for accurate detection of oxygen.
