The AII GPR-1500 Series Oxygen Analyzer is a wall mounted unit with NEMA enclosure. This single channel oxygen meter can be used with flow-through O2 cells for in-line gas analysis in safe as well as hazardous areas where ATEX approval is needed. The low detection limit of 0.05ppm offers low oxygen measurement down to a range of 0 to 10 ppm.
Ideal for clean gas applications and when used with the XLT oxygen sensor type it allows measurement in pure carbon dioxide.
The Analytical Industries long-life oxygen sensors are maintenance-free sealed electrochemical cells that don’t need top up of electrolyte and can be exchanged in few minutes.
