Model ZOA 100

To measure O₂ in permanent gases at the % level, and providing that there are no combustibles in the gas, a Zirconium Oxide (ZrO₂) cell can be used. Ranges between 0-10ppm up to 0-98% O₂ can be measured.

Duty: to monitor the atmosphere for oxygen using a diffusion micro zirconium oxide cell.

This technique allows for continuous or intermittent use with very low maintenance.

There are several versions of ZOA 100 that are designed to be suitable for many applications. The unit can also be used as an oxygen detector.
