- Accessories
The Orbisphere GA2400/GA2800 EX oxygen (O₂) Electrochemical (EC) sensors are designed for process monitoring as well as laboratory analysis in the liquid or gas phases across. The Orbisphere GA2400 O₂ EC-sensor can be used for a wide range of applications from beer or soft-drinks production to rinsing of semiconductor waters in chip-manufacturing plants, reactor coolant systems in nuclear power plants etc. The GA2800 EX sensor is suitable for harsh environments from chemical or oil to petrochemical plants.
A small residual signal with unrivalled accuracy (±0.1 ppb) is made possible by the exclusive sensor design. Different pre-mounted membrane kits are available to fulfill any particular process requirements and O₂ measurement ranges required
