Highly accurate and customizable oxygen measurement for all environments
The Orbisphere GA2800 EX oxygen (O₂) Electrochemical (EC) sensor is designed for process monitoring as well as laboratory analysis in the liquid or gas phases across.
With its large measuring possibilities the Orbisphere GA2800 EX O₂ EC-sensor can be used for a wide range of harsh environments from chemical or oil to petrochemical plants where oxygen measurement is critical.
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.
The GA2800 EX O₂ electrochemical sensor is mechanically resistant to pressure up to 100 bar due to Hastelloy material and FFKM/FFPM O-rings.
Benefits
Easy and fast maintenance
Traditional cleaning processes can take more than thirty minutes to complete. The GA2400 and GA2800 EX come with an innovative cartridge system that contains everything needed to complete membrane and electrolyte solution change in less than 5 minutes.
Low level oxygen measurement and unrivaled accuracy
The Hach Orbisphere GA2400 and GA2800 EX utilize an electrochemical oxygen sensor with a lower detection level of 0.1 ppb and unrivaled highly accurate readings of ±1%. This feature allows users to ensure control of low oxygen levels, for product and equipment integrity and avoiding corrosion.
Robust for harsh environments
The robust stainless steel or Hastelloy design makes the GA2400 and GA2800 EX sensor ideal for the most demanding applications. ATEX certification comes standard in all GA2800 units, making the sensor especially suitable for harsh chemical environments.
