Thermo Orion AV88 pH, Conductivity and DO Analyzer
Measured parameters: pH, ORP (Redox Potential), Conductivity, Dissolved Oxygen (DO)
Measurement method: Potentiometric pH / ORP, Conductometric Conductivity
The Thermo Orion AV88 analyzer series measures pH, ORP, conductivity, resistivity, dissolved oxygen and ozone. Sold and serviced in Türkiye by Tetra.
Installation, calibration, spare parts and service in Türkiye come from Tetra; cabinet and panel integration can be done at our İzmir facility.
Technical information
- Measured parameters
- pH, ORP, conductivity, resistivity, dissolved oxygen, ozone
- Supply
- 24 VDC or 90–240 VAC
- Communication
- Modbus RTU, DeviceNet (depending on configuration)
- Output
- No output or two relays
AV88 is Thermo Orion's single-sensor-input process analyzer series. The same housing is configured as a pH, ORP, conductivity, resistivity, toroidal conductivity, dissolved oxygen or ozone analyzer according to the measurement type ordered.
It is used for continuous measurement at water treatment plants, cooling towers, boiler water, process water and lines with ozone disinfection. Models with relay output suit simple alarm and dosing control, and models with Modbus RTU or DeviceNet communication suit central monitoring.
AV88 features
- Separate model options for pH, ORP, conductivity, resistivity, toroidal conductivity, dissolved oxygen and ozone
- Configurations without output or with two relays
- 24 VDC or 90–240 VAC supply options
- Versions with Modbus RTU and DeviceNet communication
- Conductivity and resistivity options with different cell constants (K)
