Thermo Orion 2295 Process Phosphate Analyzer

Orion 2295 is a colorimetric analyzer that continuously measures phosphate online in water and process waters. Measurement is based on optical absorption at a wavelength of 470 nm. Monitoring boiler water phosphate dosing, cooling water treatment and corrosion and scale control in industrial process waters are the main areas of use.

The instrument automatically takes the sample, mixes it with reagent and measures it, so the phosphate value is monitored directly from the process with no need to take samples to the laboratory.

2295 features

• Measurement range: Between 0.2 and 50 ppm, accuracy 5 percent of reading or 0.5 ppm (whichever is greater)
• Reagent economy: Designed for about 45 days of operation between reagent changes
• Outputs: RS232 ASCII data transfer and two isolated 0/4-20 mA current outputs
• Response time: Less than 10 minutes per analysis
• Resolution: 0.1 ppm in all ranges

This design allows easy connection to the automation system on boiler feedwater and cooling water lines at power and industrial plants.

With online measurement, phosphate dosing pumps can be set according to the actual value, which balances chemical consumption and helps reduce the risk of deposits and corrosion on boiler and exchanger surfaces. Results are transferred to the control room through current output or serial communication, so operators can follow trends and respond to deviations in time.

With sample line, panel and cabinet integration at its İzmir facility, the instrument can be delivered as a field-ready system.
