Dissolved Oxygen Monitor 9437

The Dissolved Oxygen Monitor 9437 accurately measures the levels of dissolved oxygen in process feed water. It has been designed specifically for on-line use in power generation and related process plant.

• Monitors both high and low dissolved oxygen concentrations, therefore suitable for measurement during two-shift and base-load operations on power stations
• Fast response
• Disposable sensor and no routine maintenance
• Comprehensive diagnostics facility with in-built software protection

Dissolved Oxygen Monitor 9438

The Dissolved Oxygen Monitor 9438 accurately measures the levels of dissolved oxygen in process feed water. It has been designed specifically for on-line use in steam-raising and desalination plants and semiconductor water treatment. The 9438 is an accurate, automatic, reliable instrument that requires no maintenance and can be customer-programmed to monitor dissolved oxygen between the ranges 0 ... 20 µg/kg and 0 ... 20 mg/kg. The 9438 comprises a transmitter, a liquid handling system with environmental enclosure and a 24 V DC power supply for the calibration solenoid valve.

• Monitors both high and low dissolved oxygen concentrations
• Fast response
• Automatic calibration reduces manual operation
• Thermal protection protects the sensor in the event of cooling water failure
• Disposable sensor and no routine maintenance
• Comprehensive diagnostics
