Overview
The Rosemount 1054 dissolved oxygen analyzer is a microprocessor-based measurement and control instrument engineered for continuous monitoring of critical process parameters in water treatment, wastewater, power generation, and industrial applications. When equipped with the appropriate sensor modules, this analyzer measures dissolved oxygen, pH, ORP (oxidation-reduction potential), conductivity, percent concentration, and total free chlorine. The unit delivers real-time data and isolated 4-20mA current output for direct integration into process control systems.
Key Features
- NEMA 4X (IP65) weatherproof enclosure — corrosion-resistant, flame-retardant construction for harsh indoor and outdoor environments
- Front panel membrane keyboard with tactile feedback for intuitive operator access and configuration
- Multi-parameter measurement capability — supports dissolved oxygen, pH, ORP, conductivity, chlorine, and concentration monitoring
- Real-time display shows measured value in engineering units, temperature, alarm status, hold output, and fault conditions
- Isolated current output continuously expandable over the measurement range for direct or reverse action control
- User-configurable security — selectable security code protects settings against accidental or unauthorized changes
