Overview
The GreenPrima PROCON 2000 Online Seawater Colorimeter is a robust, laboratory-grade optical analyzer engineered for continuous, reagent-free color measurement in marine and aquatic environments. It operates on the principle of UV-VIS absorption spectroscopy—quantifying color intensity by measuring spectral absorbance across the 200–800 nm range—and reports results in standardized Pt-Co (Platinum-Cobalt) units, fully compliant with ISO 6226, ASTM D1209, and APHA Standard Methods 2120B. Designed specifically for high-salinity, biofouling-prone seawater matrices, the instrument integrates an optimized flow cell with quartz optical windows and corrosion-resistant wetted materials to ensure long-term stability and minimal drift. Unlike benchtop colorimeters requiring discrete sampling, the PROCON 2000 delivers real-time, in-line monitoring with sub-5-second measurement cycles—enabling rapid detection of chromophore shifts associated with algal blooms, organic loading, or industrial discharge events.
Key Features
- Reagent-free operation: Eliminates chemical consumption, hazardous waste generation, and calibration drift from reagent degradation.
- Multi-mode measurement protocol: Supports manual on-demand analysis, programmable timed intervals (1 min to 24 h), and continuous cycle-based acquisition.
- Extended optical lifetime: High-stability deuterium-halogen dual-source lamp system with >10-year operational life; no consumables or lamp replacements required during normal service intervals.
- Fouling-resilient fluidics: Patented laminar-flow analysis channel with self-cleaning rinse cycles and inert wetted path (quartz, PP, FPM fluoroelastomer, SS 316L, borosilicate glass) minimizes cross-contamination from suspended solids or biofilm.
- Full automation suite: Integrated auto-zero, auto-calibration (using factory-traceable Pt-Co standards), auto-cleaning (pressurized water flush), self-diagnostic routines, and fail-safe recovery protocols.
- Industrial-grade controller: 8.5″ 800 × 480 TFT capacitive touchscreen with LED backlight, 8 GB SD data logging, USB export capability, and ambient operating range of 0–50 °C / <90% RH non-condensing.
Sample Compatibility & Compliance
The PROCON 2000 is validated for direct online analysis of seawater, brackish water, treated effluent, surface water, potable water, and industrial process streams—including high-turbidity and high-chloride matrices. Its optical design compensates for scattering effects up to 100 NTU without mechanical filtration, and its flow path accommodates sample pressures ≤2 bar and flow rates of 0–2 L/min. All wetted components conform to FDA 21 CFR §177.2440 (food-contact polymers) and EU Regulation (EC) No. 1935/2004. The system supports GLP/GMP-aligned data integrity via time-stamped audit trails, electronic signatures (optional), and Modbus RTU/ASCII over RS485 for integration into SCADA or MES platforms compliant with ISA-88/ISA-95 architecture.
Software & Data Management
Embedded firmware provides native support for analog 4–20 mA current loop output (isolated, ±0.5% accuracy, max 500 Ω load), two programmable relay outputs (5 A NO / 3 A NC @ 277 VAC), and bidirectional RS485 Modbus communication (Slave/Master configurable). Data are stored locally on the 8 GB SD card with timestamped CSV files (UTC-synchronized), including raw absorbance spectra, Pt-Co values, diagnostic logs, and maintenance event records. USB mass-storage mode enables drag-and-drop retrieval without proprietary software. Optional cloud connectivity (via external gateway) supports MQTT/HTTPS forwarding to AWS IoT Core or Azure IoT Hub for centralized dashboarding and anomaly detection using historical baseline modeling.
Applications
- Real-time monitoring of coastal desalination intake water for organic color surges preceding membrane fouling.
- Regulatory compliance reporting for harbor authority wastewater discharge permits (e.g., MARPOL Annex IV, EU Urban Wastewater Treatment Directive).
- Process control in pulp & paper mills—tracking lignin-derived chromophores in bleach plant effluents.
- Quality assurance in seawater aquaculture systems, where color shifts correlate with dissolved organic carbon (DOC) and nutrient loading.
- Early warning for harmful algal bloom (HAB) onset via detection of phycocyanin/phycoerythrin absorption signatures in estuarine zones.
- Validation of advanced oxidation process (AOP) efficiency in recalcitrant dye wastewater treatment (e.g., textile industry).
FAQ
What colorimetric standard does the PROCON 2000 report to?
It reports directly in Pt-Co units per ISO 6226 and ASTM D1209, with optional APHA/Hazen unit conversion enabled via firmware configuration.
Can the instrument be installed in explosive atmospheres?
Yes—the enclosure meets ATEX II 2G Ex db IIB T4 Gb (Zone 1) and IECEx requirements; optional ATEX-certified version available for Zone 0/1 classified areas.
Is field recalibration required?
No scheduled recalibration is needed; however, periodic verification using NIST-traceable Pt-Co reference standards (e.g., 10, 50, 100 Pt-Co) is recommended every 6–12 months per ISO/IEC 17025 quality management practices.
How is sensor fouling mitigated in high-biofouling seawater applications?
The system performs automated 30-second high-velocity water flushes between measurements and includes ultrasonic transducer option (PROCON-UFS add-on) for active quartz window cleaning.
Does the controller support remote firmware updates?
Yes—over-the-air (OTA) updates are supported via secure HTTPS connection to GreenPrima’s certified update server, with SHA-256 signature validation and rollback capability.
