Overview
The GreenPrima PROCON2000 Online Water Colorimeter is an industrial-grade, calibration-ready photometric analyzer engineered for continuous, real-time measurement of color in aqueous matrices using standardized UV-VIS absorption spectroscopy. It operates on the principle of spectrophotometric quantification at defined wavelengths (typically 430 nm and 525 nm) aligned with the Platinum-Cobalt (Pt-Co) color scale—also known as the Hazen scale—as specified in ASTM D1209, ISO 7887, and APHA Standard Methods 2120B. Unlike reagent-based methods, the PROCON2000 employs a dual-beam optical architecture with temperature-stabilized tungsten-halogen light source and high-stability silicon photodiode detection, enabling drift-free operation over extended deployment cycles. Designed for permanent installation in process streams or monitoring stations, it delivers traceable, repeatable color assessment without chemical consumption—making it compliant with ISO/IEC 17025 laboratory equivalence requirements when integrated into validated water quality management systems.
Key Features
- Calibration-ready architecture with factory-traceable Pt-Co reference standards and automated zero-point verification using air or deionized water
- Multi-mode operational flexibility: manual on-demand measurement, programmable interval sampling (1–1440 min), and event-triggered acquisition via external digital input
- Zero-reagent operation: eliminates hazardous waste generation, operator exposure risk, and consumable logistics—fully aligned with EPA Method 8026 and EU Directive 2000/60/EC (Water Framework Directive) sustainability criteria
- Optical path integrity maintained by quartz flow cell (10 mm pathlength), FPM-sealed fluidic interface, and self-cleaning ultrasonic transducer (activated pre/post measurement)
- Full system autonomy: automatic optical alignment compensation, thermal drift correction, pressure-compensated flow regulation, and fault-adaptive recovery protocols
- Extended service life: LED-stabilized broadband source rated for >100,000 hours; no moving parts in optical train; maintenance intervals ≥12 months under continuous operation
Sample Compatibility & Compliance
The PROCON2000 supports direct inline analysis of raw and treated waters—including municipal wastewater effluent, pulp & paper mill process liquors, textile dye-house discharges, potable water distribution networks, estuarine and coastal seawater, and surface runoff. Its wetted materials (quartz, PP, FPM fluoroelastomer, SS 316L, borosilicate glass) ensure chemical resistance to pH 2–12, oxidants (≤5 ppm Cl₂), and suspended solids ≤100 mg/L. The analyzer meets IP65 ingress protection, ATEX Zone 1/2 non-incendive classification (II 2G Ex db IIB T4 Gb), and electromagnetic compatibility per EN 61326-1:2013. All firmware and calibration records are audit-ready for GLP/GMP environments and support 21 CFR Part 11-compliant electronic signatures when paired with GreenPrima’s optional SecureLog™ software module.
Software & Data Management
The embedded controller features an 8.5″ TFT capacitive touchscreen (800 × 480 resolution) with intuitive HMI navigation, multilingual UI (English, German, French, Spanish, Chinese), and local data logging to 8 GB SD card (≥12 months at 1-min intervals). Data export is supported via USB 2.0 mass storage mode or Modbus RTU over RS485 (slave/master configurable). Analog output (4–20 mA, isolated, <0.5% FS accuracy) enables seamless integration into DCS/SCADA platforms. Firmware updates and remote diagnostics are enabled via optional Ethernet/WiFi gateway. All measurements include timestamp, temperature-compensated absorbance values, raw spectral snapshot (optional), and diagnostic flags (e.g., flow fault, turbidity warning, lamp aging index).
Applications
- Real-time compliance monitoring for discharge permits (e.g., NPDES, UK EA consent conditions)
- Process optimization in pulp bleaching stages and textile dyeing baths where color correlates with residual lignin or unfixed dye concentration
- Early-warning detection of organic contamination events in drinking water distribution systems
- Performance validation of activated carbon or ozonation units in advanced oxidation trains
- Long-term trend analysis of colored dissolved organic matter (CDOM) in watershed studies
FAQ
Does the PROCON2000 require daily calibration?
No—factory calibration is traceable to NPL (UK) Pt-Co standards. Field recalibration is recommended only after sensor replacement or every 6–12 months depending on matrix fouling potential.
Can it operate under variable flow conditions?
Yes—the integrated flow regulator maintains laminar, bubble-free sample presentation across 0.1–2.0 L/min; pressure compensation ensures stable readings up to 2 bar.
Is the quartz flow cell resistant to scaling in hard water applications?
Quartz exhibits negligible scaling adhesion; combined with ultrasonic cleaning and optional citric acid backflush (via auxiliary port), it sustains optical clarity in Ca/Mg-rich matrices for >18 months.
How is data integrity ensured during power interruption?
Non-volatile memory retains all configuration, calibration, and logged data; system resumes measurement within 45 seconds post-reboot without manual intervention.
What documentation is provided for regulatory submissions?
Factory test report, ISO/IEC 17025-accredited calibration certificate, CE Declaration of Conformity, ATEX Certificate of Conformity, and full electrical safety test records per EN 61010-1.
