Overview
The GreenPrima PROCON2000 Colorimeter is an industrial-grade, UV-VIS absorption spectrophotometric analyzer engineered for precise, real-time measurement of color intensity in aqueous matrices. It operates on the principle of standardized absorbance detection at defined wavelengths (typically 430 nm, per ASTM D1209 and ISO 6271), quantifying color in Pt-Co (Platinum-Cobalt) units — the internationally recognized metric for yellowness/hue assessment in water and wastewater. Unlike subjective visual comparison methods or reagent-based colorimetric kits, the PROCON2000 delivers objective, traceable, and operator-independent results. Its optical architecture employs a stabilized xenon or LED light source coupled with precision interference filters and a high-linearity photodiode detector, ensuring long-term photometric stability and minimal drift. Designed for continuous deployment in demanding environments — including municipal wastewater treatment plants, pulp & paper effluent streams, textile dye-house outfalls, and potable water distribution systems — the instrument meets functional requirements for regulatory compliance, process optimization, and environmental reporting.
Key Features
- True zero-reagent operation: Eliminates chemical consumption, hazardous waste generation, and associated disposal costs — fully compliant with green laboratory and sustainable operations frameworks.
- Multi-mode measurement flexibility: Supports manual spot checks, programmable timed acquisitions (e.g., every 15/30/60 min), and continuous real-time monitoring via integrated flow cell.
- Robust optical path design: Quartz flow cell and FPM-sealed optical windows resist fouling, scaling, and particulate interference; validated for stable performance in turbid, high-suspended-solid samples (e.g., activated sludge supernatants).
- Full automation suite: Auto-zeroing (using deionized water or air reference), auto-calibration (with NIST-traceable Pt-Co standards), auto-cleaning (pneumatic or liquid flush cycles), and self-diagnostic routines reduce operational overhead.
- Extended service life: Light source lifetime exceeds 10 years under continuous operation; no consumables required beyond periodic O-ring replacement (recommended annually).
- Rapid response: Full spectral acquisition and calculation completed in <5 seconds — enabling timely intervention in dynamic process conditions.
Sample Compatibility & Compliance
The PROCON2000 is validated for direct analysis of raw and treated waters without dilution or pretreatment in most cases. Compatible matrices include municipal sewage, industrial process water, cooling tower blowdown, seawater, drinking water, surface runoff, and leachate. Sample contact materials — quartz, polypropylene, FPM fluoroelastomer, 316L stainless steel, and borosilicate glass — conform to USP Class VI and FDA 21 CFR §177.2430 for food-contact safety. The system supports GLP/GMP-aligned data integrity through audit-trail-enabled firmware (optional), time-stamped event logging, and electronic signature-capable software interfaces. Measurement accuracy (<±5% F.S.) and repeatability (<±5% F.S.) comply with ISO 6271:2022 and ASTM D1209-21 for platinum-cobalt colorimetry. IP65-rated enclosure and ATEX Zone 1/2 optional certification ensure safe deployment in classified hazardous areas.
Software & Data Management
The embedded controller features an 8.5″ TFT color touchscreen (800 × 480 px) with intuitive HMI navigation and multilingual UI support (English, German, French, Spanish). Onboard 8 GB SD card stores >12 months of high-frequency data (1-min intervals) with timestamp, alarm status, calibration history, and maintenance logs. Data export is supported via USB mass storage or Modbus RTU over RS485 (slave/master configurable). Analog 4–20 mA output provides seamless integration into SCADA, DCS, or PLC systems with <0.5% full-scale linearity. Optional cloud connectivity enables remote configuration, firmware updates, and centralized dashboard visualization via secure MQTT or HTTPS APIs — fully compatible with IIoT infrastructure and Industry 4.0 data architectures.
Applications
- Real-time effluent compliance monitoring for textile dyeing facilities (per EU Directive 2010/75/EU IED)
- Process control in pulp bleaching stages to minimize chlorine demand and AOX formation
- Early detection of organic contamination in drinking water distribution networks
- Performance verification of activated carbon or ozone-based color removal units
- Regulatory reporting for discharge permits (e.g., US EPA NPDES, UK EA WFD)
- QA/QC in pharmaceutical water systems (PW, WFI) per USP and Ph. Eur. 2.2.58
FAQ
What color scale does the PROCON2000 use, and is it traceable to international standards?
It reports exclusively in Pt-Co units per ISO 6271 and ASTM D1209, with factory calibration verified against NIST-traceable liquid standards.
Can the instrument operate reliably in high-turbidity wastewater?
Yes — its dual-beam optical design and proprietary flow cell geometry minimize scattering artifacts; validation data available for samples up to 150 NTU.
Is remote calibration possible without physical access?
Remote calibration initiation is supported via Modbus command; however, physical standard introduction remains mandatory for metrological validity.
Does the system meet FDA 21 CFR Part 11 requirements?
With optional audit-trail firmware and electronic signature module enabled, it satisfies Part 11 criteria for electronic records and signatures in regulated environments.
What maintenance intervals are recommended for unattended operation?
Quarterly visual inspection of flow path and seals; annual O-ring replacement; biannual verification with certified Pt-Co standards — documented in onboard maintenance scheduler.
