Overview
The GreenPrima Prosan 8200 is an in-line turbidimeter engineered for continuous, real-time monitoring of suspended particulate matter in liquid process streams. It operates on the 90° light scattering principle—compliant with EPA Method 180.1 and ISO 7027—ensuring metrological traceability and regulatory acceptability across municipal, industrial, and pharmaceutical water quality applications. Unlike benchtop or portable turbidity meters, the Prosan 8200 is designed for permanent installation in pressurized flow lines, delivering high reproducibility under dynamic hydraulic conditions. Its optical architecture features a stable 850 nm infrared LED source, minimizing interference from coloration or natural fluorescence commonly found in surface water, wastewater, or purified process water. The instrument’s closed-flow cuvette design eliminates air bubble entrapment and ensures consistent path-length geometry, critical for long-term drift stability and calibration retention.
Key Features
- Integrated pressure-regulated flow cell with factory-set 15 psi operating pressure (range: 1–200 psi), compatible with standard 1/4″ or 3/8″ tubing connections
- Auto-ranging measurement capability across 0–1000 NTU, with resolution configurable down to 0.0001 NTU for low-turbidity validation (e.g., ultrapure water in semiconductor or biopharma applications)
- Internal desiccant cartridge and active fan-based moisture management system—monitored continuously; desiccant exhaustion triggers audible and visual alarm plus relay output
- Modular optical head and electronics assembly enables field-replaceable components without recalibration, reducing mean time to repair (MTTR)
- IP66-rated NEMA 4X enclosure rated for outdoor or wet-location mounting; corrosion-resistant housing suitable for chlorinated or saline environments
- Factory-calibrated using NIST-traceable Formazin and AMCO AEPA standards; calibration verification kit supports >100 reuses without degradation
Sample Compatibility & Compliance
The Prosan 8200 is validated for use with potable water, filtered effluent, cooling tower make-up, boiler feedwater, clean-in-place (CIP) rinse water, and pharmaceutical-grade purified water (PW) and water-for-injection (WFI) distribution loops. It meets the performance criteria outlined in USP , EP 2.2.2, and ASTM D6508 for online turbidity surveillance in GMP-regulated environments. All firmware and configuration logs support audit trail functionality per FDA 21 CFR Part 11 requirements when integrated with compliant SCADA or LIMS platforms. The device undergoes electromagnetic compatibility (EMC) testing per IEC 61326-1 and safety certification per IEC 61010-1.
Software & Data Management
Configuration, diagnostics, and historical data review are performed via embedded web interface (HTTPS-enabled) or local serial terminal. The unit stores up to 30 days of second-by-second turbidity readings (configurable sampling interval), with timestamped event logs for calibration actions, alarm triggers, desiccant status changes, and power cycles. Data export is supported via CSV over USB or MODBUS RTU polling. When deployed in distributed networks, the Prosan 8200 supports secure remote firmware updates and parameter synchronization through TLS-encrypted MQTT brokers—enabling centralized fleet management across multiple treatment facilities.
Applications
- Real-time monitoring at key control points in drinking water treatment: pre-filtration, post-sedimentation, post-filtration, and finished water storage
- Early detection of filter breakthrough or media channeling in municipal and industrial filtration systems
- Continuous verification of membrane integrity in ultrafiltration (UF) and microfiltration (MF) skids
- Turbidity trending for predictive maintenance of clarifiers, dissolved air flotation (DAF) units, and coagulation/flocculation basins
- Compliance reporting for regulatory submissions (e.g., EPA SDWA Tier 2 reporting, EU Drinking Water Directive Annex I monitoring)
- Process water quality assurance in beverage bottling lines, dairy processing, steam generation, and sterile manufacturing suites
FAQ
What standards does the Prosan 8200 comply with for regulatory reporting?
It conforms to EPA Method 180.1, ISO 7027:2016, and ASTM D6508–17 for method-defined turbidity measurement.
Can the instrument operate in high-pressure industrial coolant loops?
Yes—its integrated pressure regulator accommodates inlet pressures up to 200 psi; default setpoint is 15 psi for optimal optical cell performance.
Is calibration traceable to national standards?
All factory calibrations are performed using Formazin and AMCO AEPA suspensions certified to NIST SRM 2102 and BAM RM-86.
How is moisture ingress prevented in humid or outdoor installations?
Dual protection: replaceable silica gel desiccant cartridge + thermostatically controlled internal fan that maintains dew point below ambient condensation threshold.
Does the device support integration into existing PLC-based control systems?
Yes—via isolated 4–20 mA analog output or MODBUS RTU over RS-485, with configurable scaling, damping, and alarm hysteresis parameters.
