GreenPrima ProSan8200 Inline Turbidimeter

Overview

The GreenPrima ProSan8200 Inline Turbidimeter is an industrial-grade, continuous-monitoring turbidity analyzer engineered for precision and long-term reliability in demanding water quality applications. It operates on the 90° light scattering principle (nephelometry), compliant with U.S. EPA Method 180.1 and ISO 7027:2016 standards—ensuring traceable, internationally recognized measurement integrity. Designed for permanent installation in pressurized flow streams, the ProSan8200 delivers real-time turbidity quantification across a wide dynamic range (0–1000 NTU) without manual sampling or flow interruption. Its optical architecture features a stable 850 nm infrared LED light source with a rated service life exceeding 7 years, minimizing drift and calibration frequency. The instrument integrates a built-in pressure regulator (set to 15 PSI by default), enabling direct connection to municipal distribution lines, filtration skids, or process loops operating between 1–200 PSI—eliminating the need for external pressure-reduction hardware.

Key Features

• Optical design optimized for 90° scattered light detection per ISO 7027 and EPA 180.1, ensuring high sensitivity and minimal interference from color or absorbance
• Auto-ranging measurement capability with selectable resolution down to 0.0001 NTU—configurable via embedded firmware to match application-specific reporting requirements
• Integrated desiccant chamber and internal fan system actively manage internal humidity, preventing condensation-induced optical errors in high-moisture environments
• Dedicated air bubble suppression mechanism—mechanically and hydraulically tuned—to minimize signal noise caused by transient entrained gas in flowing samples
• Modular optical cell and electronics architecture enables field-replaceable components, reducing mean time to repair (MTTR) and supporting lifecycle maintenance under GLP/GMP-aligned service protocols
• Dual output options: galvanically isolated 4–20 mA analog signal (HART-compatible) and RS-485 digital interface supporting MODBUS RTU protocol for SCADA and DCS integration

Sample Compatibility & Compliance

The ProSan8200 is validated for continuous monitoring of potable water, filtered effluent, recirculating cooling water, pharmaceutical-grade purified water (PW), and clean-in-place (CIP) rinse streams. It accommodates inlet pressures from 1 to 200 PSI and operates reliably across ambient temperatures of 1–50 °C. Its IP66-rated enclosure ensures protection against dust ingress and powerful water jets—suitable for outdoor wall-mount deployment in pump stations, water treatment plants, and industrial utility corridors. Calibration verification is supported by reusable NIST-traceable calibration kits (formazin or AMCO AEPA standards), facilitating routine performance checks aligned with ASTM D6508 and USP <<1231> water quality guidance.

Software & Data Management

While the ProSan8200 operates as a standalone analyzer with local LCD display (backlit multi-line interface), its RS-485 interface enables seamless integration into centralized data acquisition systems. Firmware supports configurable response time (5–500 seconds), averaging window selection, and alarm thresholds—including automatic alerting upon desiccant saturation (detected via integrated moisture sensor). When deployed in regulated environments (e.g., pharmaceutical manufacturing or municipal drinking water facilities), the device supports audit-trail-ready operation when paired with compliant SCADA platforms—meeting documentation expectations under FDA 21 CFR Part 11 for electronic records and signatures where system-level validation is performed.

Applications

• Real-time turbidity monitoring at critical control points in drinking water treatment: pre-filtration, post-sedimentation, post-filtration, and final distribution reservoirs
• Performance verification of membrane integrity in ultrafiltration (UF) and microfiltration (MF) systems
• Continuous surveillance of cooling tower make-up water and closed-loop heat exchange circuits in power generation and chemical processing
• In-process turbidity trending during beverage bottling line rinsing cycles and CIP validation
• Compliance monitoring for wastewater discharge permits requiring turbidity-based effluent limits (e.g., NPDES)

FAQ

Does the ProSan8200 require periodic lamp replacement?
No—the 850 nm LED light source is rated for >60,000 hours of continuous operation and is not user-serviceable; no scheduled lamp replacement is required over the instrument’s operational lifetime.
Can the unit be calibrated in-situ without removing it from the pipe?
Yes—zero and span calibration can be performed online using certified turbidity standards introduced via the dedicated calibration port, preserving system integrity and minimizing downtime.
Is the pressure regulator adjustable to values other than 15 PSI?
The internal regulator is factory-set to 15 PSI for optimal optical cell performance and stability; field adjustment is not supported to maintain measurement repeatability and compliance with ISO 7027 hydraulic conditions.
How does the instrument handle temperature fluctuations in unconditioned outdoor installations?
The electronics module incorporates thermal compensation algorithms, and the housing’s thermal mass—combined with active desiccation—ensures stable optical path performance across the full 1–50 °C operating range.
What documentation is provided for regulatory submissions?
GreenPrima supplies a Factory Acceptance Test (FAT) report, NIST-traceable calibration certificate, Declaration of Conformity (CE/UKCA), and technical file summary supporting ISO 9001 and ISO/IEC 17025-aligned quality systems.
