JENSPRIMA innoCon 6800T Online Turbidity & Suspended Solids (SS) Analyzer

Overview

The JENSPRIMA innoCon 6800T is a dual-parameter online analyzer engineered for continuous, real-time monitoring of turbidity and suspended solids (SS) in liquid process streams. It operates on the 90° light scattering principle as specified in EN ISO 7027, ensuring metrological traceability to international standards for optical water quality measurement. Unlike transmission-based or nephelometric methods employing alternative scattering angles, the 90° geometry provides optimal signal-to-noise ratio for low- to mid-range particulate concentrations while minimizing interference from color absorption and bubble artifacts. The system comprises a wall-mounted controller unit and a submersible or insertion-type sensor (innoSens 810T/820T), designed for permanent installation in open channels, pipelines, or treatment basins. Its ARM-based embedded architecture delivers deterministic response times and long-term stability under variable ambient conditions — critical for unattended operation in municipal and industrial water infrastructure.

Key Features

• Compliant 90° light scattering detection per EN ISO 7027 for turbidity and SS quantification
• Dual-parameter output: simultaneous, independent measurement of turbidity (NTU) and suspended solids concentration (mg/L)
• Four selectable turbidity ranges (0–4.0, 0–40.0, 0–400.0, 0–1000.0 NTU) and four SS ranges (0–10.0, 0–100.0, 0–1000.0, 0–2000.0 mg/L) with automatic range switching
• High-resolution analog outputs: two isolated 4–20 mA loops (turbidity and temperature), load capacity up to 600 Ω
• Digital communication via RS485 interface supporting Modbus RTU protocol for integration into SCADA, DCS, or PLC systems
• Configurable dual-stage high/low alarms with adjustable hysteresis and relay contact rating of 5 A / 250 VAC
• Backlit dot-matrix display with intuitive bilingual (English/Chinese) menu navigation and real-time status indicators
• Robust mechanical design: IP65/NEMA 4X-rated controller enclosure; IP68-rated sensor with 316L stainless steel body and chemically resistant optical window

Sample Compatibility & Compliance

The innoCon 6800T is validated for use in potable water, wastewater effluent, industrial cooling water, recirculating systems, and pre-/post-filtration monitoring points. Its optical path and sensor geometry accommodate flow velocities up to 3 m/s and suspended particle sizes ranging from colloidal clays (<1 µm) to coarse organic flocs (>100 µm). Calibration is performed using formazin or polymer-based traceable standards compliant with ISO 7027. While not certified to USP <730> or EPA Method 180.1, the instrument meets functional requirements for routine compliance monitoring under EU Drinking Water Directive (2020/2184) Annex I parameters and supports GLP-aligned data integrity practices when paired with audit-trail-capable SCADA historians. Sensor immersion depth and flow conditioning must conform to ISO 7027-2:2022 recommendations for representative sampling.

Software & Data Management

The controller firmware supports local configuration via front-panel keys and remote parameterization through Modbus register mapping. All operational settings—including range selection, alarm thresholds, cleaning interval (1–999 hours), temperature compensation coefficients, and unit display preferences—are stored in non-volatile memory. The dual 4–20 mA outputs provide direct connection to analog input cards without signal conditioning. When integrated with enterprise-level data acquisition systems, the device enables time-stamped trend logging, event-triggered notifications, and export of CSV-formatted datasets for QA/QC review. Though the unit does not feature built-in data storage or cloud connectivity, its Modbus implementation ensures compatibility with third-party platforms supporting FDA 21 CFR Part 11-compliant electronic records (e.g., Ignition SCADA with digital signature modules).

Applications

• Municipal drinking water treatment: raw intake monitoring, coagulation/flocculation control, filter backwash optimization, and final distribution compliance verification
• Wastewater treatment plants: influent characterization, activated sludge process monitoring (MLSS estimation), clarifier performance assessment, and effluent discharge reporting
• Industrial process water: boiler feedwater pretreatment, cooling tower make-up control, semiconductor rinse water qualification, and food & beverage CIP validation
• Closed-loop systems: HVAC chilled water circuits, power plant condensate polishing, and pharmaceutical purified water distribution networks

FAQ

What standards does the innoCon 6800T comply with for turbidity measurement?
It implements the 90° light scattering principle defined in EN ISO 7027:2016, which aligns with ISO 7027-1:2016 for instrument design and calibration methodology.
Can the sensor be installed in pressurized pipelines?
Yes — the innoSens 810T/820T sensor is rated for continuous operation at up to 4 bar pressure and features a 1″ NPT male thread for direct insertion or flanged mounting.
Is temperature compensation applied automatically?
Yes — the integrated Pt1000 RTD measures fluid temperature in real time and applies algorithmic correction to turbidity and SS readings per ISO 7027 Annex B guidelines.
How often does the optical window require cleaning?
Cleaning frequency depends on fouling potential; the controller allows programmable intervals from 1 to 999 hours, with optional dry-air purge or ultrasonic cleaning interfaces available via OEM customization.
Does the device support HART communication?
No — it uses RS485 Modbus RTU and dual 4–20 mA analog outputs only; HART is not implemented in this model variant.
