JENSPRIMA innoCon 6500CL Residual Chlorine and Chlorine Dioxide Analyzer

Overview

The JENSPRIMA innoCon 6500CL is a robust, panel-mounted online analyzer engineered for continuous, real-time measurement of free residual chlorine, chlorine dioxide, and ozone in potable water, process water, and disinfection systems. It operates on the amperometric electrochemical sensing principle—where target oxidants undergo controlled reduction at a noble metal working electrode under applied potential, generating a current proportional to analyte concentration. This method delivers high selectivity, low maintenance requirements, and stable long-term performance without reagent consumption. Designed for integration into municipal water treatment plants, swimming pool management systems, food & beverage processing lines, and pharmaceutical water distribution networks, the innoCon 6500CL supports regulatory compliance through traceable calibration protocols and temperature-compensated measurements aligned with EPA Method 334.0 and ISO 7393-2 guidelines.

Key Features

• Amperometric electrochemical detection optimized for free chlorine, ClO₂, and ozone—enabling simultaneous multi-parameter monitoring using compatible innoSens 710 series sensors
• Dual-range measurement capability: high-resolution mode (0.000–2.000 ppm, 0.001 ppm resolution) and extended range (0.00–20.00 ppm, 0.01 ppm resolution)
• Integrated Pt1000 temperature sensor with automatic compensation and user-adjustable offset (±10.0 °C), ensuring accuracy across variable ambient and process conditions
• Industrial-grade flame-retardant housing (UL94 V-0 rated) with IP54 ingress protection—suitable for indoor and semi-outdoor installations in humid, dusty, or electrically noisy environments
• Intuitive menu-driven interface with backlit LCD (44 × 65 mm), supporting multilingual prompts and password-protected configuration access
• Auto-calibration functionality with 1-point or 2-point options, reducing operator dependency and improving measurement consistency
• Two fully independent relay outputs (SPDT, 5 A) with programmable Hi/Lo thresholds, hysteresis control, and status indication for alarm or control logic integration
• Dual isolated 4–20 mA analog outputs and RS485 Modbus RTU digital communication—enabling seamless connectivity to SCADA, DCS, or PLC systems
• Factory-reset function via single-button operation and wide-input power supply (90–260 VAC, 50/60 Hz) for global deployment flexibility

Sample Compatibility & Compliance

The innoCon 6500CL is validated for use with flowing aqueous samples delivered via the optional PA-711 flow cell, ensuring laminar, bubble-free sample presentation to the innoSens 710 sensor. It is compatible with pH ranges of 4.0–8.5 and total dissolved solids (TDS) up to 2000 mg/L. The analyzer meets electromagnetic compatibility (EMC) requirements per IEC 61326-1 (industrial environment) and safety standards per IEC 61010-1. Its operational design supports adherence to Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) frameworks when paired with audit-trail-capable data logging systems. While not intrinsically safe, it is suitable for non-hazardous area installation per IEC 60079-0.

Software & Data Management

The device operates autonomously without external software but supports configuration and real-time monitoring via its front-panel interface or Modbus-enabled supervisory systems. All calibration events, relay state changes, and output value logs can be timestamped and retrieved remotely via Modbus registers—facilitating routine QA/QC documentation and regulatory reporting. When integrated with compliant data acquisition platforms, the innoCon 6500CL supports 21 CFR Part 11-aligned electronic records through user authentication, audit trail generation, and output value verification workflows.

Applications

• Continuous monitoring of chlorine residual at water treatment plant effluent points and distribution system entry points
• Chlorine dioxide dosing control in pulp & paper bleaching and cooling tower biocide management
• Ozone concentration verification in bottled water ozonation stages and ultrapure water loops
• Disinfectant validation in pharmaceutical clean steam condensate and WFI (Water for Injection) systems
• Swimming pool and spa water quality assurance per EN 15288-1 and NSF/ANSI 50 standards
• Process water monitoring in semiconductor fab ultrapure water (UPW) sub-loops where oxidative species must remain within strict ppm-level tolerances

FAQ

What sensor types are compatible with the innoCon 6500CL?
The analyzer is designed exclusively for use with JENSPRIMA’s innoSens 710 series amperometric sensors—available in dedicated free chlorine, chlorine dioxide, and ozone variants.
Does the unit support automatic temperature compensation?
Yes—it includes an integrated Pt1000 temperature probe and supports both automatic compensation and manual offset adjustment (±10.0 °C) to correct for thermal drift in sensor response.
Can the 4–20 mA outputs be assigned to different parameters?
Each of the two isolated 4–20 mA outputs can be independently configured to represent any active measured parameter (e.g., free chlorine on Channel 1, ClO₂ on Channel 2) or derived values such as temperature or relay status.
Is the device suitable for outdoor mounting?
While rated IP54, the innoCon 6500CL is intended for indoor or sheltered panel installations; prolonged exposure to direct rain or solar radiation is not recommended without additional weatherproof enclosures.
How often does the sensor require calibration?
Calibration frequency depends on application severity; typical intervals range from daily (critical disinfection control) to weekly (stable municipal distribution monitoring), guided by local regulatory requirements and internal SOPs.
