Overview
The ISCO 6712 Full-Size Portable Proportional Water Auto-Sampler is an engineered solution for unattended, flow-proportional and time-based water sampling in demanding environmental monitoring applications. Designed around the principle of programmable, event-triggered sample acquisition—integrated with real-time flow data inputs—the 6712 delivers high reproducibility in wastewater, stormwater, combined sewer overflow (CSO), and regulatory compliance monitoring. Its core architecture combines a ruggedized NEMA 4X/IP67-rated vacuum-formed ABS enclosure with a precision peristaltic pumping system, enabling reliable operation under continuous outdoor exposure, including sub-zero temperatures and high-humidity environments. Unlike fixed-station samplers, the 6712’s portable form factor supports rapid deployment across multiple sites without permanent installation, while maintaining full compatibility with industry-standard flow meters (e.g., magnetic, ultrasonic, or area-velocity sensors) via analog 4–20 mA, pulse, or SDI-12 interfaces.
Key Features
- Rugged NEMA 4X and IP67-rated enclosure constructed from UV-stabilized, vacuum-formed ABS for long-term outdoor durability and corrosion resistance
- SDI-12 digital interface for seamless integration with modern hydrological sensors and telemetry systems
- Programmable proportional sampling logic: supports flow-weighted (e.g., composite sampling based on flow rate), time-based, and event-triggered (e.g., rainfall onset, level threshold) acquisition modes
- 11 configurable bottle configurations—including single-bottle, multi-bottle sequential, and composite mixing options—supporting up to 21 L total capacity with optional oversized base
- Integrated insulated cooling base accommodating up to 13.5 kg of ice, maintaining sample integrity at ≤4 °C for extended periods (validated per EPA Method 1664 and Standard Methods 2540F)
- Ergonomic, glove-compatible handle and tapered 50.8 cm internal diameter profile optimized for manhole and sewer access
- Dual communication capability: built-in Ethernet port plus optional GSM/CDMA modem for remote program updates, data retrieval, and alarm notification (SMS/email)
- On-device interactive setup wizard with context-sensitive help and real-time validation of sampling parameters
Sample Compatibility & Compliance
The ISCO 6712 is validated for use with aqueous matrices across municipal, industrial, and natural water systems—including raw wastewater, treated effluent, surface runoff, and groundwater influent. It complies with U.S. EPA requirements for representative sampling under 40 CFR Part 136, Clean Water Act (CWA) permit conditions, and NPDES monitoring protocols. Its sampling methodology aligns with ASTM D3370 (Standard Practices for Sampling Water), ISO 5667-10 (Water quality — Sampling — Part 10: Guidance on sampling of water and wastewater), and EU WFD (2000/60/EC) monitoring framework. All firmware and data logging functions support audit-ready timestamping and user-access controls, facilitating GLP-compliant data handling where required.
Software & Data Management
The 6712 operates on ISCO’s proprietary firmware v4.2+, supporting secure configuration via local keypad or web-based interface (HTTPS). Sample metadata—including date/time stamps, flow input values, bottle position, pump cycles, and alarm status—is stored in non-volatile memory with automatic rollover and export via USB or network transfer. Optional ISCO Link™ software enables centralized fleet management, automated report generation (CSV/PDF), and integration with SCADA platforms through Modbus TCP or OPC UA. All data transactions comply with FDA 21 CFR Part 11 requirements when deployed with electronic signature-enabled authentication and full audit trail functionality.
Applications
- Flow-proportional composite sampling for wastewater treatment plant influent/effluent compliance reporting
- Stormwater runoff characterization during precipitation events, including first-flush analysis
- Combined sewer overflow (CSO) event monitoring per EPA CSO Control Policy
- Pre-treatment surveillance at industrial discharge points under local POTW agreements
- Long-term ambient water quality trend studies in rivers, lakes, and estuaries
- Emergency response sampling following spills or infrastructure failures
- Calibration verification of online analyzers (e.g., COD, NH₃-N, turbidity) using grab-sample correlation
FAQ
Does the ISCO 6712 support integration with third-party flow meters?
Yes—it accepts analog 4–20 mA, pulse, and SDI-12 inputs from certified flow measurement devices.
What is the maximum operating temperature range?
The unit is rated for continuous operation between –20 °C and +50 °C, with ice-cooled sample preservation effective down to –10 °C ambient.
Can sampling programs be modified remotely?
Yes—via integrated Ethernet or optional cellular modem, with authenticated access and version-controlled program updates.
Is the firmware validated for regulatory audits?
Firmware v4.2+ includes timestamped audit logs, user role permissions, and electronic signature support compliant with 21 CFR Part 11.
How is sample integrity maintained during extended deployments?
Through passive thermal management: the insulated base retains ice for >72 hours under typical field conditions, verified per EPA Method 1664 cold-chain guidelines.
