Reliable Sampling for Compliance and Process Control
Automatic samplers are essential tools for collecting representative wastewater or stormwater samples over time. They support compliance with local and federal discharge permits by providing consistent, verifiable composite samples that accurately reflect system conditions. By automating sample collection, facilities can reduce labor costs, minimize sampling errors, and ensure complete documentation for regulatory reporting.


We offer a range of ISCO automatic samplers designed for precision, durability, and integration with flow monitoring systems. Whether you need a compact portable unit for field work or a refrigerated model for continuous monitoring, we provide the equipment and support to keep your sampling program compliant and dependable.
ISCO 6712 Full-Size Portable Sampler
The ISCO 6712 is the industry standard for automated wastewater and stormwater sampling. Its modular design and rugged construction make it suitable for virtually any sampling environment. The 6712 allows for flow-paced or time-paced sampling, with programmable routines that ensure flexibility and accuracy across applications.
- Compatible with multiple bottle configurations (single, composite, or multi-bottle setups)
- Weather-resistant enclosure for field durability
- Optional refrigeration module for temperature-sensitive samples
- Ideal for industrial pretreatment, storm water compliance, and environmental monitoring programs

ISCO 5800 Refrigerated Water Sampler
The ISCO 5800 is a stationary, refrigerated sampler designed for continuous wastewater monitoring and long-term compliance programs. It features an energy-efficient refrigeration system to preserve sample integrity and a corrosion-resistant enclosure for demanding treatment plant environments.

- Continuous temperature control for accurate preservation
- Large capacity for extended sampling periods
- Programmable for flow-paced or event-triggered collection
- Ideal for municipal wastewater plants, industrial discharge points, and laboratory verification sites
ISCO GLS Compact Composite Sampler
The ISCO GLS (Grab and Liquid Sampler) is a lightweight, compact composite sampler designed for quick deployment and short-term sampling projects. Despite its small size, it provides the same level of accuracy and programmability as full-sized units—making it ideal for temporary installations, storm events, or remote sites.
- Lightweight and battery-powered for field mobility
- Simple one-button programming for rapid setup
- Composite or discrete sampling modes
- Perfect for stormwater events, temporary monitoring programs, or mobile compliance verification

Integrated Sampling Systems

All ISCO samplers offered by TDMA can be integrated with compatible flow meters, DuraTrackers, and online monitoring systems. Through the TIENet® 306 Sampler Interface, these instruments work together to collect and log synchronized flow and sampling data—helping facilities meet the most stringent regulatory requirements while simplifying reporting and QA/QC validation.
TDMA provides full installation, programming, and maintenance services, ensuring each system performs reliably and stays compliant. Our team assists with calibration verification, bottle configuration, and data retrieval to make continuous compliance effortless.
