Palintest Brings Precision Turbidity Testing To U.S. Municipal Water Market With Pending EPA Approval-Aligned Turbidity Expert

New white-LED variant of Turbidity Expert is designed to meet EPA Method 180.1 requirements for drinking water compliance monitoring, with U.S. utilities now invited to participate in pre-approval trials.

Palintest, the global leader in water testing and analysis solutions, today announced the U.S. market introduction of Turbidity Expert pending EPA approval a new variant of its established turbidity instrument, engineered specifically to meet the requirements of U.S. Environmental Protection Agency (EPA) Method 180.1 for drinking water turbidity monitoring. The instrument is currently pending EPA approval, and Palintest is now opening pre-approval trials to municipal water utilities and laboratories across the United States.

Following the successful global launch of Turbidity Expert ISO variant in early 2025, the EPA-aligned model has been developed to address a clear gap in the U.S. market: a modern, easy-to-use turbidimeter built around a white LED light source, in line with the optical specification required for EPA Method 180.1 compliance. Until now, U.S. utilities have had limited choice in suppliers offering instrumentation specifically designed for this regulated method.

Designed for U.S. Drinking Water Compliance

Turbidity Expert pending EPA approval has been engineered to meet and exceed the optical and performance criteria set out in EPA Method 180.1, the federally recognized standard for measuring turbidity in drinking water. With high-precision optics that deliver stable, repeatable readings even at low NTU levels, the instrument is built to support utilities at the moments where accuracy matters most: regulatory pass/fail reporting, compliance monitoring, and routine drinking water quality assurance.

Key benefits for U.S. municipal water operators include:

• Specification aligned with EPA Method 180.1 — white LED light source and optical design developed against the federally required method for drinking water turbidity.
• Accurate, repeatable measurements — stable readings at low NTU levels reduce variability and increase confidence in compliance reporting.
• Simple to use, easy to train — an intuitive interface and guided workflows reduce operator error, supporting both high-volume labs and smaller utilities.
• Operational efficiency — rapid measurement cycles, long-life optics, and straightforward calibration keep workflows moving with minimal maintenance.
• Built for real-world water systems — robust design performs reliably across drinking water plants, field operations, and compliance laboratories.

Inviting U.S. Utilities Into Pre-Approval Trials

Ahead of formal listing on the Federal Register, Palintest is offering eligible U.S. municipalities, water utilities, and contract laboratories the opportunity to trial Turbidity Expert pending EPA Approval in their own operating environments. The trial program is designed to give compliance teams hands-on experience with the instrument's specification, workflow, and reporting capabilities — and to ensure utilities are positioned to adopt the platform from day one once approval is confirmed.

"U.S. drinking water operators have told us they want a turbidity solution built around the precision, simplicity, and reporting confidence today's regulatory environment demands. Turbidity Expert pending EPA approval has been developed to deliver exactly that — and we're inviting utilities to evaluate it in their own facilities ahead of EPA approval.”
