Give your NH6000sc and NP6000sc the sample quality they deserve
The Hach FX6x0 sample filtration system protects your NH6000sc ammonia analszer and NP6000sc phosphate analyser by delivering clean, reliable sample from the point of collection. Solids and debris in the sample stream can compromise measurement accuracy and drive-up maintenance costs; the FX6x0 eliminates that risk by filtering samples to less than 0.45 microns before they reach your instrument. Designed specifically for the NH6000sc and NP6000sc, the FX610 and FX620 integrate directly with your analyser, which configures, and controls the system after cleaning or maintenance. The result: accurate water quality analysis, reduced downtime, and a simpler path to reliable nutrient monitoring.

Key features at a glance
• Filtration at the source: Removes particles to less than 0.45 microns before the sample reaches your instrument, protecting measurement accuracy, reducing the risk of blockages, and extending instrument reliability.
• Direct installation: Mounts directly in your aeration basin or effluent drain with no separate cabinet, no additional plumbing, and no dedicated floor space required.
• Simplified power setup: Draws power directly from your NH6000sc or NP6000sc analyser, eliminating the need for a separate power connection.
• Low maintenance intervals: Supports up to three months of unattended use between scheduled maintenance, with filter module replacement approximately every one year.
• Solids management: The FX620 includes an integrated air bubble cleaning module to reduce solids accumulation on the filter membrane.
• Indoor and outdoor rated: Designed for municipal wastewater treatment plants, with an operating range of -20 - 45 °C, heated sample hoses for freeze protection, and available in lengths of five or ten meters.

Our recommendation
Choose based on your top two criteria: application location and solids loading. For cleaner sample points like effluent channels, the FX610 delivers reliable filtration in a compact package, with room to upgrade later. For high-solids environments like aeration basins, the FX620 gives you automatic air-bubble cleaning from the start, so you protect your maintenance interval and keep your NH6000sc or NP6000sc analyser running accurately.
