Hach's range of phosphorus analyzers which measure a range of different forms of phosphorus including phosphate and orthophosphate are designed to provide accurate measurements while being dependable, low maintenance, and cost effective. With a wide range of online phosphate analyzers Hach has products for every application.

The Hach® NP6000sc Phosphate Analyzer offers dependable and accurate measurement to meet regulatory requirements, maintain process control, and reduce operational costs. Designed for wastewater facilities, the NP6000sc features straightforward installation, simple maintenance, and optimized cleaning cycles that help you save time while maximizing uptime. Multiple range options are available to suit your process needs: LR (0.015 - 5.0 mg/L), MR (0.05 - 15.0 mg/L), and HR (1.0 - 75 mg/L).

The Phosphax sc is being phased out.
This model is perfectly suited for outdoor environments, making it an excellent choice for wastewater treatment applications., industrial water processes, and surface water monitoring, it features three specialized models for varied measurement needs. Choose from High Range (HR), Medium Range (MR), or Low Range (LR) models, covering tailored flow rates and detection windows for precise analysis.

Designed for clean water applications like drinking water and industrial settings, this analyzer offers reliable orthophosphate measurement. It is prognosys-ready, supports multiple sample streams, and comes in two models. The Low Range Model measures 4-3000 µg/L, while the High Range Model covers 0.2-50,000 µg/L as PO4.

The EZ Series is ideal for complex water quality applications, offering exceptional customizability to meet the specific demands of intricate processes. Perfect for managing phosphate in both drinking water and wastewater, these versatile analyzers handle up to 8 sample streams. They feature high concentration range capability with internal/external dilution and flexible methods for effective BNR and phosphorus precipitation processes.
Eliminate variables like sample filtration, timing, and sample location discrepancies for data consistency between online and lab measurements.
Routine tasks, such as reagent replacement, are now designed for effortless access – streamlining workflows, reducing downtime, and improving operational efficiency.
By extending both the low and high range, we’ve made our solution more versatile. This flexibility allows you to tackle a wider variety of applications with a single, reliable device.
Increased confidence in your results with the ability to remotely check that your sample is consistently supplied to your analyzer.
Easy installation and less mounting hardware with integrated compressor for filtration module sample pump and compressor consolidated into the analyzer.
