Hach, a water quality analysis company, has released the new NH6000sc Online Ammonium Analyser. This new offering is designed to optimise water monitoring in both the municipal and industrial sectors. The Nh6000sc focuses on reliability with minimal maintenance.
With rising demands for smarter, faster, and more efficient water quality measurement systems, the NH6000sc uses gas sensing electrode (GSE) technology to deliver highly accurate ammonium readings across a wide measuring range. Whether monitoring wastewater or drinking water, the NH6000sc ensures precise, stable, and dependable results with minimal user intervention.
The rising demand for smarter, faster, and more efficient water quality monitoring systems has led to the adoption of advanced gas sensing electrode technology to give extremely accurate ammonia readings across a wide measuring range.
Smart technology, simplified operations

Used in conjunction with other Hach products for optimal performance, the NH6000sc gives reliable readings with minimal human input
Designed for continuous operation at the measurement point, the NH6000sc is built to withstand the harshest outdoor environments. It uses environmentally controlled housing and a streamlined interface, so operators can expect biannual maintenance, saving both time and operational costs.
Automatic calibration, cleaning, and validation make this analyser an industry standout. The system also includes a grab sample verification feature, enhancing trust in the measurement and ensuring consistency between lab and online data.
Flexible measuring ranges and reliable samples
The NH6000sc has four selectable ranges:
- 0.02–5.0 mg/L NH₄-N
- 0.05–20 mg/L NH₄-N
- 1–100 mg/L NH₄-N
- 10–1000 mg/L NH₄-N.
This flexibility makes it ideal for low-concentration effluents, standard wastewater, and even high-strength industrial applications.
Pairing the NH6000sc with Hach’s FX610 or FX620 filtration systems ensures optimal performance. These lightweight, integrated filtration units collect and deliver ultrafiltrated samples directly to the analyser. The FX620 version includes air bubble cleaning to reduce fouling and improve reliability in tough conditions.
Both options are engineered to reduce user interaction – with cleaning needed only every three months under standard conditions—and come with smart flow detection to ensure consistent operation.
The NH6000sc forms part of Hach’s Claros™ Water Intelligence System. This means it is fully digital and compatible with Hach SC controllers. When connected to Claros, it enables real-time data access, process optimisation, and seamless integration with plant-wide monitoring systems, giving operators unprecedented control and confidence.
Built for harsh conditions
The NH6000sc has an IP55-rated enclosure. It can operate in temperatures ranging from -20°C to 45°C and in high-humidity environments. It is suitable for both indoor and outdoor installations, making it a versatile choice for utilities in diverse climates.
