TriOS


The high-precision optical sensor standard for the New Zealand water industry

Robust and precise, TriOS optical measurement technology is used globally to deliver real-time water quality data. Distributed, and supported throughout New Zealand by AFI

TriOS is a world-class range of optical sensors and spectrometers designed for real-time water analysis without the need for chemical reagents. The sensors provide immediate, reliable data for critical parameters such as nitrogen, carbon, turbidity, and dissolved organics, making them ideal for seamless inclusion in municipal and industrial water monitoring specifications.
As the official New Zealand distributor, the entire range is fully backed by AFI’s nationwide team. Our comprehensive support includes local stock holdings, technical consultation, rapid-turnaround servicing, and seamless integration into existing PLC and SCADA infrastructure.
Features include:
  • Robust and proven on municipal and industrial water plants worldwide and across New Zealand

  • Reagent-free optical measurement eliminating chemical consumables and minimising ongoing operational costs

  • Advanced automatic anti-fouling mechanisms ensuring long-term calibration stability and minimal manual cleaning

  • Direct digital connectivity allowing simple plug-and-play integration with standard industrial networks and protocols

  • Highly accurate multi-parameter analysis from a single robust probe

  • Seamless SCADA compatibility aligning perfectly with existing plant automation and standards like WaterView

Councils and industrial operators that implement TriOS sensors have the following advantages:

A proven and reliable hardware standard backed by specialised local support and automation expertise

Reduced operational expenditure through the complete elimination of chemical reagents and frequent manual sampling

Faster process response times due to instantaneous, real-time data feeds rather than laboratory delays

Localised peace of mind with AFI based right here in New Zealand

Minimised non-compliances thanks to continuous, high-accuracy tracking of critical parameters

Streamlined service cycles with comprehensive service agreements tailored directly to local council asset management plans

The TriOS story

In delivering automation and process control projects for city and district councils across New Zealand, AFI regularly observed that water treatment and environmental teams were struggling with similar monitoring challenges including:

  • High maintenance overheads and excessive downtime for traditional, reagent-based analytical instruments

  • Inaccurate or drifting data from low-grade sensors, leading to process inefficiencies or compliance risks

  • Long lead times for specialised instrumentation parts and overseas technical support

  • Difficulties cleanly integrating disparate sensor protocols into core PLC and SCADA systems

  • Frequent manual cleaning cycles required in harsh wastewater or raw water environments

This situation often resulted in gaps in process visibility, a high total cost of ownership, and frustration for maintenance teams who needed to constantly recalibrate or service delicate probes.

Recognising the need for a more rugged, precise, and digitally integrated solution, AFI partnered with TriOS. By combining TriOS’s industry-leading optical measurement technology with AFI’s nationwide automation and service capability, we provide New Zealand asset owners with a complete, reliable, and fully supported water monitoring standard.
