Mizu® Flex
Real-Time Metal Monitoring, Built on a Scalable Platform
Mizu® Flex is a portable metal monitoring solution built on the Holland Sensor Water Sensing Platform.
Powered by Boron-Doped Diamond technology, it delivers lab-grade measurements at low ppb levels directly in complex industrial water.
Designed for field operators and industrial laboratories, Mizu® Flex enables reliable, on-site insight to support compliance and process control.
Unmatched precision with Boron Doped Diamond (BDD) Technology
At the core of the Holland Sensor Water Sensing Platform lies our Boron-Doped Diamond (BDD) technology.
This chemically robust and electrically conductive material enables stable, low-ppb metal detection in complex water matrices where conventional sensors struggle.
BDD’s exceptional chemical stability and resistance to fouling make it particularly suited for industrial and challenging water environments — delivering laboratory-grade performance directly at the point of measurement.
The Holland Sensor Platform Enables Application-Specific Metal Monitoring Across Industries.
Mizu® Flex is the first portable deployment of the platform. The examples below illustrate industrial applications. Additional metals and industries are continuously being explored.
Paper & Packaging
Key metals: Copper (Cu), Nickel (Ni)
Paper and packaging processes introduce copper and nickel into wastewater through inks and additives. These streams are often highly variable, while monitoring is typically periodic and reactive.
Real-time monitoring enables continuous control over effluent quality, reducing treatment costs, improving compliance, and eliminating reliance on delayed lab results.
Metal & Electro
Key metals: Zinc (Zn), Chromium (Cr)
Metal processing and electroplating generate wastewater streams with elevated zinc and chromium levels. Monitoring is often lab-based and reactive, limiting real-time control.
Real-time metal monitoring enables continuous compliance control, reduces dependence on expensive lab infrastructure, and prevents regulatory exceedances.
Chemical & Polymer Industry
Key metals: Zinc (Zn)
In chemical and polymer production, zinc contamination in process water can disrupt operations and lead to product loss or disposal. Conventional measurement methods often fail in complex or variable matrices.
Real-time monitoring provides immediate insight into water quality, reducing downtime, minimising waste, and improving process stability.
Construction & Infrastructure
Key metals: Zinc (Zn), Copper (Cu)
Runoff from treated surfaces and roofing materials often contains zinc and copper. Structured monitoring supports environmental compliance.
Semiconductor & electronics
Key metals: Copper (Cu), Nickel (Ni)
Semiconductor manufacturing requires ultra-clean process water, where even trace metal contamination can impact production yield. At the same time, advanced materials introduce new metals into wastewater streams with strict discharge limits.
Real-time, ultra-trace metal monitoring protects yield, prevents costly batch loss, and ensures continuous compliance in high-value processes.
COPPER & SILVER IONISATION
Key metals: Copper (Cu), Silver (Ag)
Copper and silver ionisation is a proven method to control biofilm and Legionella in drinking water systems. It is widely used in critical environments such as hospitals, care institutions, hotels, and wellness facilities.
Maintaining precise ion levels is essential to ensure effective disinfection and regulatory compliance. Real-time monitoring enables continuous control, preventing under- or over-dosing and ensuring reliable system performance.
