Mizu® Portable Metal Monitoring
Built on the Holland Sensor Platform
PORTABILITY MEETS PRECISION
All Mizu® solutions are built on the Holland Sensor Water Sensing Platform — our shared technological foundation for real-time metal monitoring.
This platform combines Boron-Doped Diamond (BDD) sensing technology with dedicated electronics, control systems and secure cloud software. Every product we develop is based on this common architecture.
THREE PRODUCT LINES
Mizu® is available in three deployment formats, each designed for a different operational role.
Mizu® Flex
Portable deployment for industrial applications. Available today, Mizu® Flex enables real-time, low-ppb metal monitoring directly on site.
Mizu® Bench
For laboratory validation and method development. Used in controlled environments to test, validate and optimize monitoring applications.
Mizu® Fix
Stationary, in-line deployment for continuous monitoring within industrial processes. Currently under development as the next step in platform deployment.

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.
Packaging Industry
Key metals: Zinc (Zn), Nickel (Ni)
Coating, surface treatment and metal packaging processes can introduce zinc and nickel into wastewaterstreams. Application-specific monitoring supports discharge compliance and stable production processes
Metal & Electro
Key metals: Zinc (Zn), Chromium (Cr)
Electroplating and steel processing involve zinc and chromium. Real-time monitoring helps manage emissions and maintain regulatory compliance.
Chemical Industry
Key metals: Zinc (Zn), Nickel (Ni)
Catalysts and polymer-related processes mayintroduce zinc and nickel into process water. Reliable monitoring supports compliance and 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.
General Manufacturing
Key metals: Zinc (Zn), Nickel (Ni)
Metal finishing and machining generate zinc-and nickel-containing streams. Real-time insightimproves treatmentcontrol and discharge assurance.
Printing & Graphic Industry
Key metals: Copper (Cu), Chromium (Cr)
Printing plates and pigments mayintroduce copperand chromium into wastewater. Rapid verification supports compliance and operational continuity.
