Holland sensor
KNOW YOUR METALS IN WATER WITHIN MINUTES
Mizu® measures dissolved metals on site, so you can act on a peak, a filter breakthrough or a release decision without waiting for the lab.
Built on patented Boron-Doped Diamond sensing. One platform, validated metal by metal.
SEE PEAKS BETWEEN LAB SAMPLES
A metal peak or filter breakthrough can pass unnoticed between two lab samples. Mizu gives a result on site within minutes, in time to act before the next step.
DECIDE WITHOUT WAITING FOR THE LAB
When discharge, reuse or release waits for a lab result, time and money are lost. Measure on site and make the call while the water is still in your process.
AVOID THE COST OF LATE DISCOVERY
Finding metals too late means rejects, lost metal, extra treatment or an exceedance. Earlier insight lets you adjust rinsing, treatment or recovery in time.
WHAT YOU GAIN WITH MIZU
Built on the Holland Sensor platform and patented BDD sensing.
Start with one metal, add more later. Mizu is configured per metal and water type. New validated metals are added by software update, not by replacing hardware.
Results within minutes, where you need them. Measure at the point where the decision is made. A result takes about 2 to 6 minutes, depending on the metal.
A result corrected for your water. A second measurement step corrects for most matrix interference, so the result reflects the metal in your water.
Sensitive enough to catch a peak. Detects metals at ppb level, with detection limits per metal in our specifications.
Every result documented. Results are validated, stored with date and location, and ready for reporting and trend analysis.
Fewer interruptions, less maintenance. The diamond sensor surface is chemically stable and fouls less than conventional electrode materials, so you measure more and clean less.
Mizu®
Real-Time Metal Monitoring, Built on a Scalable Platform
1. TAKE A SAMPLE
With Mizu®Flex, simply collect a water sample. Mizu®Fix is designed for fully automated inline sampling.
2. MEASURE
The sensor performs two measurements: one to determine the metal concentration and a second reference measurement to ensure accuracy.
3. GET RESULTS
Within minutes, results are automatically uploaded to the cloud, ready to view and analyse anytime, anywhere.
THE HOLLAND SENSOR PLATFORM ENABLES APPLICATION-SPECIFIC METAL MONITORING ACROSS INDUSTRIES.
From portable on-site measurements with Mizu®Flex to automated inline monitoring with Mizu®Fix. One scalable platform, designed for diverse industrial applications.

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.
