Brookhuis Applied Technologies

Brookhuis Applied Technologies develops and manufactures the world’s leading instruments for real-time particle deposition monitoring — the measurement that tells you what actually lands on the product, not what floats past a sensor in the airstream. Our APMON sensor is the market-defining instrument for the ISO 14644-17 measurement standard. Our SUMON surface cleanliness monitor, CleanroomIQ calculation platform, and contamination consultancy capability complete a product and knowledge portfolio that no competitor has replicated.

We are not a broad cleanroom technology company. We are a focused global niche player in the one measurement discipline that determines whether a contamination-sensitive product is actually protected during production. The scientific foundation of our work — the Whyte-Agricola research, the ISO 14644-17 standard our team helped shape, and four decades of practical contamination analysis — is the reason organizations from semiconductor manufacturers in Asia to aerospace prime contractors in the United States choose Brookhuis. Our products have been deployed in the assembly of the James Webb Space Telescope. Our science is cited in regulatory submissions across three continents.

We are growing. And we are looking for people who want to build something that matters in a domain where the science is real, the problems are hard, and the impact is measurable.

Why People Choose Brookhuis

Science-led work that reaches the field
At Brookhuis, the gap between research and product is short. The physics of particle deposition that Koos Agricola developed over four decades is embedded in APMON firmware, in CleanroomIQ’s calculation engine, and in the alarm threshold guidance we give every customer. When you work here, you work on problems where the science matters — and where the output is a sensor deployed in a semiconductor fab, a medical device cleanroom, or a defense assembly facility. The feedback loop between what you build and what it does in the world is fast and direct.

Ownership and real responsibility
Brookhuis is a flat organization. There is no queue of approvals between a good idea and its execution. Whether you are a physicist validating a new deposition model, a data engineer building the next generation of CleanroomIQ, or a sales director opening a new market — you own your work. We hire people who want that responsibility, and we give it to them from day one.

A global niche with room to lead
Particle deposition rate monitoring is a growing field. ISO 14644-17 is less than five years old. The industries adopting it — automotive, semiconductor, aerospace, medical devices, electronics — are at different stages of adoption, which means the market is still being shaped. The people who join Brookhuis now are not filling established roles in a mature market. They are defining how a new measurement discipline is applied across the global cleanroom industry.

A privately owned company with a long-term view
Brookhuis has been privately owned and operated as a family business since 1920. That independence shapes how we invest, how we hire, and how we treat our people. We are not optimizing for a quarterly earnings report. We are building a company that will be the global reference for particle deposition measurement for the next generation — and we make decisions accordingly.
