Bas de Groot
Director of Sales & Marketing, Owner
Comtest was founded by our father, Hein de Groot. He has always been fascinated with electro technique, from boosting a little scooter with a moped engine to repairing radio and radar equipment in KLM cockpits. In 1985 Hein de Groot got the chance to start a company selling measuring equipment. Having bought a house and having a young family, this was a big thing to do. However, our whole family breathes entrepreneurship. We see possibilities as opportunities. Hein took the jump and launched Comtest. Soon he realized that clients who needed measuring equipment also needed test chambers. Selling chambers was the logical next step.
In 1999 Comtest wanted to focus on building and producing its own test chambers. We, -Rik and Bas de Groot- started helping our father. We bought a welding cart, drill string and milling machine and started producing. We learned by doing, sticking our feet in the mud. This was
a bonus because if we speak to our clients now, we know every little detail
about our product, how it is built and what it does. Nowadays, we have a very
skilled R&D lab, which invented our ‘Javelin Tip’ polystyrene absorbers for
improved performance and a cleaner workspace, and our patented oscillating wall
stirrer technology for reverb chambers.
Like our father, we are all about people. Our products must be of excellent quality and developed by forward thinking. This is preconditional to us. It’s people that make the difference. We are driven by stakeholder value, not shareholder value.
We are and will be a family business. Although we’re from a small place and a small country, we think big and act globally. Our Dutch factory in Zoeterwoude is where all our magic happens. A can-do mentality is what we have to offer. It’s in our DNA. We can, and we will make it work. We have been doing that for 40 years now and will continue to do so in the future. Together with you.
In our family business, we were taught that our products must be right down to the smallest details. Details that others often don't even notice but that make the difference between good and perfect. We do this with a Dutch entrepreneurial spirit from the village where Rembrandt's father's mill once stood. This is how we help companies protect and connect people all over the world. As in one big family.

“Comtest is extremely flexible, forward-thinking and fast.
We are satisfied with our EMC chamber, which is set up to
provide us with load possibilities far beyond anything possible
with third-party testing solutions. This makes our test execution
very close to real-life usage of our products.”
“NXP is located on the High-Tech campus in Eindhoven.
Here the electromagnetic spectrum is quite crowded.
Shielded rooms are essential to ensure reliable testing.
Our 3 Comtest RF-shielded facilities have never sat empty,
which speaks volumes regarding their value to us.”
“The clear and candor way Comtest
communicates, made it easy to
effectively determine the scope of
the project.”
“Comtest delivers a turn-key solution,
so there’s no risk of incompatibility or
subpar calibration.”
“The Comtest team was extremely motivated
to create a unique type of chamber system that
hasn’t been built before.”
“For the expansion of our testing capabilities we worked
with Comtest for the construction of a new,
oversized testing chamber. We chose to work with Comtest
based on their reputation for quality and the fact
that they’re a Dutch company.”
“At Emitech, there are over 40 different types of testing
chambers to fit any testing. Comtest has built many of them
and works very fast and thoroughly. They completed our latest
3M SAC setup within one week. We look forward to working
with Comtest on future projects.”
Our international team of technical consultants loves to get in contact with you and talk about your focus points for the very near future.

Our services include maintenance and validated testing. We recommend that both are executed by authorized personnel only. Our expert teams can perform preventive maintenance on RF-shielded doors, mode-stirrer systems, and positioning equipment such as turntables. We also offer validation services to see if your EMC test chamber or RF-shielded room still functions within its intended limits and avoiding unexpected down-time or product recalls at the same time.

A shielded room can perform conducted emission and immunity EMC measurements, eliminating harmful external influences, leading to more accurate and consistent test results. Being a Faraday cage, a shielded room will not only improve test results but will also form an excellent aid in protecting information and essential hardware. Comtest can assist governments, the military, financial institutions, and large corporations in protecting what matters most in critical situations. We offer the highest quality, sensitivity, and security before, during and after working with you.
