Company history

Our company has been around for more than 30 years.

We started in May 1991 as an association of entrepreneurs.
At that time, we gradually came to the market with several of our own products, which were relatively simple measuring instruments and also electrical network testers.

Our aim has always been to offer the customer good quality at a reasonable price.
We have taken this motto as our own and we believe that we are succeeding in fulfilling it.
ILLKO devices are known to most inspection technicians in the Czech Republic and Slovakia.
Our large and long-term customer is Germany, but you can also find our devices in Bulgaria, Denmark, Finland, Mexico, the United Arab Emirates, Canada, Turkey and other countries.

What we have achieved in more than 30 years is largely thanks to you, our customers. Thank you for your continued support and we will do our best to give you a reason to maintain your favor in the years to come.
