About us

For over 30 years, Crydet has specialised in designing and manufacturing solutions for environmental monitoring. We are a family owned and operated company with customers in over 50 countries across all regions of the world. Our clients include a wide range of organisations, from academic institutions and small-to-medium-sized businesses all the way to some of the world’s largest companies.

Crydet Ltd was founded in 1994 by physicist Dr. Zoltán Csiki in Budapest, Hungary with the help of Klára Csiki. At the beginning, our company specialised in manufacturing gamma scintillation crystals, complete detector assemblies and related products that are used for the detection of radioactive materials. Today, we channel our decades of expertise into a complete range of solutions, from world class scintillation detectors to innovative environmental monitoring systems. As a family run company, customer satisfaction is very important to us and we pride ourselves in offering our clients a high level of flexibility and customisation.

As our customers have always been primarily international, we operate with a global mindset and are able to offer our services to clients anywhere in the world. Our products have shipped to and are in use on all continents of the world, with our customers including a wide variety of companies, institutions and government agencies within the fields of environmental monitoring, security, medical and healthcare services, well logging, aerial surveys, food safety and others. We also work closely with a number of international industrial partners to continually develop our products and processes.

Today, Crydet is owned by Dr. Zoltán Csiki and Klára Csiki’s children Zoltán Csiki Jr. and Krisztina Csiki who have been with the company since its founding. With the assistance of their administrative team consisting also of other family members, they are also responsible for Crydet’s day-to-day operations.

Our offices and factory are located in the Budapest metropolitan area, 20 kilometres from the Budapest International Airport and easily reachable from abroad via M3, M0 and M31.
