Before launching a new product, you want to be absolutely sure that it does what you are promising it will do. Finding out whether this is actually the case will involve carefully designed and highly professional testing. For more than 25 years now, Hielkema Testequipment has been providing top-quality testing systems for this purpose.


From climatic chambers to ovens
We specialise in temperature and climate simulation systems. We supply, develop, service and calibrate standard and walk-in test chambers for a wide range of companies across Europe, enabling them to test their products under extreme climatic conditions. We can provide the perfect solution for almost any application involving exposure to high and low temperatures, humidity, corrosion, vibration, light, water and dust. Our products range from temperature chambers and ovens to thermal shock chambers and HALT and HASS chambers. We can also build custom standard and large walk-in test chambers to meet specific customer requirements.


Product development and quality control
Our test systems are used for both product development and research activities, as well as for production processes and quality control. And our customers come from the most innovative sectors, including the automotive, electronic, communication, energy, aerospace and maritime industries. If your budget does not run to the purchase of your own chamber, we also offer the option of climate or temperature test chamber hire. Tests can also be carried out at our premises in Uden (Netherlands).
