Our services

Regular inspection of HovaCAL®, HovaPOR and HovaGAS devices is recommended to ensure long-term precision of the gas and gas-vapor mixtures. During the inspection, we check the functionality, clean any gas- and vapor-exposed surfaces, and adjust the built-in sensors and measuring devices. Please make an appointment with us!

In order to process your device, we require a completed declaration of contamination. It is very important that the information provided is complete.

You can use the form to fill out the declaration of contamination and send it to us.

After submitting the form, you will receive a summary as a PDF that you can print out and enclose with your shipment.

We recalibrate all devices from IAS GmbH and the balances we sell and issue factory calibration certificates. In doing so, the mass flow controllers for gases (MFC) and mass flow meters for liquids (MFM) built into the devices are traced back to national standards and standard measuring devices with the help of our reference devices. These reference instruments are regularly calibrated by accredited calibration laboratories. In addition, we offer the calibration of gas flow controllers according to DIN EN ISO/IEC 17025 by DAkkS-accredited calibration laboratories (DAkkS calibration). Please make an appointment with us!

If your HovaCAL® or HovaGAS requires repairs, your device is in good hands with us. We are also happy to help you with conversions, e.g. to larger gas flow ranges, or extensions. Please make an appointment with us!
