Are QNix® devices waterproof?
They are not suitable for underwater measurements. However, our devices are very robust and withstand demanding environments, such as in corrosion protection or shipbuilding. In addition, they are protected against dust and splashing water according to IP64.
Can the device measure on plastic or other non-metallic materials?
No. For such materials, we recommend an ultrasonic measuring device, which we do not currently offer in our range.
Does the measuring device need to be calibrated regularly?
There is no legal requirement for calibration. However, we recommend an annual inspection at our facility to ensure accuracy and to issue an up-to-date calibration certificate.
Can the devices measure on different materials?
Yes, our devices measure steel, aluminum, copper, and zinc. They are designed to be precise and easy to use. As a rule, no calibration or probe change is required.
Is there training or support available for the devices?
Yes, we offer training so you can make full use of our measuring devices. If you have any questions or issues, our support team is always available to assist you. Contact
Is the device delivered with batteries?
We deliver it with standard batteries. However, you can also easily use rechargeable batteries.
Which probe is suitable for very small geometries and measuring surfaces?
The QNix® 9500 with a pencil probe and customized user calibration is ideal for narrow or hard-to-reach areas.
Does surface roughness affect the measurements?
Yes, you should take that into account. With a model from QNix® 9500 Serie you can compensate for roughness using user calibration. A mean zero adjustment also provides more precise results here.
Can the devices measure on carbon (automotive)?
Unfortunately, that’s not possible. The rough structure of the material leads to inaccurate measurements.
What is the maximum surface temperature for coating thickness measurement devices?
Our devices cover a wide temperature range. They can be used at temperatures between -20 °C and +70 °C. Outside of this range, accuracy may decrease.
Which simple measuring device do you recommend?
The QNix® 4600 or the QNix® 5500 are robust entry-level models with easy operation and reliable results.
How is the data transmission carried out?
Via a USB interface cable. This connection has proven to be particularly secure and reliable.
Does the accuracy vary depending on the measuring range?
No, the accuracy remains the same regardless of the measuring range. You can find the exact values in our technical specifications.
Precision the industry relies on
Our coating thickness gauges take your production processes to the next level. They deliver precise measurements that help ensure quality and reduce costs. With QNix®, you can be confident that your measurements are reliable and your processes remain efficient.
