Liquid analysis as part of surface treatment

Hug Oberflächentechnik AG relies on the Teqwave T

Hug Oberflächentechnik AG uses the Teqwave T as a new, versatile solution for monitoring its passivation and degreasing baths. The Teqwave uses special sound waves to create an acoustic “fingerprint” of the high-quality concentration solutions. This allows it to take very precise measurements of the specific concentration and density that the liquid has during the treatment process.

The result

  • To ensure absolute process quality, the Teqwave measures in real time and the treatment baths can be readjusted at any time based on this measurement.

  • Now, all employees at Hug Oberflächentechnik AG can use the Teqwave easily and efficiently. The result: the guarantee of consistent measurements – no matter which employee is using the device.

  • The automatic documentation practically eliminates the risk of errors that go along with manual record-keeping of the measured concentration values.

The challenge

The old method involved indexing the concentration in the baths each day using an aerometer, also known as a plummet or spindle. This process included documenting the concentration values, which are crucial in achieving the desired process stability. The previous measuring and documentation methods were very time-consuming and could only be done by one specialist. Both the manual reading and documentation steps were prone to errors.

Our solution

Hug Oberflächentechnik AG was convinced by the Teqwave T and its smart solution for mobile concentration measurement. It only takes one device to monitor concentration values at numerous measuring points. As a result, product quality can be maximized at minimum costs. The mobile transmitter of the Teqwave T can operate for up to 8 hours without external power supply. Thanks to its customizable app design and preconfigured measuring points, it can be adapted to meet the production requirements.
