Pool & Spa Sensors

In pool and spa heating systems, temperature sensors are integral parts of a properly operating system. Whether the sensor is monitoring water temperature or flue temperature, sensor reliability and accuracy are critical.

QTI’s Validation Lab subjects parts to extreme environments to induce failures and has been tremendously effective in exposing design and manufacturing flaws in other manufacturer’s sensors. QTI’s ability to effectively identify the root cause of failure modes has led to enhanced design (through material selection and construction) and implementation of controls in the manufacturing process that ensure escapes do not occur.

QTI has the expertise to be an integral part of your design process, from engineering to validation and manufacturing. If you can dream it, we can build it. Contact us today to learn more about QTI’s wide range of custom solutions.
