Get to Know Us.

Experts in Temperature Sensing

At QTI, we’ve spent over 40 years building a reputation that goes well beyond the products we make. That’s why for us, solving any problem is no problem.

We understand that the highest quality products require mission-critical parts that refuse to fail. We also recognize that many of your competitors sacrifice the quality of their temperature sensors for cheap solutions that cost them big in the long run.

We’re here to ensure you don’t make sacrifices. That’s why we put all of our temperature sensors, as well as those of our competitors, through rigorous, real-world testing—to relentlessly pursue the excellence you demand.

If there’s a risk to take, we take it for you. If there’s an opportunity to pursue, we pursue it for you. If there’s a problem to solve, we solve it for you.

This is performance beyond product.
