At Wasco, we know that you want to feel confident in the specification process. To do that, you need a pressure sensor that meets your requirements. The problem is that most companies don’t take the time to understand the complexity of your requirements.

We believe it shouldn’t be so difficult. We understand how complicated the specifying process is because we’ve specified and sold hundreds of thousands of pressure sensors for customers in the defense market since 1987.
