We Understand What It's Like To Deal With Unresponsive Suppliers

At Wasco, we know that you want to feel confident in the specification and delivery of your pressure sensors. In order to feel confident, you need a communicative and responsive supplier. Most companies don't take the time to communicate clearly, but we believe that specifying a pressure sensor shouldn't be stressful. Since 1989, we've specified over 6000 unique pressure sensors, and we have a dedicated team to provide you with all the information you need along the way.

We design and manufacture our products for ultra high purity and highly corrosive environments found in next-generation semiconductor processing equipment. Rated for millions of cycles, our sensors have materials available that meet or exceed SEMI F20 (UHP) with a critical pitting temperature performance of > 35ºC. All switches are helium leak tested to ≤ 1 x 10^(-9) std cc/sec Helium (per SEMI F1). 5Ra internal surface finish. Multiple fittings, connections, and customizable options are available.
