Home Products Catalogs Order More Semiconductor Since 1987, Wasco has been supplying the semiconductor market with Ultra High Purity (UHP) sensing solutions. Our customers use our UHP products in wafer fabrication equipment (gas boxes, gas sticks, chamber pressure) and facilities equipment (gas cabinets, gas panels). Wasco is ISO 9001:2015 certified, and our products are both UL recognized and CE compliant. Together, our team has over 100 years of combined experience in providing sensing solutions to the semiconductor market. We engineer, manufacture, and sell pressure switches that are temperature resistant, reliable, robust, and cost-effective. 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. Most companies don’t take the time to understand the complexity of your system. 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 fire suppression industry since 1995. Contact us today to stop wasting time and money, and instead get exactly what you need, precisely when you need it. 1. Tell us what you need 2. Review the specifications 3. Place an order Get A Quote FEATURES We design and manufacture our sensors 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, transducers, and gauges 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.
