SolidSense II® Pressure Transducers

Maximize process precision with accurate, stable, ultra-high purity control.
Models GF / GI

For measuring pressure in ultra-high purity and specialty gas applications across many industries, pressure transducers must maintain stability and accuracy. That's why Brooks Instrument SolidSense II® pressure transducers combine weld-free, corrosion-resistant materials along with design that delivers outstanding zero stability and accuracy within 0.25% of full scale.

We avoid the problems of zero and span drift, thermal shift and case stress that lead to maintenance and downtime issues with competitive transducers. Instead, SolidSense II® instruments deliver a robust, easy-to-maintain design that lowers the total cost of ownership.
