Proteus Industries Inc.

Proteus Industries is dedicated to developing high quality and innovative flow management products and providing consistent customer satisfaction.

Proteus Industries was founded by Jon Heiner in 1978. Starting his career in the semiconductor equipment industry and recognizing the need for reliable flow switch, he developed Proteus’ first flow switch, model 100B, and acquired his first customer, Varian.

Starting his flow technology venture in his parents’ basement, he began to expand and started developing, manufacturing, and marketing a range of rugged yet sensitive liquid flow switches, meters, and sensors.

Proteus offers a full line of instruments and control solutions for the semiconductor and fab equipment industry. Today, our products are used in virtually every semiconductor fab around the world.
