Annual sensor production now exceeds 1 million pieces. Doing business with Keller is easy and most inquiries are answered within 24 hours. Standard delivery on U.S.-assembled products is 3 days ARO. They offer convenient terms with approved credit and accept most major credit cards. At Keller, providing customers with superior value is a way of life.
