Facilitating Wastewater Plant Efficiency with OTEK Meters

01. Obsolescence Hardened

Obsolescence is best managed when considered at the start of a design. OTEK's patented technology is the result of forward-thinking decades from now. Our instruments built in 1974 still work in facilities today. That's obsolescence hardened!

02. Plug & Play

OTEK provides 100% form, fit, and function obsolescence upgrades for a variety of decommissioned bargraph meters, digital panel meters, controllers, batch counters, process loggers, and bargraph indicators. We work hard so you can Plug & Play!

03. Lifetime Warranty

We design, develop, and manufacture our products in the U.S., deploying state-of-the-art technology and using only the highest quality materials and components. Our proven excellence delivers an unprecedented lifetime warranty.
