OTEK Corp

What OTEK Corp does

OTEK Corporation (founded 1972 as IMC, rebranded 1988) is a privately held Tucson, Arizona-based designer and manufacturer of high-reliability LED panel meters, bar graph meters, and process control instruments. The company sells directly to industrial customers across nuclear, military, aerospace, medical, energy/utilities, and general industrial verticals, with a US-government CAGE CODE (57861) and a track record including NASA Apollo Project contributions and Space Shuttle program qualified products. Its core technology platform centers on Powerless (loop-powered) operation—as low as 6mW—built on >12 patents and pending patents, with an obsolescence-hardened design using generic multisource components rated for >40 years CMTBF and warranted for life.

The product portfolio is organized around four core families: the PNP (Plug N Play) series, which is a cyber-security-exempt hardware-only design with no microprocessor that replaces 100% of legacy analog meters in existing cutouts; the NTM (New Technology Meter) series featuring automatic tricolor bargraph displays and math/PID functions; the UPM (Universal Panel Meter/Counter) supporting over 20 analog signals; and the HIQ (High Intelligence Meter) with isolated I/O and relay outputs. Supporting products include the PLCT transmitter, SRD serial remote display, TLD triple-loop display, LPI loop-powered isolator, and the ACS analog-to-digital converter family. All products are available in Mil-Spec, Class 1E nuclear, I.S. (Intrinsically Safe), and industrial grades, with over 80 plug-in signal conditioning modules enabling one mainframe to replace 200+ legacy models.

OTEK generates revenue through direct hardware sales (quote-based, configured-to-order) from its Tucson headquarters via phone, email, and proprietary online P/N and Price Configurators that allow global customers to specify and price products 24/7. There are no disclosed resellers or distribution partners, no public list prices, no app, no API, and no external funding rounds; the company appears to be independently owned and operated. A single disclosed leader, Otto Fest (President), leads an organization of 11-50 employees.

Core offering

OTEK Corp designs and manufactures LED panel meters, bargraph meters, and process control instruments organized around four core product families — PNP (Plug N Play), NTM (New Technology Meter), UPM (Universal Panel Meter/Counter), and HIQ (High Intelligence Meter) — plus the PLCT transmitter, signal conditioners, displays, and custom-engineered solutions. The company's products are built around proprietary powerless (4-20mA loop-powered) technology and a modular plug-and-play system with more than 80 interchangeable input/output modules, targeting military, nuclear, energy, aerospace, medical, and industrial customers requiring high-reliability, long-lifecycle instrumentation.

Product overview

OTEK Corp manufactures LED panel meters, bar graph meters, and process control instruments. The product portfolio is organized around four core product lines: (1) PNP (Plug N Play) - cyber security exempt meters with no microprocessor that replace 100% of existing analog meters using existing cutouts and wiring; (2) NTM (New Technology Meter) - smart microprocessor-based meters with automatic tricolor bargraphs, math functions, and isolated I/O; (3) UPM (Universal Panel Meter/Counter) - universal meters supporting over 20 analog signals with counter, timer, and clock functions; and (4) HIQ (High Intelligence Meter) - high-end intelligent meters with isolated I/O and relay outputs. The company also offers the PLCT (Programmable Logic Controller Transmitter), legacy MATURE products for backward compatibility, and discontinued EVOLUTION products with replacement guidance. Supporting accessories include the SRD Serial Remote Display, TLD Triple Loop Display, LPI Loop Powered Isolator, LPB Loop Powered Bargraph, BDM Bus Display with USB/RS232/RS485/Ethernet, and the comprehensive ACS series of analog-to-digital converters. Products are available in Mil-Spec, Class1E, Nuclear, I.S. (Intrinsically Safe), and Industrial grades, with plug-in signal conditioning modules supporting current loop (4-20mA, 10-50mA), VAC/DC, WAC/DC, AAC, and Hz inputs.
