Moeller Instrument

What Moeller Instrument does

Moeller Instrument Company, Inc. is a privately held U.S. specialty manufacturer of precision temperature and pressure measurement instruments, headquartered at 1225 Pearl Street, Waukesha, Wisconsin, with a secondary contact line suggesting a Connecticut presence. The company has operated continuously under the Moeller name since 1867, building a catalog of bimetallic dial thermometers, gas-actuated remote-reading dial thermometers, Bourdon-tube pressure gauges in bronze, stainless steel, monel and alloy-steel constructions, industrial liquid-in-glass thermometers, and marine clinometers/trim indicators. Its technical differentiation rests on low-mass single-coil bimetallic helix construction with silicone damping (1% full-scale accuracy, all 300-series stainless), gas-actuated systems with up to 125 feet of armored stainless capillary, solid-front/blow-out-back safety pressure gauges, and a Duo-Temp dual-element configuration combining a bimetallic sensor with an RTD or thermocouple in a single thermowell.

The commercial model is direct, specification-driven sales: customers contact the company via toll-free phone or website form, specify parameters (dial size, case material, connection type, range, insertion length, capillary length, Bourdon/socket material, accuracy), and receive a custom quote. Pricing is not publicly disclosed. Customers are organized into three verticals — industrial/commercial process measurement, marine (including vessel trim/angle instruments), and military (MIL-I-17244E, MIL-T-19646, MIL-G-18997E, and CID-A-A-59308 qualified instruments) — with the military segment flagged as primary in the source data. Headcount is reported at 11-50 employees, and there is no disclosed distribution, third-party reseller, or marketing channel beyond the company website. No funding rounds, M&A, leadership changes, partnership announcements, or geographic expansions appear in the source material, and the company shows no AI/ML capability, mobile app, public API, or social media presence.

Core offering

Moeller Instrument Company manufactures custom-specified precision temperature and pressure measurement instruments, including bimetallic dial thermometers, gas-actuated remote reading thermometers, Bourdon tube pressure gauges, industrial liquid-in-glass thermometers, marine clinometers, and dual-element Duo-Temp thermometers, with a dedicated line built to MIL specifications for shock and vibration resistance. Products are sold primarily through direct contact (toll-free phone, local phone, website specification/contact forms) and made-to-order in 300-series stainless steel and other alloys for industrial, commercial, marine, and military applications.

Product overview

Moeller Instrument Company, Inc. manufactures a comprehensive portfolio of temperature and pressure measurement instruments, established in 1867. The product line centers on four core instrument families: Bimet Thermometers (dial-type with BIMET helix technology), Gas Actuated Dial Thermometers (remote reading with gas-filled sensing elements), Pressure Gauges (Bourdon tube-based instruments in multiple accuracy grades), and Industrial Liquid In-Glass Thermometers (spirit-filled instruments with adjustable angle design). Supporting products include Marine Instruments/Clinometers for vessel trim measurement and Duo-Temp Remote Reading Thermometers combining local dial and remote RTD sensing in a single thermowell. The company also produces a dedicated Military product line meeting MIL specifications (MIL-I-17244E, MIL-T-19646, MIL-G-18997E, CID-A-A-59308) for defense and marine applications. Thermowells and ordering forms complete the product ecosystem, enabling customers to specify complete measurement solutions for industrial, commercial, and military applications.
