Miljoco

What Miljoco does

Miljoco Corporation is a US-based manufacturer of temperature and pressure measurement instruments, founded in 1979 in Michigan by Howard M. Trerice and now led in its second generation by Howard O. Trerice (President since 2009). The company designs and produces industrial, bimetal, vapor-actuated, drum, and digital thermometers alongside commercial, industrial, and specialty pressure gauges, plus accessories such as thermowells, syphons, snubbers, diaphragm seals, ball valves, needle valves, and test plugs. A wholly-owned Chinese manufacturing subsidiary, Miljoco China Precision (established 1999), supports global production, and the corporate headquarters and main manufacturing operations are housed in a four-times-larger renovated facility in Mt. Clemens, Michigan occupied since 2011.

The company's competitive position rests on regulatory certifications and category leadership: it is described as one of the largest manufacturers of NSF-listed vapor-actuated dial thermometers for the commercial foodservice industry, the leading supplier to the fire suppression industry since 2003, and a producer of lead-free pressure gauges and thermometers certified to NSF/ANSI Standards 61 and 372 for potable and drinking water safety. Products are sold B2B exclusively through a global distribution network to equipment manufacturers, mechanical contractors, and maintenance personnel; pricing is quote-based rather than publicly disclosed, and there is no direct e-commerce channel.

Revenue mechanics center on three primary hardware revenue streams — temperature instruments, pressure instruments, and accessories — across four customer verticals: food service OEMs, fire suppression, commercial HVAC, and broader industrial instrumentation. The company is privately held by the founding Trerice family, with no disclosed institutional investors, funding rounds, or M&A history. A 2024 website footer identifying the operating entity as "Miljoco-Weiss, LLC" and Terms & Conditions of Sale hosted on assets.omega.com indicate a recent corporate restructuring and apparent affiliation with DwyerOmega, though details of that arrangement are not disclosed.

Broad incumbents

• DwyerOmega: DwyerOmega is a large, broad-line manufacturer of measurement and process instrumentation including pressure gauges, thermometers, and process controls. Miljoco's website currently uses DwyerOmega's Terms and Conditions of Sale and a DwyerOmega-branded logo header, suggesting a distribution, branding, or ownership relationship. Highly comparable on product lines (pressure gauges, thermometers) and on serving HVAC, foodservice, and industrial OEM channels.
• Watts Water Technologies: Watts Water manufactures pressure and temperature regulation products for plumbing, water quality, and HVAC applications, including lead-free certified components for potable water. Comparable as a broad incumbent serving potable water and HVAC contractors, the same channels where Miljoco's lead-free and NSF-certified gauges are specified.
• WIKA Alexander Wiegand SE & Co. KG: WIKA is a global leader in pressure, temperature, level, and flow measurement instrumentation, including mechanical and digital gauges and thermometers. Comparable as a broad incumbent pressure and temperature instrument manufacturer serving industrial, HVAC, foodservice, and process customers worldwide.
• JUMO Instrument Co. JUMO is a global German-based manufacturer of temperature, pressure, and analytical measurement instrumentation with strong presence in HVAC, food and beverage, and water/wastewater.
