What Lakewood Instruments does
Lakewood Instruments is a privately held industrial water treatment equipment manufacturer founded in 1973 and headquartered in Milwaukee, Wisconsin. The company designs and manufactures controllers, sensors, and accessories that automate chemical dosing and monitor water quality parameters (pH, ORP, conductivity, trace chemistry) in cooling towers, boilers, and process water applications for commercial and industrial facilities. Its core product line includes the NexSys controller (which integrates with building management systems via LON, BACnet, and MODbus protocols), the Model 3175e/1575e/140/150 series controllers, the Little Dipper 2 Fluorometer (OEM-supplied by Turner Designs), and a full range of pH, ORP, and conductivity sensors. The company emphasizes product longevity, reporting that controllers remain operational in the field for 15-25+ years, and operational performance with 95% of products shipping within two days of order placement.
The company operates a sales-led go-to-market model with multiple order channels (phone, fax, email, online order form, mail) and quote-based pricing for all products. Distribution is primarily direct to end customers and through a partner network of water treatment service companies and chemical providers who resell and specify Lakewood equipment. The company is owned by Bill Brink, who also owns ETI (Electronic Technologies Inc.), the manufacturer of Lakewood's circuit board components, providing vertical integration for electronic components. Revenue is generated entirely through hardware sales — controllers, sensors, fluorometers, and parts/accessories — with no software subscription or recurring service revenue model evident. The company remains a domestic, single-country operator with no disclosed international expansion or institutional investment.
