What Qsenz does

Qsenz B.V. is a Netherlands-based B2B supplier and system integrator of water and gas quality analysis equipment, founded in 2015 and headquartered in Den Burg with a second office in Maurik. The company delivers, installs, and maintains measurement solutions for industrial companies, municipal wastewater treatment plants, drinking water utilities, and government bodies, with a documented focus on the wastewater value chain. Its operating model combines representation of multiple major instrumentation manufacturers (Badger Meter Austria/s::can, Badger Meter UK/ATI, 3S-analysers, Cerlic, SOLiSENZ) with proprietary in-house developed products including the Analytical Filtration System (AFS) Filterunit, the patented Smart Cleaner automatic optical-sensor cleaning system, and the SOLiSENZ CSZ TSS measurement system for centrate. The underlying technology stack spans in-situ UV-Vis spectrophotometry, amperometric sensors, ion-selective membrane electrodes, optical sensors, and microwave-based measurement, supported by signal amplifiers, interface modules, and s::can software tools (moni::tool, Vali::tool, Ana::tool, Io::tool, Visu::tool). Qsenz generates revenue through hardware sales of sensors, analyzers, and complete measurement systems, complemented by recurring service visits, maintenance contracts, and telemetry monitoring. Go-to-market is sales-led and direct, with customers requesting quotes via the company website, phone, and email. The company employs 1–10 people and operates entirely within the Netherlands, with no disclosed external funding or institutional investors.
