About SWAN
SWAN Analytische Instrumente AG develops and produces highly precise online measurement instruments for water quality. The range comprises more than 490 products: analyzers for conductivity, dissolved oxygen, pH/redox, sodium, silica, chlorine, phosphate, hydrazine, TOC and turbidity, as well as associated transmitters and photometric field devices (Chematest). Production takes place exclusively at the Swiss headquarters in Hinwil using lean, make-to-order processes, including in-house sensor production, factory calibration and final inspection; all instruments are delivered as configured plug-and-play units. Through SWAN Systeme AG, the group also supplies sampling and analysis systems (SWAS) as a turnkey solution, from concept through assembly to commissioning. Customers come from power generation, industry, drinking and wastewater, pharmaceuticals, semiconductors, leisure pools, Food & Beverage and green hydrogen. SWAN is represented worldwide with 14 subsidiaries and employs more than 350 staff.
