What In-Situ does
In-Situ Inc. is a Fort Collins, Colorado-based designer and manufacturer of water monitoring instrumentation serving environmental, municipal, agricultural, aquaculture, mining, and industrial customers globally. The company's product portfolio spans multiparameter water quality sondes (Aqua TROLL 400-800 series), water level data loggers (Level TROLL 100-500 and Level TROLL NC non-contact radar), optical dissolved oxygen sensors (RDO Blue, RDO Trio), UV-series process analyzers (ChemScan), Doppler ultrasonic flow meters (AgriFlo XCi, HydroMace XCi, MACE and Partech lines), and supporting accessories. Hardware is integrated with VuLink cellular telemetry, the VuSitu mobile application for Bluetooth-based field configuration, and the HydroVu cloud-based data services platform, which provides network-wide visibility, alarms, and a public API for third-party data access.
In-Situ generates revenue through a mix of hardware sales, software subscriptions (HydroVu), equipment rentals (Ajax Rentals division), and service/maintenance contracts (In-Situ Care plans). Pricing is quote-based and not publicly disclosed. The company sells via direct sales and an e-commerce storefront, complemented by an Ajax Rentals fleet spanning five U.S. warehouses and channel partnerships including an exclusive ecoTech distribution arrangement for Germany. Service centers operate in Fort Collins, Redditch and St Austell (UK), and Sydney (MACE Australia), supporting customers across North America, Europe, the Middle East, Africa, Asia-Pacific, and Latin America.
The company operates through five wholly-owned subsidiaries — In-Situ Europe Ltd., Partech (flow), MACE (flow), ChemScan (analyzers), and Ajax Rentals — and maintains a portfolio of sub-brands including Aqua TROLL, Level TROLL, Rugged TROLL, RDO, VuLink, VuSitu, HydroVu, and AquaPod. In November 2025, In-Situ signed an agreement to be acquired by Veralto (NYSE: VLTO), with the deal completing in January 2026; In-Situ now operates within Veralto's OTT HydroMet operating company. Public revenue figures are not disclosed.
