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.

Core offering

In-Situ designs, manufactures, and sells water monitoring instrumentation including multiparameter sondes (Aqua TROLL series), water level data loggers (Level TROLL series), dissolved oxygen sensors (RDO series), flow meters, and process analyzers (ChemScan). The hardware is integrated with VuLink cellular telemetry, HydroVu cloud data services, and the VuSitu mobile application for real-time remote water quality, level, and flow monitoring across groundwater, surface water, drinking water, wastewater, aquaculture, mining, and coastal applications.

Product overview

In-Situ offers a comprehensive water monitoring portfolio combining instrumentation hardware with software and data services. The core product lines include multiparameter sondes (Aqua TROLL series: 400, 500, 600, 700, 800) for water quality measurement, Level TROLL data loggers (100, 200, 400, 500, NC) for water level monitoring, and RDO dissolved oxygen sensors (RDO BLUE, RDO Trio). These connect via VuLink telemetry to the HydroVu cloud-based data platform and VuSitu mobile app. The company also offers flow monitoring solutions through its Mace/Partech brands including AgriFlo XCi meters and Doppler sensors. Process analyzers under the ChemScan brand provide drinking water and wastewater monitoring. The portfolio integrates hardware sensors with software platforms for real-time decision-quality data collection and analysis.
