What Hydrolab does

Hydrolab provides multiparameter instruments and software applications for water quality monitoring. The product portfolio spans water level sensors (pressure, bubble, radar, and camera-based technologies), flow and discharge measurement systems (wading rods, stationary, and mobile), water quality instruments (multiparameter sondes and single parameter instruments), meteorological sensors (precipitation, temperature/humidity, disdrometers, soil moisture), dataloggers, telemetry systems, and supporting software. The company traces heritage to 1873 through the Ott brand and operates within a multi-brand portfolio that includes Sutron (data-collection and telemetry, established 1975) and In-Situ (water quality and level monitoring, joined 2026). Hydrolab is part of Veralto's Water Quality platform alongside brands such as Hach, ChemTreat, McCrometer, Sea-Bird Scientific, Trojan Technologies, and XOS, with legal entity OTT HydroMet GmbH domiciled in Germany and US operations managed from Sterling, Virginia.

The business operates through three revenue streams: hardware instrumentation sales (sensors, level sensors, flow measurement devices, accessories, and meteorological instruments), professional services (installation, maintenance, calibration, repair, and rentals), and software/firmware subscriptions. Pricing is quote-based with no publicly listed standard tiers, and rental options are available. Go-to-market is enterprise field sales with regional sales contacts targeting government agencies at the federal, state, and local level (supported by a GSA marketplace listing), environmental consulting and engineering firms, and research institutions. The company participates in major industry events including Singapore Water Week, AWWA ACE, IWA World Water Congress, AGU Annual Meeting, AMS Annual Meeting, IAH World Groundwater Congress, and StormCon, and uses content marketing (knowledge center, case studies, technical documentation) to support technical evaluation and procurement decisions.

Recent strategic activity reflects platform consolidation under Veralto: in 2024 OTT HydroMet was split into Ott and Kipp & Zonen to sharpen each brand's specialization, and in 2026 In-Situ was integrated into the Ott portfolio to expand field and environmental monitoring capabilities. Product investment has emphasized new measurement modalities, including OTT HydroSight (contactless flow monitoring using video analytics) and the Ott CBS 500 bubble sensor for water level monitoring, supporting the company's positioning as a provider of decision-ready intelligence for water resource management.

Broad incumbents

• Xylem: Xylem is a broad water technology incumbent offering smart metering, network monitoring, and analytics for water utilities. Its SonTek and YSI brands overlap directly with Ott's flow and water quality instrumentation, while Xylem's larger scale and SaaS analytics platform give it broader market reach.
• Endress+Hauser: Endress+Hauser is a global leader in industrial process instrumentation including flow, level, and water quality measurement. While focused on industrial process customers, its level and flow product lines overlap with Ott's hydrology sensors for utility and environmental applications.
• KROHNE: KROHNE is an established European industrial instrumentation manufacturer with strong flow and level measurement product lines serving water/wastewater, chemical, and process industries. Its level and flow products compete with Ott's sensor portfolio in industrial and municipal applications.
• Yokogawa Electric: Yokogawa supplies industrial process analyzers and flowmeters used in water/wastewater and power plant applications. Its analyzer portfolio competes with Ott's quality instrumentation in industrial and municipal water monitoring contexts.

Direct peers

• Hach: Hach is a direct peer in water quality analytical instruments (multiparameter sondes, lab and process analyzers). Notably, Hach is also a sister company under Veralto's Water Quality platform, making the relationship both competitive and collaborative — they share end customers (water utilities, government, industry) and overlapping product lines.
• In-Situ: In-Situ makes water-quality and water-level monitoring instruments for environmental professionals and was acquired into the Ott family in 2026. Its Aqua TROLL, Level TROLL, and RDO products overlap directly with Ott's multiparameter sondes and level sensors, making it a peer by product even after integration.
• McCrometer: McCrometer is a Veralto sister brand manufacturing flow meters (propeller, electromagnetic, differential pressure) for irrigation, municipal, and industrial water applications. Its flow measurement portfolio directly overlaps with Ott's discharge measurement products.
• Teledyne Technologies (Teledyne RD Instruments, ISCO): Teledyne's environmental instrumentation businesses (including ISCO for water quality and flow sampling, and Teledyne RDI for acoustic flow) directly compete with Ott's water quality and discharge measurement products. Both serve government, research, and municipal customers with comparable hydrology instrumentation.
• Sea-Bird Scientific: Sea-Bird Scientific is a sister company under Veralto specializing in oceanographic and water quality sensors (CTD profilers, underway systems). It overlaps with Ott in environmental monitoring and shares the Veralto parent, while competing on adjacent oceanographic and research customers.

Emerging players

• AquaRead (Aquaread): Aquaread is a smaller specialist in multiparameter water quality sondes and handheld instruments for environmental and field monitoring. It overlaps with Ott's water quality portfolio but at a smaller scale and with a more field-portable product focus.
