What Kinds of Products and Instruments Does Ott Offer?

Ott offers four main product categories for water and environmental monitoring: dataloggers and telemetry devices (such as the XLink 2000), water level and pressure level sensors (such as the Ott PLS 500), hydrology analytics software (such as OTT HydroSight), and a broader range of water quality and meteorological sensors. These products are designed to work together as connected monitoring networks rather than as standalone instruments, so the right fit depends on whether you need a single sensor, a full telemetry setup, or software to turn field data into decisions.

Dataloggers and Telemetry: The Connectivity Layer

The XLink 2000 is Ott's flagship datalogger, positioned for hydrological, environmental, and urban monitoring applications. According to Ott, it combines advanced connectivity, strong cybersecurity, and a future-ready architecture intended to help organizations build resilient monitoring networks. A US version is listed as the XLink2000-US-0-0.

This category matters if your priority is getting field measurements reliably into a connected workflow—for example, linking multiple sensors across a watershed and transmitting data securely. If you only need a single local reading, a datalogger may be more infrastructure than the task requires.

Water Level and Pressure Sensors

The Ott PLS 500 is a pressure level sensor offered in a Modbus, metric configuration with a 0–10 m range (listed as 6303900190-M-M-1). It falls under Ott's water quantity line, which covers water level and flow monitoring from streams to reservoirs, providing real-time data for resource management, flood prediction, and ecosystem support.

Choose this category when your core measurement is water level or pressure head in a defined range. The 0–10 m range is a concrete selection condition: sites with greater depth or different output requirements would need to check other configurations rather than assume this model fits.

Hydrology Analytics Software

OTT HydroSight (listed as 2250000190) represents the software side of the portfolio. Ott frames its overall offering as "hydrology analytics"—sensors plus accurate data plus connected workflows—with the stated goal of giving water managers "decision-ready intelligence." The software layer is what converts raw instrument readings into something usable for planning and reporting.

This is relevant if you already collect data but struggle to analyze it consistently. It is less relevant if you have no instrumentation yet, since analytics depends on a data source.

Water Quality and Meteorology Instruments

Beyond level and flow, Ott's instruments cover:

• Water quality: temperature, pH, turbidity, and other key indicators, aimed at better decision-making.
• Meteorology: sensors measuring precipitation amount and intensity, used for weather observation, flood warning, and resource planning.

For solar radiation and atmospheric monitoring specifically, Ott directs visitors to its Kipp & Zonen brand at kippzonen.com—a useful routing detail if your interest is radiation rather than water.

How the Brands Fit Together

Ott's portfolio includes several long-established brands, which helps explain the breadth of products:

If you encounter Sutron or In-Situ products while researching Ott, they are part of the same family rather than competitors.

Choosing Based on Your Monitoring Task

A practical way to decide:

• Need to modernize or network existing sensors? Start with the XLink 2000 datalogger.
• Need direct water level measurement in a moderate range? Look at the PLS 500 and confirm the range and Modbus output match your site.
• Need water quality indicators? Ott's water quality instruments cover temperature, pH, turbidity, and similar parameters.
• Need precipitation data? The meteorology sensor line covers amount and intensity.
• Need to analyze data you already have? OTT HydroSight is the analytics entry point.
• Need solar radiation data? Go to Kipp & Zonen instead.

One caveat: the available product pages list model numbers and descriptions but do not publish prices, so budgeting requires contacting Ott directly rather than assuming listed items are freely accessible or priced online. For current specifications and configuration options, the individual product pages ("View Product") are the authoritative source.
