Whether you are monitoring water quality in surface water, coastal, or groundwater environments, or in drinking water or wastewater applications, you can rely on our robust instruments to accurately collect data. Our single-parameter and multi-parameter water quality instruments are designed for spot-checking or continuous and remote water quality monitoring. They are easy to use and maintain, delivering long-lasting performance even in harsh conditions.
Multiparameter Water Quality Instrument Aqua TROLL 700
Aqua TROLL 700 is a fully customizable seven-port multi-parameter sonde accommodating six interchangeable sensors and an anti-fouling wiper. It offers the flexibility, reliability, and ruggedness required for spot-checking, remote monitoring, and long-term deployments in surface water, coastal, and groundwater applications. Its smartphone interface delivers accurate data and simplifies calibration, real-time time-series data viewing, and report generation.
Utilize the Aqua TROLL 700 with the wireless TROLL Com and VuSitu mobile application for spot-checking and profiling applications, and with VuLink telemetry and HydroVu data services for long-term monitoring. Interlocking mechanisms, Rapid Response sensors, an onboard mini calibration cup, and built-in safeguards streamline setup and deployment. Active and passive anti-fouling features extend maintenance intervals. Options include vented and non-vented pressure sensors.
Sensor options include: Temperature, Conductivity, pH/ORP, Rugged Dissolved Oxygen (RDO®), Turbidity, Chlorophyll a, Phycocyanin (BGA-PC), Phycoerythrin (BGA-PE), Fluorescent Dissolved Organic Matter (FDOM), Crude Oil, Rhodamine WT, Fluorescein WT, Ammonium (ISE), Chloride (ISE), and Nitrate (ISE).
Multiparameter Water Quality Instrument Aqua TROLL 500
Aqua TROLL 500 is a fully customizable multi-parameter sonde featuring interchangeable sensors and a smartphone interface that delivers accurate data while simplifying calibration, panoramic data viewing, and report generation. Ideal for spot-checking and profiling applications when used with Wireless TROLL Com or for long-term monitoring with VuLink telemetry. The Aqua TROLL 500 provides the flexibility, reliability, and durability required for spot-checking, low-flow sampling, remote monitoring, and long-term water or stormwater monitoring. Its corrosion-resistant titanium construction withstands harsh environments, and the convenient LCD display for sensor health and connectivity readings ensures deployment confidence.
Sensor options include: Temperature, Conductivity, pH/ORP, Rugged Dissolved Oxygen (RDO®) handheld monitor, Turbidity, Chlorophyll a, Phycocyanin (BGA-PC), Phycoerythrin (BGA-PE), FDOM, Crude Oil, Rhodamine WT, Fluorescein WT, Ammonium (ISE), Chloride (ISE), and Nitrate (ISE).
In-Situ Rugged Buoy
In-Situ Rugged Buoy is a reliable, cost-effective monitoring platform for long-term instrument deployment and telemetry in ponds, lakes, estuaries, rivers, and coastal nearshore environments. Its saltwater-tolerant construction and UV-resistant materials endure harsh conditions, while the self-righting feature protects deployed equipment and ensures continuous data collection.
With adjustable deployment depths from 0.3m to 1.0m in 5cm (2-inch) increments, users can customize deployment depth and collect multi-depth data from a single platform. The adjustable-depth well is load-bearing, enabling anchor systems to attach to the buoy’s low point. For deeper monitoring, instruments can be suspended from mooring lines with cables connected to telemetry devices within the buoy.
The fully assembled Rugged Buoy is ready to deploy out of the box, facilitating easy transport and deployment. Foam-filled flotation is faceted to prevent rolling during transport or when on its side. Weighing only 16kg (35 lbs), the buoy meets standard freight dimensions and weight limits. Integrated carrying straps allow single-technician handling for loading, lifting, lowering, and retrieval.
The buoy is designed to house In-Situ multi-parameter instruments and telemetry for low-maintenance deployments. VuLink long-life batteries and the Aqua TROLL sonde’s robust anti-fouling capabilities reduce site visits. The Rugged Buoy simplifies setup and data management through compatibility with all instruments, software, and accessories within the In-Situ ecosystem.
Water Level Tape and Water Level Meter
Ensuring the longest service life under field use conditions,The Water Level Meter 200 is equipped with a high-strength steel tape and stainless steel conductors, suitable for measuring water depth in wells, boreholes, direct-push equipment, and standpipes.
The yellow tape is highly visible and resistant to stretching under a load of 127 kg (280 lbs), ensuring higher accuracy. It allows for reading static water level measurements and can be easily switched to drawdown mode for low-flow testing and pump tests. Additionally, the probe, with an IP68 protection rating, can be submerged in wells deeper than 300 m (1000 ft) to determine the bottom of the well.
RDO PRO-X Dissolved Oxygen Sensor
The RDO PRO-X Dissolved Oxygen Sensor utilizes optical technology (EPA-approved RDO technology) to measure dissolved oxygen and temperature in industrial environments. The sensor requires no calibration before use and does not use sensor membranes. The replaceable RDO smart sensor cap stores calibration coefficients for automatic and error-free setup.
With flexible communication protocols (4–20 mA, Modbus/RS485, or SDI-12), it is easy to integrate with PLC systems, telemetry systems, or HydroVu data services, enabling real-time feedback within the system.
With the RDO PRO-X, holders of U.S. National Pollutant Discharge Elimination System (NPDES) permits can monitor influent, effluent, and treatment processes, and respond quickly to changes in oxygen and temperature, thereby achieving more precise and efficient process control.
