In-Situ Process products

RDO Blue uses In-Situ’s patented Optical Rugged Dissolved Oxygen technology, an EPA-approved dissolved oxygen measurement method ideal for measuring DO and temperature in even the harshest environments. Suitable for handheld use or long-term deployment in fresh water or saltwater, this low-maintenance dissolved oxygen probe offers robust performance at a lower cost than other DO meters.

The RDO PRO-X Dissolved Oxygen Probe uses optical technology (EPA-approved RDO technology for Clean Water Act programs) to measure dissolved oxygen and temperature in demanding process environments. This durable probe requires no calibration or conditioning prior to deployment and does not use membranes. The replaceable RDO Smart Sensor Cap stores calibration coefficients for automatic, error-free setup.

This reliable, all-in-one instrument, measures and records water level and pressure, conductivity and temperature. This sensor is available in vented and non-vented configurations, features a unique conductivity cell design that allows for a wide accurate-measurement range in a narrow diameter instrument. Titanium construction resists corrosion and sub-1-inch design fits narrow-diameter wells, making the Aqua TROLL 200 Data Logger ideal for coastal, remediation and mine-water monitoring projects.

The Aqua TROLL 100 Data Logger measures and records conductivity and temperature. A unique conductivity cell design allows for a wide, accurate measurement range in a narrow diameter instrument. Titanium construction resists corrosion, making the Aqua TROLL 100 Data Logger ideal for coastal, remediation and mine water monitoring projects. Deploy the Aqua TROLL 100 in depths up to 300 psi.

The Aqua TROLL 800 fully customizable, seven-port multiparameter sonde, with capacity for six interchangeable sensors and an antifouling wiper, is ideal for short-term or long-term deployments in fresh water or saltwater, surface water or groundwater. The Aqua TROLL 800 features long-lasting battery power and a smartphone interface that enables simplified calibration, live time-series data view and report creation. Vented and non-vented pressure sensor options available.

The Aqua TROLL 700 is a fully customizable, seven-port multiparameter sonde with capacity for six interchangeable sensors and an antifouling wiper. It offers the flexibility, reliability and ruggedness required for spot checking, remote monitoring, and long-term monitoring in surface water, coastal and groundwater applications. A smartphone interface delivers accurate data and enables simplified calibration, live time-series data view and report creation.

The Aqua TROLL 600 is a fully customizable five-port multiparameter sonde with capacity for four interchangeable sensors and an antifouling wiper. A smartphone interface delivers accurate data and enables simplified calibration, panoramic data view and report creation. Ideal for short-term and long-term deployment. Available in vented and non-vented options.

The Aqua TROLL 500 is a fully customizable five-port multiparameter sonde with capacity for four interchangeable sensors and an antifouling wiper. A smartphone interface delivers accurate data and enables simplified calibration, panoramic data view and report creation. Ideal for spot-checking and profiling applications when used with a Wireless TROLL Com or long-term monitoring with VuLink.

Rugged and compact, the Aqua TROLL 400 can be deployed for months of unattended operation in harsh field conditions. And because it’s easy to install and maintain, you save on training and reduced trips to the field. Open communication protocols easily interface with your existing telemetry system. Access data anytime with a radio, controller, data logger, sampler, telemetry system, SCADA/PLC system, or HydroVu Data Services.

The rugged dissolved oxygen (RDO) RDOX probe, with its proprietary membrane protection layer, is the most abrasion-resistant optical DO probe available for measuring dissolved oxygen (DO) in demanding wastewater process environments. A machined stainless steel body option is available for added confidence in the harshest environments. The RDO EPA Approved Method allows NPDES permit holders to monitor influent, effluent and treatment processes. The RDOX probe is immediately auto calibrated upon cap installation for ease of use and high accuracy.
