The SonTek 10-MHz ADV (Acoustic Doppler Velocimeter) is a proven, accurate solution for high-precision, 3-axis (3D), velocity measurements in a wide variety of settings from the laboratory to the ocean. ADV performance has been shown to compare favorably with laser Doppler systems costing ten times as much. In addition, the ADV is extremely simple to set up and use. Most users are taking high quality data within minutes of receiving the system.

The SonTek 16-MHz MicroADV (Acoustic Doppler Velocimeter) is the most significant breakthrough in 3-axis (3D) current meter technology since the original SonTek ADV. The original SonTek ADV has compared favorably with Laser systems costing ten times as much — the MicroADV fares even better. The higher acoustical frequency of 16 MHz makes the MicroADV the optimal instrument for laboratory work. Like all SonTek instruments, the MicroADV is extremely simple to set up and use. Most users are taking high-quality data within minutes of receiving the system.

The SonTek ADP (Acoustic Doppler Profiler) is a high-performance, 3-axis (3D) water current profiler that is accurate, reliable, and easy to use. The ADP uses state-of-the-art transducers and electronics designed to reduce side-lobe interference problems that plague other current profilers. This allows the ADP to make the very near-boundary (surface or bottom) current measurements critical to shallow water applications. The 1.5-MHz profiler is available as a Mini-ADP featuring a compact transducer head designed for applications where small size is critical.

Rugged build quality with high-end ADV® performance is what the ADVOcean-Hydra is all about. Representing the ultimate solution to measuring precise 3D velocity in the most challenging environments, the ADVOcean/Hydra can be integrated with an array of external sensors for a complete oceanographic data collection system. With the optional RPT pressure sensor, this powerful system is able to sample both pressure and velocity at up to 25 Hz, making it the definitive solution for studying nearshore processes.

Providing robust velocity measurements in a compact, easy-to-use package, the SonTek Argonaut-ADV is the ultimate instrument for shallow water flow monitoring. Ideal for low-flow applications in shallow streams, marshes, lakes, or water treatment facilities, the 3-axis (3D) Argonaut-ADV`s advanced Doppler technology measures single-point velocity away from flow obstructions. All signal processing is done internally, allowing the Argonaut-ADV to be readily integrated with a wide range of additional sensors.

The Argonaut-XR offers exceptional value for near shore deployments in less than 40 m of water. Designed specifically for mounting on the bottom of a river, channel, or harbor, the XR features a special mode that automatically adjusts one of its measurement cells for changing water level. Its small size, rugged build, and flexible system architecture make the XR attractive for both real-time operation and autonomous deployments.

The CNSolution™ 9310 Online Cyanide Analyzer improves accuracy of cyanide detection in precious metal leaching solutions by offering a dynamic continuous-monitoring approach, significantly reducing operating costs.

The Flow Solution 3700 Automated Chemistry Analyzer is an efficient, flexible, and easy-to-use tool for automated wet chemistry analysis. Improve laboratory workflow with the FS3700 by running multiple flow methods (including SFA, FIA, iSFA, and SFIA) on different channels simultaneously. Ideal for the analysis of ammonia, chloride, cyanide, fluoride, nitrate, phenol, phosphorous, silica, TKN, and more!

The Flow Solution FS 3100 Automated Chemistry Analyzer is a modular system for performing continuous flow analysis methods on water samples, soil, or plant extracts and digests using FIA or SFA techniques. The FS 3100 consists of an X-Y-Z autosampler (90 or 360 position), multi-channel precision pump, electrically-actuated sample injection valve, VersaChem Multi-Test Manifold, and Expanded Range photometric or amperometric detector.The FS 3100 supports two channels for FIA methods and three channels for SFA methods, minimizing the time involved in changing chemistries for different analytes.

The Flow Solution IV+ (FS IV+) is a powerful automated chemistry analyzer for performing high throughput continuous flow ion analysis methods. The FS IV+ supports and performs two types of continuous flow analysis techniques: segmented flow analysis (SFA) and flow injection analysis (FIA).The FS IV+ consists of a 360-position autosampler, a 24-channel peristaltic pump, a power base module (with 4 independently controlled heaters and 4positions for analytical cartridges), and a detector module equipped with 1 to 3 detectors and flow cells depending upon analytical requirements.The FS IV+ can be configured for simultaneous operation of 2 or 3 analytical channels and is expandable for up to 6 analytical channels when equipped with an additional power base and detector module. Optional modules are available to perform automatic dilutions and sample preparation techniques, including: on-line distillation or extraction, UV digestion, and membrane separation.
