New Models for 2010
New models of our EcoLAB in-situ analyzer, the AutoLAB field analyzer and Aqua Monitor smart water sampler have been released. Each delivers new features and technical advances to make in-situ analysis and sampling easier and more reliable. Some exciting application are outlined in the articles below and full technical details are available from our website.
Aqua Sentinel – Continuous Monitoring of Chemicals in Process Applications
We have added the all new Aqua Sentinel multi-channel on-line analyzer system to our product range. Designed for fixed in-take, effluent and process control monitoring.

Applications so far include aquaculture research, nutrient limitation experiments and petro-chem process monitoring.

Designed for easy and cost effective continuous monitoring of nutrients and other dissolved chemicals Aqua Sentinel is capable of providing high-frequency data for extended periods in a very wide range of process-type applications.		 Aqua Sentinel
EcoLAB Goes Sub-Antarctic for Deep Ocean Nutrient Analysis
A new version of EcoLAB was developed for a borehole deployable Geochemical Instrumentation Package for Sub Ice Exploration (GIPSIE). Developed at Northern Illinois University, GIPSIE consists of a large array of oceanographic instrumentation and sensors that enable physical and geochemical characterization of marine and freshwater sub-glacial environments through in-situ measurements and water sampling. Parameters include nutrients (SiO4, NO3, PO4 and NH4) chlorophyll, CTD, dissolved oxygen and many others.

The design challenge was to increase EcoLAB’s depth rating from 100 m to 4000 m and streamline it physically to fit through a 200 mm diameter borehole through the Antarctic ice. With necessity being the mother of invention great technical advances were made during the development of these custom systems that now benefit all our customers.

The EcoLAB systems analyze nutrients in real-time during GIPSIE’s deployment and the array also includes a deep-rated Aqua Monitor water sampler subsequent lab analysis up to 48 individual or integrated samples.		 EcoLAB 2 - 4000 m rated

Chemical Monitoring in the Savannah River with AutoLAB
AutoLAB Station on the Savannah River Savannah River in the United States forms the boarder between the southeastern states of South Carolina and Georgia. The river basin provides water for two large cities – Savannah and Augusta – with over 1.5 million people, significant hydropower, a large industrial sector and a major port. The Savannah River is one of the most stressed in the region.

Working with the US Army Corp of Engineers (USACE) five AutoLAB analyzer systems were adapted to monitor chloride concentrations as part of a network of monitoring stations deployed over a stretch of the river 12 miles (19 km) to the northwest of Savannah. Working with the Army Corp Costal Hydraulics Lab and Instrumental Solutions, AutoLAB has been integrated as part of a suite of sensors, datalogger and internet based wireless telemetry.

Problem Solving & Engineering Solutions: Probe Guard Anti-Fouling System

We have been helping Green Eyes, LLC of Cambridge, MD in their mission to develop a new generation of devices and systems that reduce the cost of continuous monitoring while significantly increasing data quality.

A potentially revolutionary anti-fouling system is now emerging from Green Eyes. Probe Guard prevents the costly problem of biofouling on all types of electronic sensors and multi-probes. It works by enclosing sensors in a chamber that is treated with biocide, and then opened and flushed at a programmed sampling interval. Keeping sensors clean and functional for long periods dramatically reduces the huge impact service costs have on stretched monitoring budgets.

EnviroTech has provided mechanical and electronic support for Green Eyes and many other customers in need of carefully engineered solutions. We are ready to help you too.		 Probe Guard
