MicroLAB fish kill application: Sales of our new compact and affordable nutrient monitoring system, MicroLAB, have exceeded all expectations. MicroLAB systems have been integrated into new monitoring and research application areas.

MicroLAB is set up to take a sample once an hour every day, uploading real-time data to the USGS’ Web site, which beats the less frequent, manual method scientists were using before.
Multi-channel stream-side monitoring in Scotland: The Center for Ecology and Hydrology (CEH) have installed a new multi-channel AutoLAB for nitrate, phosphate and silicate measurement at an existing monitoring site in Greens Burn near Edinburgh, Scotland. The AutoLAB was supplied with a pump, controller and sample flow-cell to allow it to automatically sample from the adjacent stream. Greens Burn is in an area of farm land with relatively high annual rainfall. CEH are involved in projects to investigate the relationships between pressures, chemical status, and biological quality elements in the environment.
NOAA/PMEL Upgrade Entire NAS Fleet: Researchers at the Pacific Marine Environmental Laboratory in Seattle decided on full factory upgrades for all their NAS-2E analyzers. The cost effective upgrade has provided a fleet of like-new systems with all the advanced technology features of a NAS-3X at a fraction of the cost. The systems are now being used within a wide range of applications from traditional moorings work to new areas such as automated surface mapping aboard commercial vessels. Ask for details about the NAS upgrade kit and optional installation service and protect your initial investment.
Ren Star deliver MicroLAB to NAHRIM, Malaysia: The National Hydraulic Research Institute of Malaysia (NAHRIM) have purchased a MicroLAB system for use in applied research within their coastal engineering, water resources development and water quality applications. The complete MicroLAB package was supplied with nitrate and phosphate detectors to enable investigators to very cost effectively swap between application areas by simply exchanging the colorimeter and uploading the appropriate analysis scripts.
Joshua Walker, EnviroTech's Product Specialist, traveled across the world to provide a comprehensive training course to the researchers at NAHRIM.
Intelligent Sampling Systems: In response to the challenge of developing "smart" and adaptive sampling systems researchers at the The University of Maryland Center for Environmental Science (UMCES) Horn Point Lab (HPL) have developed an adaptive integrated monitoring system (AIMS) that incorporates nutrient analysis, water sampling, sensor measurements, data logging, telemetry and data-to-web components. The work is funded by NOAA MERHAB and includes EnviroTech's nitrate and ammonium analyzers and a ESM Plus acquisition and control system. A new urea monitoring system is currently being added (see below). Full details at the AIMS website.
New Aqua Monitor for NIWA: We have recently delivered a new version of our unique Aqua Monitor deep ocean water sampling system to NIWA, New Zealand. Rated for use to 4000 m depth and upgraded to include our new titanium sample valve technology the system can collect 50 individual or integrated 1000 ml samples.
Samples can be used for analysis of nutrients, microplankton and suspended load or as calibration samples for other sensors on the mooring. The intelligent ESM controller provides huge programming flexibility allowing time-series, burst, integrated or conditional sampling and subsequent in-situ processing as needed. Threshold or triggering algorithms can be designed by the user with the flexible Eco-Script language.
The system has an all-new modular and compact deployment frame design.
Monitoring Maumee River, Lake Erie with EcoLAB: Researchers at the University of Toledo, Lake Erie Center and the NOAA Great Lakes Research Laboratory are using EcoLAB to investigate the feasibility of characterizing the river plume with high frequency measurements including nutrients. To capture and understand rapid changes in water chemistry continuous in-situ measurements are needed at a temporal resolution not viable with traditional manual sampling methods. The EcoLAB is deployed in the waters of Maumee Bay near a lighthouse and will ultimately provide real-time on-line nitrate and phosphate data to allow potential conditions for algal blooms to be identified as they unfold.

NAS-3X upgrade kit: Following the release of the new NAS-3X model of in-situ nutrient analyzer, every NAS-2E can now be cost effectively upgraded to the new NAS-3X standard. The new boards include all the features of our multi-channel analyzers including serial port upgradeable firmware. An all new low-noise, high-precision detector board provides better light and heat control and data acquisition from your existing "2E" hardware. Please contact us for further details.
Real concentrations in real-time: Recent firmware and script updates now add add a real-concentration output option to all our analyzer systems. The "most requested" feature now allows easy integration with telemetry systems and graphical displays on customer web pages. Also new is the SDI-Cipher that adds SDI-12 functionality to our analyzer and sampler products.
Urea Method Development: Use of urea as an agricultural fertilizer over the last decade has surpassed ammonium nitrate, bringing into question its use and impacts. The growing need to monitor and understand the effects of urea in watersheds and coastal regions has led a team at Horn Point Laboratory to adapt our NAS-3X analyzer for direct measurement of urea. Through a collaborative effort we have implemented and interfaced a colorimeter specifically for the method. The programmability of the NAS-3X has allowed the team to easily implement the chemical method.
Additional sensors for U-Tow: The lastest update to the U-Tow system and Ocean Windows software includes dual inputs for the Sea-Bird SBE 49 FastCAT CTD sensor proving a very high spatial resolution of oceanographic structures and gradients with 16 Hz sampling.
New intelligent valve drive: A new ultra-reliable valve drive mechanism has been developed for all our current products that incorporates a high-precision shaft-encoder and feedback mechanism for highly repeatable and accurate valve positioning.The new drive system automatically compensates valve alignment in real-time and invokes re-alignment in case of any problems. The design also includes a new high quality motor and gearbox assembly that provide significantly increased torque and rotary speed allowing the valve to travel reliably at higher speeds. This reduces the power budget and analysis time by up to 30%. We are always careful to ensure our customers have an upgrade path and this development is no exception. All current and some older products (the NAS-2E) can be fully upgraded to take advantage of this significant development. Please contact us for further details.
