Intelligent dissolved oxygen analyser protects
surface and tank water storage systems Municipal water systems engineers concerned about protecting large surface and tanks water storage systems, will want to consider how the advanced S80-T80 Dissolved Oxygen Analyser from Electro-Chemical Devices (ECD) helps them easily, accurately and economically measure dissolved oxygen (DO) levels to ensure they protect municipal water supply storage systems as well as protect sensitive ecosystems
Oxygen is naturally present in bodies of water and its levels are measured as dissolved oxygen (DO). These water resources receive their oxygen from the atmosphere and from
aquatic plants. Running water, such as that of a swift moving stream, dissolves more oxygen than the still water of a large pond or lake. All aquatic animals such as fi sh, including those farmed for human consumption, need adequate levels of DO to breathe, feed and thrive.
ECD’s easy-to-use, economical S80-T80 DO Analyser with its intelligent S80 sensors and intuitive T80 transmitter is the perfect solution for oxygen measurement. This analyser comes pre-calibrated from the factory, requiring no special tools or installation training. It’s a plug-n-play system that’s ready-to- go out of the box and designed for busy water engineers and techs.
The U.S. Environmental Protection Agency (EPA) warns that low levels of oxygen (hypoxia) or no oxygen levels (anoxia) can occur when excess organic materials, such as large algal blooms, are decomposed by microorganisms. During this decomposition process, DO in the water is consumed. Knowing DO levels allows technicians to remediate issues early on in vital surface water systems with dual use, such as those for both consumption and recreation.
Low oxygen levels often occur in the bottom of the water column and affect organisms that live in the sediments. In some water bodies, DO levels fl uctuate periodically, seasonally and even as part of the natural daily ecology of the aquatic resource. As DO levels drop, some sensitive animals might move away, decline in health or even die, contributing to the decline of important natural resource ecosystems.
To prevent these issues, municipal water engineers and industrial technicians often must monitor DO levels—especially in municipal surface water storage systems consisting of reservoirs, lakes, ponds and tanks or enclosure pens for aqua-culture or fi sh hatcheries. Failure to maintain suffi cient oxygen levels also can jeopardize municipal drinking water quality, available supplies and jeopardize sensitive wildlife.
When the intelligent S80’s sensor is connected to the versatile T80 Transmitter, the sensor’s information is uploaded to the analyser. It then confi gures the displays and outputs of the transmitter to the values appropriate to the DO sensor’s measurement parameters. The S80-T80 DO Analyzer measures dissolved oxygen levels from 0 to 20 ppm (mg/L) at 250 percent saturation. They operate over a pressure range of 0 to 50 psig and at temperatures (-5 to 80°C).
The standard S80 sensors have 316 Stainless Steel housings although various materials of construction are available to maximise sensor performance while minimizing cost of ownership. They are available in either a choice of insertion or valve retractable confi gurations for quick disconnect and replacement of sensor cartridges.
The universal T80 Transmitters are available as either single channel or dual channel instruments. This transmitter comes in a 24 VDC or a 100/240 VAC power confi guration. All versions are available with the optional HART®
output. These line powered instruments have one 4-20 mA output per
channel and a MODBUS RTU. Other options include a three-alarm relay package confi gurable as alarm (set point) relays, timer activated relays or fault relays.

Revolutionary autonomous aquatic eDNA sampling solution for marine
and freshwater applications NatureMetrics and Dartmouth Ocean Technologies (DOT) have announced the commercial launch of the DOT-NM Autosampler. This cutting-edge system enables the autonomous collection of eDNA samples from marine and freshwater environments to provide comprehensive biodiversity insights at an unprecedented scale.
The DOT-NM Autosampler addresses a critical bottleneck in aquatic environmental monitoring by autonomously sampling eDNA - genetic material naturally shed into waters by organisms - over extended deployments without requiring labour-intensive vessel-based campaigns. This groundbreaking capability unlocks safe, cost-effective, and continuous biodiversity data collection, even in the most remote aquatic locations.
After rigorous validation, the autosampler has proven to generate eDNA data with equivalent species detection and biodiversity resolution to conventional manual sampling methods performed by human crews. Leading environmental survey provider Fugro is now planning commercial deployments, leveraging its autonomous sampling capabilities over multi-month offshore campaigns to reduce operational costs signifi cantly compared to cyclic vessel-based surveys.
The autosampler seamlessly integrates with NatureMetrics’ end-to-end nature intelligence reporting workfl ow powered by eDNA technology and cutting-edge bioinformatics. Following autonomous sample collection utilising NatureMetrics’ proprietary eDNA fi lter technology, samples are processed through a state-of-the-art eDNA laboratory. The resultant data is then analysed using NatureMetrics’ pioneering DNA metabarcoding pipelines to identify species in the study area. Comprehensive biodiversity insights are delivered to clients via the NatureMetrics Intelligence Platform, featuring interactive data visualization and reporting tools tailored for environmental decision-making.
This integrated online solution not only simplifi es marine and freshwater environmental monitoring programs by replacing often complex logistical supply chains, but provides practitioners with auditable, actionable datasets - fi nally aligning the biological data collection with the spatial and temporal resolutions required for robust environmental management.
Leveraging DOT’s expertise in designing rugged oceanographic instrumentation, the autosampler system is engineered for reliable operations across a diverse range of conditions in aquatic environments. The autosampler provides autonomous collection of up to 9 consecutive 5-litre eDNA samples per deployment and features user-confi gurable sample timing and volume settings based on study requirements. This user-friendly device performs automatic sample preservation and self-cleaning routines between samples and has three depth rating options for 20m, 200m and 2000m deployments. The DOT-NM Autosampler can be deployed from a vessel, a static mooring or integrated with drones or AUVs and is ideal for a host of applications, including marine conservation, offshore energy, aquaculture and wastewater monitoring
By unlocking systematic, repeated eDNA sampling, the DOT-NM Autosampler captures a holistic biodiversity picture previously unattainable through intermittent, patchy surveys. This includes detecting migratory and nocturnal species and resolving ecosystem changes over time, which are crucial environmental baselines for effective monitoring and management programs.
With signifi cantly reduced HSE exposure, cost, and carbon footprint savings compared to manual surveys and proven data quality, the DOT-NM Autosampler is poised to drive the proliferation of eDNA-based biodiversity measurement across industries.
