Oct. 25, 2021 - Water engineers, environmentalists and aquaculture technicians will find the S80-T80 Dissolved Oxygen Analyzer from Electro-Chemical Devices (ECD) helps them easily, accurately and economically measure dissolved oxygen (DO) levels to ensure they support sensitive ecosystems, as well as municipal water storage and fish farming.
Dissolved oxygen is the amount of oxygen that is naturally present in bodies of water. These water sources 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 pond or lake. All aquatic animals such as fish need adequate levels of DO to breathe.
The easy-to-use, economical ECD S80-T80 DO Analyzer with its intelligent S80 sensors and intuitive T80 transmitter is the perfect solution for measurement. This analyzer 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.
According to the U.S. Environmental Protection Agency (EPA), 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.
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 fluctuate 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.
To prevent these issues, environmentalists, 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 fish hatcheries. Failure to maintain sufficient oxygen levels also can jeopardize municipal drinking water quality 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 analyzer. It then configures 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% 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 maximize sensor performance while minimizing cost of ownership. They are available in either a choice of insertion or valve retractable configurations 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 configuration. 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 configurable as alarm (set point) relays, timer activated relays or fault relays.
