Dissolved Oxygen Sensors
Tips & Advice to help you make your decision on Dissolved Oxygen Sensors
Whether the concern of the business is the environment or industrial processing, dissolved oxygen sensors can be beneficial to the business. In addition to testing water to determine impact on ecosystems, these sensors are also utilized during certain applications within the industrial setting. They work by deciphering the amount of dissolved oxygen that is present in the water and provide a read out. However, there are different types of these sensors which are available on the market. Understanding the differences among these can help ensure that your business is obtaining the best sensor for their company that will yield maximum results.
There are three main types of dissolved oxygen sensors. These include but are not limited to optical, galvanic and what is known as a polarographic dissolved oxygen sensor. Although these are typically used by most businesses, there are other varieties which may be available. To ensure that your company is purchasing the right sensor for the business needs, check out the information at Business.com. They can offer your business the help that may be needed and even direct you to suppliers and manufacturers that can meet these needs. Click on the links to the left to find out more.
Dissolved Oxygen Sensors
Use dissolved oxygen sensors to determine marine ecosystem concentrations and to control industrial processesBy W. Aiman Mueller Dissolved oxygen (DO) sensors and probes detect levels of dissolved oxygen in liquids, typically water, usually for biological measurements and for industrial process applications. Readouts will usually display dissolved oxygen concentration in either parts per million or milligrams per liter.
Another type of readout involves comparing a calculation of the maximum dissolved oxygen concentration with the actual concentration, expressed as a percentage. The variables that affect the maximum concentration are the atmospheric pressure just above the liquid, the temperature of the liquid, and the presence of other substances in the liquid.
Here are a few different types of dissolved oxygen sensors:
1. Galvanic dissolved oxygen sensors employ electrodes and remain stable and accurate even at low dissolved oxygen concentrations. Another benefit is that they do not require frequent replacement of electrolyte fluid.
2. Polarographic dissolved oxygen sensors also employ electrodes, but require the addition of an external voltage input and relatively frequent replacement of electrolyte fluid.
3. A optical dissolved oxygen sensor does not use electrolyte fluid at all, but an optode instead. In this case, an optical cable detects a film that reacts to dissolved oxygen with fluorescence.
Shop dissolved oxygen sensor suppliers that also carry accessories
Various types of dissolved oxygen sensor instruments require different supplies to keep them operating. Especially if you intend to put your dissolved oxygen sensor equipment to heavy use, shop DO sensor sources that also carry the supplies.
Try: Veriner carries a sensor with a range of 0 to 14 mg/l. They also sell filling solution, calibration solution, membranes and other supplies to keep the sensor operating. Sensorex sells both lab and process dissolved oxygen probes. They also carry supplies and accessories to help their customers get longterm use out of their products.
Locate industrial dissolved oxygen sensors that suit your needs
Controlling dissolved oxygen levels in industrial processes helps optimize efficiency of production and quality of product. Chemical reactions often require the control of oxygen levels. Some dissolved oxygen sensor manufacturers specialize in this type of equipment.
Try: Mettler Toledo carries several products for sterile processes, as well as low level situations. They also have a waste water dissolved oxygen sensor. If you're looking for hand-held dissolved oxygen meters, then Instrumart is your place. They carry several models designed specifically for industrial processes.
Buy a quality optical dissolved oxygen sensor
Sometimes divers and biologists prefer the newer optical technology which requires relatively less care. Some conventional sensors have more variables due to changes in the electrolyte fluid during heavy use. Also, optical sensors often work better in stagnant water.
Try: AADI specializes in oceanic science and has many quality sensors, including the optical dissolved oxygen sensor. Another source is Global Water Instrumentation, Inc. which carries a model that features long life, bio-fouling resistance; their unit is unaffected by water current or a lack thereof.
