Commercially available dissolved oxygen sensors typically fall into 3 categories: galvanic dissolved oxygen sensors, polarographic dissolved oxygen sensors, and optical dissolved oxygen sensors. Each type of dissolved oxygen sensor has a slightly different working principle. Therefore, each dissolved oxygen sensor type has advantages and disadvantages depending on the water measurement application where it will be used.
Have you ever heard of zebrafish? If you’re not part of the scientific research community, maybe not. Believe it or not, zebrafish and humans share similar genetic and biological structures, making them a model organism. It’s important for researchers to ensure that zebrafish are being kept in nearly identical conditions across multiple habitats. Oxygen levels, contaminants, pH levels, and salinity can all impact fish health.
Reference poisoning is a major failure mode for pH sensors. This blog post explains the causes of pH sensor reference poisoning. We also share tips for selecting products that are less likely to experience reference poisoning, so that you can spend less time maintaining your sensors.
Cleaning your pH probes is essential to ensuring that they measure accurately. Unfortunately, pH probe cleaning can be hassle. Cleaning pH probes can mean removing them from your process and taking time out of your day. Learn how to spend less time cleaning pH probes, with flat surface self cleaning pH glass.
In industrial applications, cooling can be critical to ensure that processes do not cause equipment or products to overheat. Many cooling applications use water as a medium to absorb heat, because water has a high boiling point and high specific heat. There are many different ways to set up an industrial cooling system, but the three basic types can be summarized by examining how cooling water is used in each system.
To comply with EPA regulations, businesses are often required to monitor wastewater effluent or stormwater runoff. Potential polluters monitor pH, conductivity, dissolved oxygen, and other parameters to ensure that the water they release into the environment is in line with EPA standards. Learn more in this guest blog by WaterLogic International.
As a result of the risks posed by ballast water, many shipping companies have begun to monitor their ballast water tanks. Many governments have also implemented ballast water regulations. Ballast water monitoring is becoming essential for meeting regulatory requirements and protecting the environment. Every shipping company should have a ballast water management plan in place.
Making the perfect batch of wine is a matter of producing the best combination of taste, smell, and color. Did you know that wine pH impacts all of these? We explain the impact of pH on the winemaking process and how to measure wine pH levels for best results.
There are several different kinds of sensors for measuring conductivity. Choosing a sensor that fits your application will improve accuracy and ensure longevity of your equipment. One important factor to understand before choosing a conductivity sensor is how to select a conductivity cell constant.
Different applications require different levels of water purity. As an example, the electrical conductivity of drinking water will usually be less than 1 mS/cm, while a semiconductor plant or pharmaceutical plant requiring very pure water would aim for the electrical conductivity of water to be less than 1 µS/cm.
