Selecting Among Dissolved Oxygen Measurement Methods (Optical, Galvanic, Polarographic)

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.

How to Reduce pH Sensor Maintenance (Part 2)

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.

Understanding Conductivity Cell Constants

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.

Making Sense of Conductivity, TDS, and Concentration in Water Treatment

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.

Choosing an Industrial pH Sensor

How do you know which industrial pH sensor is the perfect choice for your application? The different number of industrial combination pH sensors out there can be overwhelming. Before making an industrial pH sensor purchase, it is crucial to have a better understanding of your application and the conditions the sensor will be enduring while [...]

Combining Oxidation and UV Disinfection to Improve Water Treatment Efficiency

Water Treatment Methods There exist several mechanisms for water disinfection, including chlorination and chloramination, ozonation, and UV irradiation. Ordinarily, only one disinfection technique is used in a treatment train. However, there are potential benefits to combining water treatment methods in sequence, including energy and cost savings and a safer product water. Potential Benefits of Combination [...]

How to Monitor Aquarium Water pH and Other Water Quality Parameters

The Importance of Aquarium Water Quality Like all organisms, the fish and aquatic plants in your aquarium rely on highly specific environments in order to survive. These essential conditions vary from species to species and depend on the environment in which they evolved. Aquarium Water pH pH measures the acidity or alkalinity of water. [...]

pH Calculation by Differential Conductivity Measurement in Pure and Ultra-Pure Water

Summary In all kinds of water steam cycles, the correct pH measurement in power plants play a key factor in corrosion risk surveillance. A measurement with a glass pH electrode is possible but requires a pH probe designed for low conductivity, high temperatures and pressure. An accurate pH value can also be obtained by measuring the [...]

How to Choose the Best pH Sensor: Laboratory Style Sensors

You want a sensor that will provide the best measurement accuracy with the maximum lifetime, but the number of different laboratory pH sensors out there can be overwhelming. Before making a laboratory pH sensor purchase it is crucial to have an understanding of your application and the conditions the sensor will endure while in use. Based on this knowledge you can make a decision on what features are required.
