Using Multiparameter Meter at a Electroplating Plant

The most important parameters of the electrolytes used for electroplating ('plating bath' in technical parlance) include the pH. Depending on the nature of the plating method, the electrolytes can be acidic, basic or neutral. In case of this company, the pH value can vary between 1 and 13 pH, depending on the technology.

Winemaking and pH

The pH of wine is important to determine because it will affect the quality of the product in terms of taste, color, oxidation, chemical stability and other factors. This white paper describes the importance of pH in winemaking.

Chlorine and ORP Webinar

On July 23, 2010 HANNA Instruments USA President David Minsk and technical application specialist Michael Bogolawski hosted a webinar regarding sales of Chlorine and ORP (Oxidation Reduction Potential). This white paper is a review of that webinar.

Disinfection and Chlorine Facts

Disinfection is a process of killing disease-causing organisms (or pathogens). Chlorine (Cl2) is a very desirable disinfectant because, when mixed with pure water, it reacts to form hypochlorous acid (HOCl) and hydrochloric acid (HCl). HOCl (free active chlorine) is the most effective form of chlorine for disinfection. Read this white paper to find out more about Disinfection and Chlorine.

pH measurements in Irrigation Water

pH measurements is one of the most important disciplines a grower should perform. When I visit a grower who is experiencing a less-than-healthy crop and ask what the root medium pH is, the response is often, "I don't know." Find out more about pH in Irrigation Water by reading this white paper.

The importance of pH and Temperature in Beer

Beer is a food product that is fermented, and like all food products, process monitoring and sanitation are of paramount importance for clean, consistent results. From incoming raw materials to finished packaged beer, the pH, temperature, and a host of other parameters will determine whether the beer in the bottle will taste the same way every time. Learn more about pH and temperature in Beer by reading this white paper.

Improved pH Measurement

Reprinted from American Laboratory News February 2004, this article goes over improvements of pH measurement such as the combination electrode, more versatile pH glass, high-performance electrode junctions, and application-specific electrodes.

Care and Storage of a pH Electrode

The life of your pH electrode is not infinite. A number of factors affect the life span of your pH electrode. The higher the temperature that the electrode is used at, the more extreme the pH, how often the bulb dries out and needs to be rehydrated, how roughly it is used; all these factors and more shorten the life span of your electrode. Read this white paper to find out how to take care of your pH electrode.
