The purity and even the taste of drinking water can be affected by pH and ORP, and these properties are also applied in synthesizing flavor compounds and reducing toxicity in fermentation. Regular monitoring of ORP values in wastewater treatment allows high level decision-making concerning what, when, where and how much oxygen, air or other chemicals are to be added, ensuring the highest possible quality and safety. Other applications for the SD-230 pH/ORP meter include aquariums, fish hatcheries, laboratories, food processing, photography, and swimming pools. Readings can be recorded directly to an SD card, allowing data to be exported to MS Excel for analysis.
