Electrical conductivity is the most convenient method for testing RO water quality and membrane performance. Pure water is actually a poor electrical conductor. The amount of ionized substances (salts, acids, or bases) dissolved in water determines its conductivity. Normally, the vast majority of the dissolved minerals in tap, surface or ground water
Though they all must support routing functionality, some devices do it better than others.
Routing consumes more energy, so the lifetime of the battery will be affected. Therefore, a device with a battery that is inexpensive, has a long lifetime, and is easy to change would be ideal. With all this considered, a WirelessHART temperature transmitter is a suitable option to operate as a repeater.
Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.
The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.
Polycyclic Aromatic Hydrocarbons (PAHs) are a large group of organic compounds found naturally in the environment. PAHs are monitored by the US Environmental Protection Agency due to their carcinogenic characteristics.
In 2012, Americans consumed well over 79 billion servings of tea, which is just over 3.60 billion gallons.
Hexanal is one of many well-documented aromatic components that contribute to flavor and aroma in common consumer food products containing omega-6 fatty acids. Hexanal content is also used to measure the oxidative status of foods rich in omega-6 fatty acids.
Water quality laboratories across the nation are faced with both a rising level of water quality awareness amongst the general public, as well as rising costs in water quality monitoring. As a result, laboratories are looking for more efficient ways to provide higher quality monitoring.
Numerous compounds contribute to changes in beer flavor as it becomes stale. One of these compounds, (E)-2-nonenal, has been investigated as a major source of the papery/cardboard flavor that develops in aged beer.
The analysis of Total Organic Carbon (TOC) in seawater can be both challenging and expensive. The concentration of organic carbon in seawater is of considerable interest. The effect this matrix can have on TOC analyzers can lead to rapid consumable turnover, costly maintenance and repairs.
