Alkalinity

Alkalinity is a measure for the buffer capacity of natural waters. It gives the amount of acid that needs to be added to cause a color change of the indicator methylorange (m‑value, pH 4.3) or phenolphthalein (p‑value, pH 8.2). Alkalinity is mainly caused by a combination of carbonate, bicarbonate, and hydroxide ions. If the alkalinity is high, the addition of acids or bases has only a little influence on the pH.
Alkalinity inhibits corrosion in boiler and cooling water. Additionally, alkalinity is an important parameter for quality control in process water, aquariums, and swimming pools.

Humidity, Relative

Products that are sensitive to moisture must be kept dry. To achieve this, such products are often packed in PE bags with a desiccant. Moisture indicators allow a simple, visual control whether the product is still kept dry. Conventional moisture indicators are based on cobalt chloride, which is classified as toxic and carcinogenic.

Nitrate

Nitrate is a by‑product of biological decay from plant and animal matter (nitrification). Nitrate is reduced to nitrite easily, which can lead to diseases and increased fish mortality. Furthermore, high concentrations of nitrate itself are also harmful. Such concentrations are found predominantly in agricultural areas where nitrogen fertilizer is regularly used.

Nitrite

Nitrite is produced as an intermediate in the nitrification in sewage treatment plants. An excessive content of nitrite indicates that the plant’s biology does not work optimally.
