Noun
/pˌiːˈeɪtʃ ˈskænər/
A pH scanner is an electronic device used to measure the pH level of a solution, which indicates its acidity or alkalinity. This device is prevalent in scientific research, agriculture, aquaculture, food production, and environmental monitoring. The phrase "pH scanner" is more often found in written contexts such as technical documents, scientific articles, or product descriptions rather than conversational spoken English.
The researchers used a pH scanner to assess the acidity of the water samples collected from the river.
Исследователи использовали pH-сканер для оценки кислотности водных образцов, собранных из реки.
A pH scanner is essential for monitoring the health of aquaculture environments.
pH-сканер необходим для мониторинга состояния аквакультурных сред.
The pH scanner indicated that the soil was too acidic for optimal plant growth.
pH-сканер показал, что почва была слишком кислой для оптимального роста растений.
While "pH scanner" does not typically appear in idiomatic expressions, the concept of pH can be metaphorically related to balance or equilibrium in various contexts. Here are a few related idioms:
It’s crucial to maintain a pH balance in the skin to prevent dryness.
Важно поддерживать pH-баланс кожи, чтобы избежать сухости.
"Crossing the pH threshold" can imply going beyond acceptable limits or standards.
When the water quality report showed values crossing the pH threshold, the aquarium’s health was at risk.
Когда отчет о качестве воды показал значения, превышающие pH-предельные значения, здоровье аквариума было под угрозой.
"Testing the pH waters" suggests trying something new or testing out a new situation.
The term "pH" comes from the French "p" for "potenz" (power) and "H" for "hydrogen," which was coined by the Danish chemist Søren Sørensen in 1909. The word "scanner" is derived from "scan," which comes from the Latin "scanere," meaning "to climb" or "to leap," insinuating the device's ability to measure and decode information.
Synonyms:
- pH meter
- Acid-base tester
- pH sensor
Antonyms:
- Alkaline tester (not an exact antonym, as the devices measure different aspects, but could imply the opposite property in terms of pH levels)
In conclusion, the term "pH scanner" is specific to scientific and technological discussions surrounding acid-base measurement, and while it does not appear in common idiomatic expressions, its understanding is crucial across various fields.
