electronic balance
Học thuậtThân thiện
Definition
- Noun:
- A precision weighing instrument: An "electronic balance" is a device used to measure the mass of an object with high accuracy. It operates by generating an electrical signal proportional to the weight placed on its weighing pan.
- A modern weighing device: It represents a type of balance that uses electronic components, such as a load cell and a digital display, as opposed to traditional mechanical balances that use physical beams and counterweights.
Usage Examples
- Noun:
- The chemist used an electronic balance to measure exactly 2.5 grams of the compound.
- For this experiment, you must weigh the sample on a calibrated electronic balance.
- The electronic balance displayed the weight instantly on its digital screen.
Advanced Usage
- "Tare function on an electronic balance": This refers to the feature that allows the user to reset the display to zero with a container on the pan, so only the weight of the added contents is measured.
- Place the beaker on the pan and press 'Tare' to zero the electronic balance before adding the powder.
Variants and Related Words
- Analytical balance (n): A very high-precision type of electronic balance, often enclosed in a draft shield, used for extremely accurate measurements, typically in laboratory settings.
- The sample was weighed to four decimal places using an analytical balance.
- Digital scale (n): A broader term that can include electronic balances as well as other types of digital weighing devices for various purposes (e.g., kitchen scales, bathroom scales).
- The postal worker used a digital scale to determine the postage.
Synonyms
- Digital balance: A balance that provides a numerical, digital readout of the weight.
- Precision scale: A scale designed for accurate and precise measurement.
Related Phrases
- To calibrate an electronic balance: The process of adjusting the balance using known standard weights to ensure its measurements are accurate.
- The laboratory technician must calibrate the electronic balance monthly.
- The readout of an electronic balance: The numerical value shown on the display.
- Record the readout of the electronic balance in your lab notebook.
Noun
- a balance that generates a current proportional to the displacement of the pan
