An analytical balance is designed to measure the mass of substances to a high degree of precision. These scales read masses to within 0.0001 gram.
Fingerprints add mass. For this reason, a tare container should never be picked up with bare hands when using an analytical balance. Instead, Kimwipes or tongs should be used to place and remove the container from the apparatus. The mass of the container should be recorded. Avoid leaning on the laboratory bench while weighing the substance. When adding the substance to be weighed, do not expect to reach an exact mass. To clean an analytical balance, use a brush to wipe away any spills.Learn More
An anemometer measures wind speed and, sometimes, wind direction. The anemometer is an important tool used by meteorologists to help predict the weather and record the current weather conditions.Full Answer >
Seismographs measure vibrations produced during earthquakes. All earthquakes, regardless of size, generate vibrations deep within the earth. These vibrations are caused by the breaking and fracturing of rock and organic materials along fault zones; seismographs detect and record the frequency, duration and magnitude of all vibration waves emitted from earthquakes.Full Answer >
A chronometer is an clock or watch that is extremely accurate at measuring time. Watches must go through a series of tests conducted by the Swiss Official Chronometer Control in order to be designated as chronometers. The institute issues a performance certificate to watches that pass the tests.Full Answer >
Measure liquid in a syringe by observing the liquid's level against the scale on the syringe. Draw liquid into the syringe using the plunger until the right quantity is achieved and observed next to the desired increment of the scale, as stated by the National Prescribing Service.Full Answer >
