econdary instruments are calibrated.absolute instruments are not calibrated.
secondary instruments are used everywhere,ab instru are only in labs or std institutions.

What is used to measure density?
A very common instrument for the direct measurement of the density of a liquid is the hydrometer, which measures the volume displaced by an object of known mass. A common laboratory device for measuring fluid density is apycnometer; a related device for measuring the absolute density of a solid is a gas pycnometer. Another instrument used to determine the density of a liquidor a gas is the digital density meter - based on the oscillating U-tube principle.
What is the difference between absolute threshold and difference threshold?
absolute threshold is the lowest level that a person will feel sensation differential threshold is the minimal difference that a person can detect between two similar stimuli For example a change in volume in certain frequencies would be crossing the absolute threshold, how much that change would need to be for someone to detect it would be dealing with the difference threshold.
What is preventing science from making a perfect vacuum are there any fundamental principles that would be violated?
For example in the most strong cosmic vacuum are millions of neutrinos. And in an installation increasing the temperature and the power of the pump the degassing continue down to the minimal resolution of the measuring instrument but this is not the "ideal" vacuum - it is the minimum possible in some conditions. The absolute vacuum is impossible - in nature or laboratory.
Can any quantity such as mass length or volume be measured exactly?
It is according to the measurement markings on the instrument. If there are many, it is more likely to be exact or accurate. Also it depends on if you started on the very center of the very first marking, and did not move the instrument while measuring. So, the answer is ... yes.
Explain the difference between absolute and relative power.?
In exercise physiology, the difference between absolute and relative expressions of anaerobic power is that absolute mean power is calculated using the constant rate of falling bodies while relative mean power is calculated using a person's body weight to be able to compare power produced by that individual to their own body weight.
What are you measuring when you measure air preasure?
The difference in pressure between absolute and gauge pressure.
What is an absolute instrument?
An absolute instrument is an instrument whose calibration can be determined by means of physical measurements.
What is the practical application of absolute values?
Measuring distances.
Which measure is not considered when measuring absolute magnitude?
distance from earth
What is the absolute way of measuring angles?
Using a protractor helps
What is kilopascal absolute?
A kilopascal is a thousand pascal - a unit of pressure. "Absolute" means the actual pressure - this is in contrast to measuring a pressure DIFFERENCE (usually, how much higher some pressure is, compared to atmospheric pressure).
What are two ways of recording or measuring absolute time?
With a stopwatch or a shotclock.
Ways of recording or measuring absolute time?
absolute time is time measured in definite periods such as minutes, days, and years

What is an absolute altimeter?
An absolute altimeter is an instrument which measures vertical distance to the surface below a certain reference point.
Any method of measuring the age of an event or an object in years?
absolute dating
What is the difference between absolute temperature scale and kelvin scale urgent I am convinced that there is a difference?
Absolute temperature IS MEASURED IN KELVIN.
