Measuring Tools
Measuring instruments includes a vast amount of tools and instruments used for measuring. This would include micrometers (various types for various applications), scaled rules, durometers, spectrometers, tape measures, dumpy levels, spirit levels, combination sets, gauge blocks, vernier calipers, dial indicators, inside and outside calipers, etc.

What is the difference between a colorimeter and flame photometer?
A colorimeter is a scientific instrument that measures the intensity of light passing through a pure sample. In biology, colorimeters are used to monitor the growth of cultures. As the culture grows, the growing medium becomes more cloudy and absorbs more light.
Which graduated cylinder is more precise a 25 mL or 100 mL?
As far as sig figs are concerned, the graduated cylinder will yield a measurement that is both more precise and accurate than is possible using an Erlenmeyer (precision and accuracy mean different things in science talk). Erlenmeyer flasks aren't really intended to be used for measurement of volume, as the width of the flask at the point of the markings introduces lots of error as you try and eyeball the level of fluid within it. The narrow column of a graduated cylinder will allow you to judge volume far more accurately since a difference in the height of fluid in one of these will result in a lower overall difference in volume when compared to the Erlenmeyer.
Keep in mind though, that just because a graduated cylinder contains a certain volume doesn't mean that it will deliver that entire volume to another container, since some of the liquid inevitably clings to the sides. This isn't a problem is you are simply trying to measure volume, but if you are trying to pour an exact volume into another container you need to use another method to do so. In this case your best bet is to pipette.
When thermometer is laid ouside the sun does it measure suns temperature or air temperature?
If a thermometer is laid out in direct sunlight, it will not measure the temperature of the air surrounding it. It will measure the temperature of the heat directly reaching it.
What would you use to measure something smaller than a meter?
A centimetre or a millimetre for everyday objects. Or micrometre for things still smaller - eg thickness of a hair.
Or if you are talking abount things on a very, very tiny scale, a nanometre or picometre. And that's not the end of metric prefices!
A gear tooth vernier is a precision measuring instrument used to measure the dimensions of gear teeth, specifically their thickness, spacing, and profile. It typically features a vernier scale that allows for accurate readings and adjustments, ensuring precise measurements of gear components. This tool is essential in gear manufacturing and quality control, helping to ensure that gears meet specified tolerances and performance standards.
What would you use to measure the mass of a pear?
To measure the mass of a pear, you would typically use a digital kitchen scale or a balance scale. Place the pear on the scale, ensuring it is stable and not touching any other objects. The scale will provide a direct reading of the pear's mass in grams or ounces, allowing for an accurate measurement.
What is the meaning of the mark in every 16 inch in a measuring tape?
mujhe nhi pta..inch tape waalon ne chutiya kaat rakha hai.......maul lo roj lo....jai gyan devta....jai badhra kali...
What shows how much space is taken up by liquid?
A measuring cup is one such device.
A dipstick is also used to measure the space taken up by a liquid, although the answer is rarely given in standard units.
What would you use to measure volume of an irregular object?
I would place it in a container full of liquid after measuring the liquid.
I would measure the amount of liquid displaced by the object.
That amount is equal to the volume of the irregular object if it is fully submerged in the liquid.
What is meant by internal indicator?
Sometimes one of the reactants in a titration act as an indicator; this is an internal indicator. An example is the volumetric technique of permanganometry.
Metric calipers are measuring tools used to accurately determine the dimensions of an object in metric units. They typically consist of two jaws (inner and outer) for measuring inside and outside dimensions, as well as a depth gauge for measuring depths. Metric calipers are commonly used in various industries such as engineering, manufacturing, and construction for precise measurements.
How is measuring in centimeters like measuring in inches?
They both measure the length of a material. They just have different units and conversions.
What type and source of error when or while using vernier caliper?
The Vernier caliper is an extremely precise measuring instrument
Error is almost impossible The error that we must always look out for is the zero error and parralex error.
451000000 micrometers is how many meters?
There are 1000000 micrometers in a meter
Answer is 451
+++
They have a name of their own: "micron", but the standard ISO symbol is the abbreviation for micro-metre formed by prefixing the letter 'm' with the Greek letter lower-case 'mu'. Thus:
µm
(I had to copy that from 'Word' because Answers seems not to have a symbol set. You may also find mu by the key combination ALT+0181.)
A micrometer is a measuring device.
What is two grains in the apothecary system?
In the apothecary system, two grains is a unit of weight commonly used to measure small quantities of medications and substances. One grain is approximately 0.065 grams, so two grains would be about 0.13 grams. The apothecary system, which has largely been replaced by the metric system, uses grains as a traditional measure, particularly in pharmacology. It is still sometimes encountered in prescriptions and compounding practices.
How you can modify the wind vane to detect the speed of wind?
You fit it with 3 cups that revolve with the wind from any direction and record the velocity through a cable to a gauge. This is called an "anemometer"
What is the tool for measuring mass?
well, it depends on how "massive" of the mass, if it is very big, you can use a loadometer or weighbridge, if it is not big enough, a normal balance will do it.
