Calibration weights are used to weigh things. They come in masses such as a 100g or 500 weight. They are used to exactly and accurately measure objects. They are placed on a scale and are then used to weigh the object.
When pumping, the weights should be rotated slowly to decrease cylinder wall friction.
Typically it is Cast Iron* that is used to make weights.

Temperature calibration is a term used to describe an evolution in measurement activities when the affects of temperature must be accounted for, or even nullified, when making measurements. Temperature affects a great many measurements, and its affects must be accounted for if accuracy in any measurements is to be had. It could also be applied to the chemistry of materials where an action or a reaction requires mixtures whose ingredients are blended in proportions that are temperature dependent. The quality and the productivity of countless industries depend on accuracy in so many areas of production or service. Calibration is a huge business within industry because of the demand for accuracy in any instruments that are used to measure anything. Many tens, or even hundreds of millions of dollars are spent annually on calibration activities. And thermal (or temperature) calibration is a chunk of that. Why not take a quick look at what calibration is all about? A link is provided to the calibration article posted by our friends at Wikipedia, where knowledge is free.

Weights which have been carefully measured and crafted for the specific purpose of calibrating scales should be used in scale calibration. These weights need to be of a known weight in order to adjust the scale.

Calibration standards are used to record the accuracy of certain calibrations that are performed. The accuracy allows the user to find out how good the calibration was.
If one is looking for calibration weights for scales one can try the local hardware store. One can also check some online websites like Ben Meadows or Forestry-Suppliers.
You will need weights between increments of a gram (to 2 decimal places) and up to 100 grams. This is if you want to calibrate for the metric system.

Internal calibration is a process used inside a system to make fine adjustments. It is commonly used in equipment and vehicles to maintain accuracy.
With each objective, the calibration must be recalibrated because the calibration only applies to its calabrated objective.
Calibration equipment is equipment used to test the accuracy of other equipment, and make sure it is as accurate as it needs to be. If used on a set of bathroom scales, it might involve a set of weights that are known to weigh 20Kg, 30Kg, 40Kg, and so on. (These weights might be as much as 0.2Kg under or over weight, for example.) These would then be put on the scales, to make sure the scales gave a reading that was 20Kg, 30Kg 40Kg. For bath room-scales the 20Kg weight might produce a reading from 19 to 21Kg, which is plus or minus 5%, IE an error of 5%, with the "calibration weights" 1.25% accurate. For bathroom scales this would be "OK" Depending on what is being calibrated there would be a degree of error that would be allowed. For scales in a hospital measuring drugs a 5% error (perfectly OK on the scales in your bathroom) could result in a fatal overdose.
Calibration gases are used to ensure that gas detectors are operating properly when working in confined spaces. They are commonly used in underground utilities or natural gas refineries.
Erbium has a strong absorption in uv and visible range, It is used in HPlc calibration for the wavelength accuracy verification of the PDA detector.
