Laboratory Scales

Laboratory Scales

The laboratory scales (also known as a thousandth scale) that you'll find here at Digital Scales AZ are designed for use in a wide range of educational and research applications where high precision is required. Among our digital laboratory scales, you'll find a few high precision triple beam balances, which are better suited for some weighing applications.

Whether you intend to use your new scale for educational or researching purposes, the laboratory scales found on our site won't let you down. The triple beam balances we carry are great for use in the lab for measuring out liquids and powders and remain affordable for use in the classroom. While our selection of digital laboratory scales are available in ranging capacities and precisions, which provide solutions to countless laboratory weighing applications, due to their multitude of features and more than a dozen weighing modes. No matter which you choose, analog or digital, all of the laboratory scales found here will provide you with the most accurate and precise measurements of almost any object.

Before selecting your laboratory scale, there are a few terms that you should be familiar with. Starting with the most misunderstood, the difference between an objects mass and its weight. The mass of an object is always a constant unit that represents the matter of an object. The location where an object's mass is measured will not affect it. This unit of measurement will always remain the same and is usually measured in grams or kilograms. The weight of an object refers to the objects heaviness. This measurement uses the force of gravity on an object multiplied by the objects mass. Determining an objects weight will very depending on your weighing location. An extreme example, while the mass of an object doesn't change, if you were to weigh the object on earth and then on the moon, you would end up with two different weights.

The last couple of important terms are commonly confused and required to determine the quality of a scales results, which include accuracy, precision, linearity and readability. The accuracy of a scale is how close the provided measurement is to the actual weight of an object. The digital laboratory scales found here will always provide the highest accuracy; some are accurate down to one ten thousandth of a gram. The precision of a scale, also referred to as a scale's repeatability, has to do with the scales results being the same when repeatedly measuring objects of the same weight. The linearity of a laboratory scale is the tolerance range of the scale throughout its entire capacity range, not just at the calibration points. A good laboratory scale will have a very low linearity, which provides accurate weight results for any object within the scales capacity. Readability is the smallest unit of measurement that a scale can produce. This measurement is produced in a decimal point and can range anywhere from 0.1g to 0.0000001g. Understanding these few terms will hopefully make selecting a new laboratory scale a much easier task to accomplish.
