Spring scales – Buying guide & Comparison
If you’re short on time and you just want to find the best spring scale, this short paragraph should help you get exactly the model you need. According to our findings/research, the Ohaus 8008-PN is the best because of its reliable use as a weighing instrument for general applications, action-reaction demonstrations and force experiments. Boasting premium quality and craftsmanship, this spring and hook scale is equipped with a metal face plate that is very easy to read, complemented by its metal spring, hook and pointer that provide lasting use. The plastic housing makes it easy to clean and ensures resistance against rust. Designed with an 11.25 pound/50 newtons capacity, this spring scale has a metal face that shows measurements in 0.25 pound or 1 newton increments to make it easy to add or subtract exact values from what is being weighed to minimize the guesswork during the task. If the Ohaus 8008-PN is unavailable, your second option should be the Ajax Scientific ME505-0250.
Known for its simplicity, robustness and pocket friendliness, a spring scale works by measuring the weight of an object through the opposition of the force of gravity moving against the force of an extended spring. A spring hanging scale is typically a small instrument that, in simple words, measures the magnitude of forces which is, in this specific case, weight. How can you distinguish a good quality product in the best spring scale reviews from one that has lower ratings?
Readability and suitable capacity for your application
For a spring scale to live up to its primary purpose of measuring weight, it should be easy to read the result of the weigh in. The numbers should be easy to read especially at eye level, since you’ll be working with the scale hanging by its attachment hook and the user in a standing position. The numbers should be in small enough increments to allow the addition or removal of any items from the object being weighed while minimizing the guesswork you have to do to facilitate the process. Small hash marks are helpful for calculating the total weight. The divisions or lines between the numbers or hash marks should be evenly spaced.
How much weight the scale can measure denotes its range. This element is especially important if you intend to use the instrument for measuring heavy objects. While mechanical hanging scales can measure up to 100 kilograms, the smaller models measure up to 250 grams to 5 kilograms. Other models measure up to 5 newtons only, while some measure to 11 pounds or so. Remember to choose a model that has more than enough capacity to handle the objects you intend to weigh.
Quality materials and craftsmanship
Premium scale manufacturers use metal components combined with durable plastic material in their products. A metal face plate provides lasting use while ensuring resistance to corrosion, with the spring housed in tough metal housing that is not easily breakable. Some models are equipped with a strong polystyrene case with a flat anodized metal scale that allows you to read in both grams and newtons.
Ideally, the back of the scale should be longer than the length of the spring itself when it is stretched out fully, and this will also include the size of the hook and the plastic housing. The best spring scales carry a design that is simple so there are fewer components that could get damaged, break down or stop working. The spring should be thick and durable, capable of stretching to its full length and going back to its original tightly coiled state after every measuring procedure. This component should withstand multiple and repeated use by having a high elastic limit. The ring stand clamp should be durable as well. Some models have chrome-plated rings and hooks.
Dependably accurate weighing performance
Although spring scales are not expected to be as accurate as other types of scales, it still pays to know that you can measure items using this type of device with more-or-less the same accuracy as you would using a standard weighing scale. The scale should be easily adjusted to start precisely at zero, and the readings obtained should not be enormously off. Some models even come with a zero adjuster to ensure consistent accuracy. A vintage spring scale with a dial face should be robust and compact with a large dial housed in a strong metal case to hold the spring components in a solid configuration.
