Resistance to environmental factors, durability, ease of use, the time required for a measurement – these are the characteristics that differentiate between a mechanical and a digital subler and help you choose the right one for your projects.
Along with the hammer, roulette, pliers, leveler and a few other basic tools in any household that does not use a master for each nail to be beaten, the subler is an essential device, especially if you want to be able to accurately measure various objects . The most popular models available on the market at the moment are the mechanical ones and the digital options, among which it is good to choose informed, knowing as accurately as possible the advantages and disadvantages that each one offers you.
Digital screen versions are easier to read
Reading the measurement results is easier on a subler model with display, primarily because in most cases we are talking about screens generous enough to allow display with large numbers, easy to see even in low light or tired eyes. By comparison, mechanical options include two scales with small gradations, which can be difficult to observe for older users or when working in difficult, semi-dark spaces.
On the other hand, the classic format subler is based on your spirit of observation and ability to read correctly what you see, leaving room for human error. In this case we are talking about two readings, one on the main scale and another on the one with subdivisions, which depend both on the quality of your eyes and on the experience you have in the field.
For example, if you view the level at which the arm stopped on the scale from the side, you may not notice the correct position because of the angle, while the correct reading may reset as close as possible to a position perpendicular to the scale. Because this error can be made, out of haste or ignorance, twice until the result is obtained, digital versions are easier to use and more suitable for amateurs.
Mechanical versions do not require batteries
For digital models to work and display the result on the screen, they need a power supply, provided by batteries. Using such a device therefore always means extra care, involved in checking and replacing the batteries, even if most have a fairly long lifespan. In addition, if you know that you will not use it for a long time, it is good to remove the battery because it can be damaged, affecting the mechanism inside.
By comparison, a mechanical subler only needs a skilled hand and an experienced eye to work efficiently.
Digital options make a higher level of accuracy possible
The underlines are generally recognized because they can provide measurements up to divisions of 0.1 – 0.02mm, ideal for small objects and works in the wood or metal industry. For projects in the field of scientific research, mechanical engineering and other profiles where more precision is needed, digital models are more suitable. The technology makes it possible, in these versions, to achieve a level of accuracy of up to 0.001m (1 micrometer).
If you want a durable model, choose a classic one
The electronic components integrated in a digital version are sensitive to moisture, so they need protection from environmental factors. Their operation can be affected by mechanical shocks and the presence of electromagnetic fields and make it risky to use them in closed environments where there are flammable liquids or gases.
The mechanical options, on the other hand, are made entirely of carbon-enriched stainless steel, with a durable structure, resistant to falls, bumps and scratches, with low risk of corrosion – if properly maintained – insensitive to electromagnetic fields and moisture. It is the best option for those who work in difficult, tight, difficult to access spaces, where there is a risk that the tools will be frequently scratched or hit by obstacles.
Digital models include useful functions
One of the most useful functions offered by a digital subler is the fast setting, and on any position of the mobile arm on the scale, of the zero point. This option integrated in some models helps you to find very easily and simply differences in thickness, length, width or depth, without the need to make calculations.
Equally useful is the ability to lock the display to retain the latest measurement and the option to save multiple consecutive results for benchmarking or use over a period of time.
The classic version is cheaper
If you are not necessarily looking for the most advanced subler model and you only need a reliable, precise and durable tool that does not burden your budget, you will come out best with a classic version. The price varies in this case between 20 and 90 lei, depending on the brand, the quality of the material from which the product is made and the maximum measurement limit, which can vary between 450mm and 2000mm.
In comparison, a digital version involves an investment of at least 35 and up to 3000 lei, taking into account of course that the cheapest electronic devices are not always the best, so it would be advisable to focus on a mid-range model.
For fast conversions from centimeters to inches, choose a digital model
Although in the case of classic options you can perform the measurement on both scales, it is easier to do the automatic conversion with a digital option. Using a mechanical model you need to observe the results on two scales, an operation that takes more time than just pressing a button. For those who are forced to complete technical tables with product dimensions expressed in metric and imperial scale, the working time is therefore substantially reduced with an automatic version.
The classic type subler requires more experience
Both models involve basic knowledge essential for accurate results in the actual stage of measurement, to position the arms of the subler correctly. However, the classic options also require additional knowledge when it comes to using the four scales present (two in centimeters / two in inches) to correctly take the result.
