PS-100 and PS-105: USPS Postal Scales Review
Standing in line at the post office waiting to get your mail weighed takes a lot of time, and time is money. That’s why the best thing to do is to invest into a postal scale, preferably a digital one. For smaller packages up to 10 pounds, some of the best scales are USPS PS-100 and PS-105.
The PS-100 Desk Top Postal scale offers measuring range from 0.1 oz to 10 pounds in 0.1 oz steps. The readout can display weight of the item in ounces, pounds and ounces and grams. Switching between various displays is easy by push of a button.
The hold feature of the scale enables you to weigh very large objects that cover the display. Just press the HOLD button after you put the package on the scale and it settles. After the button is pressed, the value on the display will remain frozen so you can read it after the removal of the package. Flip-up easel on the top enables easier weighing of loose objects such as tubes.
The display is actually a 1.3 inches big LCD screen that is very easy to read. Automatic shut-off function on the scale will save power, which is important when running on battery power. This digital scale can be powered by an included AC adapter, or by three AA batteries.
There’s not much difference between PS-105 and PS-100. The difference is that this scale can weigh objects in range 0-5 pounds. It also doesn’t have AC power source, it can only be powered by 3 AA batteries.
Both scales are purposed for weighing light items only. Exceeding recommended weight values can cause damage to the scale’s weighing mechanism.
Technology of Digital Scales
In this day and age, weight measuring is usually done electronically, with the help of digital scales. The range of weights that they can measure is wide, going from very light (as low as 0.05lbs) to heavy objects. The technology that makes digital scales possible is the load cell. It can measure the pressure applied to it, and the electronics in digital scale can transform that value into the weight of a measured object. This information about the measured weight is carried by a digital signal.
Digital scales are available on the market from different brands, modes, shapes and sizes. They usually come with accessories such as AC adaptors, trays and calibration weights. Usually a simple user manual comes in the package. With different models come various prices and build qualitites.
Many areas of scale usage will benefit from having a digital instead of mechanical scale. Digital scales are more accurate,efficient and reliable than their mechanical counterparts. Some of them can even fit in a pocket, as their size can be really small. Is much harder to make a mistake in measurement when using a digital scale. Many electronic scales offer a way to connect them to an accounting system or a computer. Many different applications are avaliable because of this, for example automatic postage calculation, label creation and printing. All these extra features can make a digital scale much more expensive than mechanical one.
Digital display is also one of the important features of a digital scale. Important characteristics that determine the readability of the display are size, LCD matrix quality, backlight type and digit size.
High precision in measurements is an important characteristic of a high quality digital scale. Overloaded scales should not break easily. Other parameters that influence the quality of a scale are weight capacity, precision and accuracy.
Digital scales can be used in industry, warehouses, laboratories, medical fields and homes. Scales can have many purposes, so they can be specialized for single or multiple functions, such as bathroom scale, kitchen scale, postage scale, floor scale.
