What is Peak Hold on a Scale or Laboratory Balance & Why is it Important?

Описание: Today, it's time to learn about a relatively obscure feature that's actually found on quite a few scales. It's called peak hold and it's usually available on everything from floor scales to analytical balances. It's a versatile functionality that is not very well known.

But what does peak hold do?
Why is it useful on a weighing scale?
How should you use it?
Do you need it?

Let's find out the answers to these questions. So what is peak hold? The easiest way to define it, is when the peak hold function is activated, the scale records the highest reading detected by the scale or balance and holds the result on the display.

So you might be wondering, how is peak hold different from a regular hold function? The regular hold function just freezes the weight on the display when a button is pressed or the scale stabilizes. In this case, that means that the weight on the display would only show what first registered on the scale, paying no attention to the weight applied afterwards.

Peak hold will record the HIGHEST VALUE obtained rather than the first stable value or the average of multiple values. It can be useful when a lot of weight is applied very quickly and removed just as quickly. For example, if your scale measures  3 kg, 7 kg and 5 kg on it. The scale will hold and display the peak value. In this case, 7 kg.

So, you may be wondering, when is peak hold useful? proper engineering and manufacturing practices expect a certain amount of resistance from products that very depending on the material. For example, you don't want packaging to fall apart because of the weight in the box. Peak hold can be used to determine the material's tensile strength, which can help manufacturers determine if a material is suitable to contain and transport various objects, materials and chemicals.

In addition, consistency is important. Imagine buying a bag of candy only to find that some melt in your mouth and others hurt your teeth when you attempt to chew them. You probably would not buy that brand again. Quality testers need to ensure that tools that see heavy duty usage can always withstand daily usage without breaking randomly. A can with potentially volatile chemicals needs to be made of a material that can withstand a certain amount of pressure built up before it breaks, or people could get injured.

Many manufacturers use peak hold to test the amount of weight and pressure that can be supported by a part or piece to make sure components will not break from daily usage and stress on individual components. I hope this video helps you better understand peak hold and its importance.
