How To Choose The Best MG Scale

How do you choose the right milligram scale for your needs?  You will need to consider the following points and that should help you with making that decision and guide you through some terminology that you are not use to that comes with the product description and technical jargon on these products.

What will you be measuring with the scales?

First of all you need to consider what are you primarily using the scales for, will it always be for powdered chemicals or solid items such as a diamond or do you need it to measure a range of things which range from liquid to maybe larger items such as food. 

This consideration helps because these types of scales come with different types of pans or trays to put the item on, so a cheaper model may well come with a large tray which would be excessive if you only ever measure 5g or 10g, you would be better off with the slightly more expensive set of scales which comes with a small pan; also higher sided than a tray therefore offering more protection if you are likely to be measuring powders.

How big or small a weight will you be measuring?

Next, are the quantities you are weighing never going to exceed 20g or do you need a higher measure, say up to 50g? 

As you might expect, scales with a smaller range are going to give you more precise accuracy and be smaller in size so if you are likely to need to carry them around with you say for measuring gems, they will fit easily into a pocket and often come with a suitable carrying case.

You may require your milligram scales to supplement your standard kitchen scales for food preparation especially if you are dieting, so require smaller measurements of food than your normal scales can accurately measure for you so that usually means opting for a larger set of scales, that can weigh up to 500g and give a broader and flat weighing area, possibly with trays so you can balance and manage the food item conveniently.

Other functions or properties of the scales

Once you have defined the style and weight range of scales that you require most of them have similar properties and functions. 

These types of scales use Triple A batteries to power them and are often supplied when you buy them, also the majority of them will come with calibration weights for future re-calibration as certainly the more expensive scales come ready calibrated but do double-check whether they need to be calibrated before use (instructions for doing this will be in the user manual).  

Another feature with these scales is that they can measure in different unit weights i.e. gram (g) ounces (oz), carats (ct), pennyweight (dwt), grain (gn/gr), troy weight (ozt) which is very helpful to have if you happen to need to switch between measuring medicinal powders and gold.  It is usually just a case of selecting which mode you require.

You will often see mention of a TARE function with these scales too.  Tare in relation to weighing items means the net weight can be given minus the tray or cup that you have needed to place on the scale to contain the item you are weighing, again a good feature to look for.

How Digital Kitchen Scale Helps You to Diet

Soon summer will be here and you will want to sport your skinny self in a hot new swimsuit.  You figure that the best way to be able to do this is loose at least ten pounds, and then you can enjoy the holidays. Your reasoning is that if you loose the ten pounds and then gain it back, you have not really gained any weight at all. If this is your line of thinking, then you need to purchase digital kitchen scales to help measure the portions.

There are many styles and a wide range of prices. All of these MG scales do the same job of accurately measuring your food, but some of them even have a listing of over 900 different foods you can type in and see all the nutritional value. There are flat scales, square ones, and even one that is small enough to put in a desk drawer at work or home.

Some of them come with a removable bowl, and others let you put the food right on the scale. They will measure in ounces, grams, and pounds. Some of them even subtract the weight of a container that you put on the scale to measure your food into, and give you the actual weight of the food. Most of them use batteries but there are electrical ones. They also have large LCD to make the numbers easy to read. They also have a removable plate for easy washing and sanitizing.

These scales are not just to help keep you on the right track in portion weighing, but they can also help you when you are fixing that special dish and you want to get the ingredients right. You can also use the milligram scales as a postal scale.

These kitchen scales work in the same way as the larger ones do in your local deli. They have a strain gauge, which evenly distributes the weight of whatever you put on top of the scale. The smaller scales will weight up to one pound and is used mainly for measuring. You can get scales that will weigh items to eleven pounds.

How To Use Milligram Scale Perfectly

Always make sure the scales are placed on a steady and flat surface that isn’t going to get knocked or react to vibrations from loud music or machinery.  

If they have been stored in an area that is cold (they feel cold to the touch) allow them to reach an ambient temperature (room temperature) before you start measuring, metal can contract in the cold, so it just allows the machinery to adjust and settle ensuring the optimum accuracy.

Be aware of not placing the scales in an area where there is a draft or likelihood of a draft occurring. Place them away from any windows or doors, electric fan heaters or air conditioning units etc., you don’t want to suddenly find your carefully measured powder has literally gone puff and is disbursed all over you and the room!  

To ensure that you are always getting the most accurate measurement from your scales you are likely to need to check the calibration of the scales on a regular basis which is why calibration weights are supplied with the device. 

Yes, your naked eye may be telling you that the quantity you are weighing looks more than say the usual 5 grams you measure out, so if that is the case, double-check it by using the calibration weights and following the re-calibration guide.  

However, don’t leave it to when that is the case, schedule in regular checks and of course if you are carrying the scales out and about with you, it is imperative that you check the calibration before a weighing session; these are very sensitive and delicate tools, so any knocks or major movement can disrupt their accuracy.

Keep the scales, clean and dust free at all times, the stainless-steel fabric of these devices together with the lids or covers are provided to assist you with this as any residue left on the pan or device is going to give you a false reading on the new substance when you are working with these very small margins of measurement.

Final Note

So, I hope you have found this guide useful in helping you to pinpoint which of the right milligram scale is going to work for you.  

It doesn’t matter whether you are measuring out chemicals for drug or firearm use, seeing how many carats are in that beautiful ruby stone that has been passed down through the family, or the number of chocolates that come in that sharing bag of candies.  

There is something very satisfying about knowing exactly and precisely what something weighs so happy measuring.
