We depend on weighing scales every day. We weigh our fruit and vegetables at the local supermarket. We weigh our bodies after waking up. And we weigh our luggage before hopping on a flight. Depending on the job you’re in, weighing scales might be as essential to your operations as computers and stationery. But with lots of different options available, which weighing scales are best for you and your business?
A&D Weighing offers a wide range of weighing scales for all applications. Whether you are looking for a commercial, personal or laboratory scale, you can most likely find what you need at A&D Weighing.
What’s the difference between a weighing scale and weighing balance?
Before we explore the different options, it’s helpful to understand the difference between scales and balances.
Scales generally measure weight relative to the force of gravity. Some use springs and measure how much they compress to determine the weight of an object. While modern weighing scales typically rely on electricity and strain gauge load cells. Placing an object on these types of scales causes them to compress, creating a change in electrical resistance that’s measured in the strain gauge and converted into weight. Scales are often used in settings that don’t need the acute precision of a weighing balance, like gyms, restaurants, grocery stores, factories and homes.
Weighing balances use more complex technology to deliver more accurate results. They’re built with a force restoration mechanism that opposes the force of the object you place on the balance. Weight is calculated by measuring the amount of restoration force needed to return the balance to equilibrium (a net force of zero). Weighing balances’ high level of precision makes them a vital tool in labs, research centres, chemists, hospitals, universities and other settings where minor inaccuracies can have major implications.
Which weighing scales should I buy?
There are few key points to consider when buying weighing scales.
- First, you need to determine your budget. Understanding your budget gives you a clearer idea of the products available in your price range, and helps you to prioritise certain features over others.
- Next, what types of objects will you be measuring and how much accuracy do you require? If you’re working in pharmaceuticals, for example, you’ll need a more accurate device than if you’re measuring food and beverages. The nature of your work may also require a certain level of readability on the scale – this can range from 0.1g to 0.0000001g.
- Finally, you need to choose a scale with a weight capacity that’s suitable for what you’re weighing. Industrial materials and pallets will demand a much greater capacity than powders and chemicals.
Now that you’ve had a think about your budget and the features you need, let’s look at the different types of scales offered by A&D Weighing.
Analytical balances are highly sensitive, making them perfect for labs where precise readings are required. They’re typically built with a force restoration mechanism and are designed to detect even the slightest incremental change in weight. If you’re working with small samples and require a medium to high level of readability, an analytical balance is an effective and reliable option.
Most analytical balances have a counting feature, which is helpful when counting pills and other other small objects. Other key features to look out for are data reporting and tracking capabilities, automatic calibration and ionisers that remove static from the sample.
Compact bench scales
Compact scales are great for food preparation and weighing smaller objects like fruit, coffee beans, coins, jewellery and parcels. While most compact scales have a capacity under 50kg, some models can cope with weights up to 150kg. Their ease of use and space-saving size makes them a staple in homes, grocery stores and factories.
Compact scales aren’t built for high readability and precision. But if you’re looking for a durable and affordable set of scales that are perfect for weighing everyday objects, compact scales make for a great investment.
Industrial scales are built to cope with the most challenging loads and have a higher capacity than other types of scales. If you work in manufacturing, packaging warehouses or loading docks that frequently measure heavy and oversized items, a quality set of industrial scales are essential.
Some industrial scales have a built-in printer that creates labels on the spot. This is a great feature for shipping businesses that pack and send high volumes of products.
Similar to analytical balances, laboratory balances are high precision weighing instruments designed to measure the minute. The applications for laboratory balances vary from quality control and pharmaceutical testing, to scientific research and development. Typically, they offer a readability of up to 0.0001g, making them suitable for the very smallest samples in the sub-milligram range.
Health Scale and Personal BMI scales
Health scales are specially designed to weigh bodies. Most of us have a set of health scales in our bathroom, while doctor’s offices, hospitals and clinics rely on health scales to accurately weigh patients. Health scales are also commonly used in gyms, schools and sporting clubs.
There are a variety of different health scales on the market that cater for different needs. If you’re an athlete, personal trainer or simply want greater control over your health and weight, you’ll benefit from a set of precision scales for personal use with additional features like a BMI calculator and weight tracking. There are also walk-on bariatric scales for patients that need extra stability, and scales featuring an incline ramp for wheelchair access.
Moisture analysers measure the moisture content in a sample. Their diverse applications make them a crucial tool across a variety of different industries. They’re commonly used in the food industry to control excess moisture in food that can lead to bacteria growth. If you’re involved in selling food by weight, a moisture analyser will ensure your customers aren’t paying for excess water. Conversely, too little water and your food may lose flavour and become dry.
Labs also use moisture analysers to measure the amount of water in a wide spectrum of solids, liquids and gases like plastic, crude oil, sewage and dielectric gases.
One of the biggest benefits of moisture analysers is their efficiency. They significantly reduce the time it takes to analyse moisture compared with traditional and manual laboratory moisture testing methods.
Like industrial scales, platform scales prioritise capacity over precision, making them suited to heavy duty weighing environments. In particular, they’re designed for bulky items like shipping crates, pallets and heavy luggage.
Premium platform scales can greatly improve your productivity with features like quick stabilisation and computer connectivity, as well as counting, percent and accumulation modes.
Postal, retail and counting scales
If you’re in the business of selling, you’ll likely have a set of scales in your workplace.
Postal scales are made specifically for precise letter and parcel weighing. They’re perfect for calculating shipping weights and delivery charges, and clearly display changes in price as mass is added or removed. Make sure to choose postal scales that are approved by Australia Post LPOs.
Retail scales are the scales you’ll see staff use when you place an order at your local deli. They accurately measure food, beverages and other small objects, and show key information like weight, price per unit and total cost on a display. To boost your efficiency even more, you can connect retail scales with cash registers and point of sales software.
Counting scales can save you time and money by turning tedious manual processes into quick and easy tasks. For instance, a hardware store can save hours of effort by using a counting scale to instantly find out how many screws there are in a pack (where every piece weighs the same). Like other retail scales, you can pair counting scales with printing equipment to create product labels in a flash.
