CHOOSE YOUR SCALE IN 6 STEPS

1. For which sector do you need it?

• Education (from elementary school to university classrooms): education scales
• Laboratory, pharmaceutical: analytical balances; technical scales; moisture analyzers
• Industrial, freight transport: industrial scales; counting scales; floor scales
• Off-site weighing: portable scales
• Food (processing, preparation, reception): Food scales
• Retail: portable scales

2. How much precision / capacity do you need?

The numerous models of the scales are due to the different possible ranges between accuracy and capacity. In general, the more the scale is able to read small values, the more the cost will go up, so think carefully about the measurement values ​​you need. What will be the lightest and heaviest weight of your measurements?

Example: the NAVIGATOR NVT2200 can read at least 1 g, measure up to 2.2 kg and the cost is around 130 euros; the NAVIGATOR NV323, with the same functions and features, reads up to 0.001g and can measure up to 320g in weight, costing double the NAVIGATOR NVT2200.

3. Do you need special measurement functions?

Modern scales not only allow for basic weighing, but also other weighing options, to be used in various applications. It is therefore important to consider the functions of the scale and think about what types of weighing you will need.
For example, OHAUS cost-effective PR series can be used for Basic Weighing, Piece Counting and Percent Weighing ', while the sophisticated EXPLORER Series has a huge amount of applications: Weighing, Piece Counting, Percent Weighing, Check Weighing, Animal / Dynamic Weighing, Filling, Totalization / Statistics, Formulation, Differential Weighing, Density Determination, Peak Hold, Ingredient Costing, Pipette Adjustment, SQC, and Statistics.

4. What do you need to measure?

Another parameter that could be important, depending on the use, may be the size of the weighing pan. The bench scales for the laboratory can have a round or rectangular plate of medium sizes, while the industrial scales have a wider support surface, up to the load scales, floor, which square, can be up to 1,5 meter wide. So, what size will the samples you weigh be?

5. Do you work in particular environments?

In the industrial field, where you work with heavy and resistant tools, it will be advisable to equip yourself with a sturdy scale, with a metal structure and overload resistance, to avoid any damage to the scale. Examples are the portable scales / counting Ranger or the best-selling Defender, for larger items.
Or, if you work in humid environments, with very high standards of hygiene, you will need to equip yourself with scales with a high IP rating (read our post on food scales, to learn all about the IP rating of Ohaus scales). You will be able to equip yourself with a scale with the highest IP degree, IP69K, thanks to the Defender 6000 scale.
Also important, for some environments, is the protection from cutting tools, useful for those food sectors of portioning and preparation. In this case, the control panel is protected by an anti-cut membrane that will protect the display and buttons, ensuring safety and durability.

6. Other important functions

There are many particular functions to allow specific applications, below is an example list:
• Weighing from below: the scale is equipped with a hinge under the structure, where you can hang the object to be weighed
• Dynamic weighing: useful for example for veterinarians; even if the animal moves during the weighing, the balance will show an average value across all readings
• USB / RS-232 interfaces for data download and storage
• Blocking functionality; user password
• Plastic or metal structure

IL MONDO DELLE BILANCE PROFESSIONALI

Ora hai presente cosa ti serve, ma ancora non ti sono chiare le differenze tra le tipologie di bilance.
Qui di seguito ti spiegheremo nel dettaglio le diverse bilance che potrai trovare sul mercato e ti spiegheremo le differenze tra una e l'altra.

Bilance analitiche Pioneer:

Bilance di precisione ed analitiche EXPLORER:

Bilancia industriale:

Analizzatori di umidità:

Bilance per la didattica:

Bilance alimentari:

Analytical balance: An analytical balance is a very sensitive laboratory instrument, capable of measuring up to one thousandth of a milligram with a high degree of accuracy. Analytical balances have a weighing capacity in the range of 100-500 g and a readability of 0.1 mg - 0.001 mg.

Analytical balances should only be used by trained personnel and must have a draft shield or weighing chamber in the form of a transparent casing so that drafts and dust do not affect the operation of the analytical balances.

An analytical balance differs from a precision balance in terms of readability. Analytical balances have higher readability (0.0001g) than a precision balance (0.001g) and therefore tend to be more expensive.

The most common applications include:
• Sample preparation
• Formulation
• Interval weighing
• Routine testing of pipettes
• Differential weighing
• Density analysis

The most popular laboratory balances from Ohaus are the EXPLORER: large touchscreen display, numerous functions with display guides for the operator; RS232 and USB communication, remote control panel and precision up to 0.01mg.
However, you can get a quick overview of all the series on our Analytical Balances page.

Precision Balance: A precision balance has less readability than an analytical balance, but tends to have a greater capacity.

Thanks to their high accuracy and advanced technology, precision balances are used in laboratories to efficiently perform tasks such as weighing test materials, sample quantities, formulation, density determination, purity analysis, quality control testing and compliance test. Technical scales with higher capacities are not generally used in laboratories, but are used in other areas, such as construction sites.

Industrial or floor scale, for goods transport: these scales have all the necessary features, such as automatic zero, tare, piece counting (very useful for annual inventories) or weighing with limit values, depending on the model.
Industrial scales are tools used in a commercial or production chain. They have a large capacity, are very resistant, durable and meet the weighing needs both in dry environments or with the presence of water. The models vary from the bench scale to the platform and can operate via the mains or with rechargeable batteries, ensuring a very flexible use within your spaces.
The floor scales, or platform scales, are composed of a solid weighing plate in painted or stainless steel, non-slip almond plates and a large-digit LCD indicator. The scales have IP65 protection, are built with high quality materials and guarantee durability over time.
Which do you need?
• Over the counter we recommend the Defender series.
• Counting scales watch the Ranger series.
• For small shipments consider the Catapult 1000 model.
• For large shipments and goods control see floor scales.

Moisture Analyzers: Used to determine the moisture content of a sample. It consists of an infrared weighing and heating unit and performs moisture analysis using the 'loss on drying' (LOD) method, which is the most common method for moisture analysis; the sample is weighed before and after the removal of moisture. This is done by continuously recording the weight as the sample is heated and dried using a halogen lamp or other infrared radiator. When the sample no longer loses weight, the difference between the two weights is measured, which is used to calculate the moisture content. This is also known as the thermo-gravimetric principle.
Ohaus offers moisture analyzers with a simple digital display and basic and precise functions, such as MB23, or much more sophisticated models such as the MB120, with touchscreen, display graphics and a special smart guide to speed up configurations and daily use. .

Scales for teaching: any type of scale can be used in the didactic field, since it depends on the subject taught and the grade of the school. However, not having to be used for routine work, educational scales can do without some comfort features and therefore have a lower cost. Therefore, the Pioneers, the Navigators and the SKXs can be ideal for teaching.

Food Scales: Food scales are primarily legal for trade, NSF and HACCP certified. The common characteristics are: usable in very humid environments, up to 95%; have a clear and large display; easy to clean design; stable and adjustable support feet; portable, with comfortable grip; large support surface, in a
