Professional scales for laboratories, industry, food and teaching

OHAUS

Always the point of reference in the scale market.

With over 100 years of experience serving the weighing industry, no company has the knowledge to build quality products like OHAUS.

Known around the world, the New Jersey-born company has been manufacturing safe, accurate and reliable balances, analytical instruments and laboratory equipment since Gustav and Karl Ohaus founded the company in 1907.

THE WORLD OF PROFESSIONAL SCALES

If you have already read our post 'Find the scale you need in 6 steps!' then you have already made up your mind of the characteristics that your future electronic scale must have. Now, you would like to better understand the types of scales in circulation, to identify exactly the series and model that's right for you.
Below we will explain in detail the differen. We will explain the differences between one and the other and you will be able to find links to the various Ohaus series that Jointlab offers you.

Pioneer analytical balances.

EXPLORER precision and analytical balances.

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.

OHAUS Scout STX portable scale.

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.

Defender industrial scale.

Precision balance.

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.

Balances for moisture analysis MB.

Moisture analyzer.

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 removal of moisture. This is done by continuously recording the weight while 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 humidity analyzers with a simple digital display and basic and precise functions, such as the MB23, or much more sophisticated models such as the MB120, with touchscreen, graphic displays 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 scale, the Navigators scale and the SKX scale can be ideal for teaching.

Food scales Valor.

Food scales.

First and foremost, food scales are legal for trade, NSF and HACCP certified. The common characteristics are: usable in very humid environments, up to 95%; they have a clear and large display; easy to clean design; stable and adjustable support feet; portable, with comfortable handle; large support surface, in stainless steel; cut-resistant panel and low cost. In which places are they suitable? In many: professional kitchens, bakers, catering companies, pizzerias, pastry shops, butchers, fishmongers, food industry, supermarkets etc.

The main Ohaus series is called VALOR and is divided into 5 other series, from the cheaper VALOR 1000 to the more sophisticated VALOR 7000.
