The Ohaus Primer elementary balance is a mechanical beam balance with a capacity of 2000 g and an accuracy of 1 g (also called readability) that measures in grams and has a manual tare adjustment across the entire weighing range. Made of ABS plastic, this balance is durable enough to be used in primary and intermediate classroom settings. The two plastic weighing buckets, which are marked to enable measurements to 500 mL, can hold liquid or solid samples, and are easy to remove for pouring samples, cleaning, and storing. There are dual pointers on either side of the balance base that enable students to view readings from both sides of it. This balance includes a guide with 16 educational activities to help teachers demonstrate measuring concepts using common liquids and solids. It is manufactured to ISO 9001:2008 standards, and when used according to manufacturer’s recommendations, this product is covered by a one-year warranty.

Balances are measuring instruments used to determine the mass of an object, while scales are used to measure the weight of an object. The measurement results from balances are generally considered to be more precise compared to results from scales. Mechanical balances are the simplest type of balance, and use a lever and slide to indicate the measurement. Conventional balances are commonly used in offices, the jewelry industry, and in kitchens, and display results digitally, but are less precise than analytical balances. Analytical balances measure to a high degree of precision and accuracy (0.0001 g or better), and display results digitally. These balances have a cover with doors to prevent dust and airflow from affecting the measurement. Moisture balances analyze moisture content in a material sample, using infrared or halogen heat sources to dry the sample and then calculate the moisture content from the before- and after-drying weight, and display results digitally, on the balance, or transfer the information for display on a computer.
Ohaus manufactures scales and balances for laboratory, educational, retail, food, and jewelry applications. The company, which was founded in 1914, is headquartered in Parsippany, NJ.
