The Ohaus SP401 Scout Pro portable precision electronic balance has a capacity of 400 g and an accuracy of 0.1 g (also called readability). The high-contrast, six-digit LCD shows results in four weighing units and multiple application modes. The balance can be operated using AC power or four AA batteries, for full mobility in the field and when a power supply is hard to find, and the auto off function can be enabled to power off the balance automatically to conserve power. The balance has an external calibration system to ensure accurate measurements, and includes a 200 g calibration weight. An integrated shipping lock protects the weighing cell during transportation or storage, and overload protection prevents damage to the load cell if too-heavy samples are mistakenly used.

The balance weighs in four common weighing units: gram, ounce, troy ounce, and pennyweight, and the application modes include parts counting, percentage weighing, totalization, and display hold for oversized samples. An integrated below-balance weighing hook suspends bulky items beneath the balance for weighing. The ABS plastic housing, along with a sealed front panel and molded spill ring, protect the balance from environmental influences and spills, and the stainless steel platform can be removed for easy cleaning. A built-in security slot for locks and cables protects the balance from unauthorized use or theft. The balance is manufactured to ISO 9001:2000 standards, and warrantied by manufacturer for two years.

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.
