Ohaus Pioneer Analytical Balance

The Ohaus Pioneer analytical balance with draft shield has a high-contrast, backlit LCD screen for viewing results in dim lighting. This balance provides precise weighing results, and performs parts counting and percent weighing tasks. This balance has an external calibration system, and an indicator on the front panel provides quick confirmation that the balance is level prior to use. Three selectable settings adjust the sensitivity of the balance to compensate for excessive vibration, airflow, and other environmental disturbances. The rear RS-232 port is positioned for easy connection to a printer or computer, and enables work in compliance with GLP (Good Laboratory Practices) traceability requirements. The integral below-balance hook suspends samples beneath the balance for measuring specific gravity and density.

A built-in security slot for locks and cables protects the balance from unauthorized use or theft. Adjustable feet provide level measurements and stability, so the balance will not tip under eccentric loads. The ABS plastic and metal housing protects the internal weighing cell from environmental influences and impact. The stainless steel weighing pan resists corrosion from spills of most sample materials. The draft shield, designed with all-glass panels, including three sliding doors, can be disassembled without using tools or moving the balance, and all components, including the balance housing can be quickly wiped clean. A replaceable in-use cover protects the display and keypad against damage from spills. 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.
