The Adam Equipment CQT 251 Core portable conventional, or precision, balance has a capacity of 250 g and an accuracy of 0.1 g (also called readability), and offers a two-second settling time that allows for increased productivity. The stainless steel, 120 mm diameter pan is corrosion resistant, and can be easily removed from the base for quick clean-up. The balance can be operated using AC power or six 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. Overload protection prevents damage to the load cell if too-heavy samples are mistakenly used. The below-balance weighing hook suspends bulky items beneath the balance for weighing.
The balance has a liquid crystal display with a character height of 18 mm that can be backlit for better readability, and it weighs in nine different units. The automatic external calibration function ensures repeatable measurements. A built-in security slot for locks and cables protects the balance from unauthorized use or theft. The balance can be stacked and stored on top of other Core or Highland balances that have a 120 mm diameter pan, with or without the draft shield, to save space. Warrantied by the 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.
Adam Equipment manufactures balances, scales, and related accessories for laboratory, educational, industrial, retail, and medical applications.
