The Adam Equipment DCT 201 Dune compact portable balance has a capacity of 200 g and an accuracy of 0.1 g (also called readability), and offers a two-second settling time that allows for increased productivity. 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. This balance has an automatic external calibration system that ensures repeatable measurements, and an overload protection indicator that prevents damage to the weighing cell and balance by warning the user if too-heavy samples are mistakenly used. The large, splash-proof digital display is easy to read, and the simple three-button keypad provides quick taring and unit selection. The plastic housing and weighing pan are lightweight and durable enough to withstand use in the field and tough lab environments. Warrantied by manufacturer for one year.

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.
