The Adam Equipment MDW-250L digital physician scale measures the weight of a subject up to 250kg with an accuracy of 100g (also called readability), and the attached measuring rod can measure the height of a subject in 0.5-centimeter increments up to 210 centimeters for a comprehensive physical assessment. The indicator has a large backlit liquid crystal display that provides clear readings in bright or dim lighting. The metal platform measures 275 x 375mm (W x D), and has a top tread plate with a nonslip surface for safety. The metal base creates a durable foundation for use in gyms and hospitals, and provides stability for increased accuracy. The scale operates using AC power or the built-in rechargeable battery, offering full mobility for up to five hours. The auto off function can be enabled to power off the scale automatically after periods of inactivity to conserve power. The scale has an automatic external calibration system that ensures repeatable measurements, and an overload protection indicator prevents damage to the weighing cell by warning the user if the capacity is mistakenly exceeded.
The scale tares over the full range and weighs in kilograms and pounds. The hold function can be programmed to freeze weight measurements on the display for a preset time limit, for recording weight measurements. The built-in RS-232 port connects to a computer or printer for recording data, and printing can be synchronized with the scale's hold function to print automatically when the measurement is stable.

Scales and balances are measuring instruments used to determine the mass of an object. 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 (0.0001g 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. The company, which was founded in the United Kingdom in 1972 and has an office in Danbury, CT, meets International Organization for Standardization (ISO) 9001:2008 standards.
