The Adam Equipment CBK 16a portable bench scale has a capacity of 8,000g and an accuracy of 0.2g (also called readability), and a stainless steel weighing pan that resists corrosion and is easy to clean. The scale can be operated using AC power or the built-in rechargeable battery, for up to 90 hours, offering full mobility in the field and when a power supply is hard to find. 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, and overload protection prevents damage to the weighing cell if too-heavy samples are mistakenly used. The automatic data accumulation option continuously and reliably stores data internally in the scale’s memory, while the integrated RS-232 port connects to a printer or PC for either manual or automatic external recording of weighing and calibration data. The scale weighs in five different units and has an LCD with backlight that clearly displays readings, a real time clock (RTC), and a capacity tracker for visual reference to prevent the scale from being overloaded. The scale performs weighing, check-weighing, percent-weighing, and parts-counting tasks. Red, yellow, and green LED lights notify the user during check-weighing mode if the load is under, over, or within the pre-set weight limit, while security passcodes can be employed to safeguard against the alteration of check-weighing limits. The ABS plastic housing is built to withstand tough field and lab environments. Adjustable nonslip front and rear feet provide level measurements and stability, so the scale will not tip under eccentric loads. The included below-scale weighing hook suspends bulky items beneath the scale for weighing.

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. What’s in the Box?
