State-of-the-art software and force restoration weighing technology ensure consistent and reliable levels of performance. 

density determination kitSeven selectable weighing modes (grams, milligrams, carats, grains, mommes, ounces, pennyweight) and bi-directional RS-232 interface (selectable 300, 600, 1200, 2400, 4800 & 9600 baud) are standard.  Data can be set via the RS-232 to the Adam Thermal Printer or PC by simply pressing the "PRINT" key on the indicator keypad.  The balance can also be configured to stream the data out for continuous output for weight loss versus time analysis.  The date & time printing function can be enabled to meet GLP/GMP requirements using the the Adam Thermal Printer.

balanceAll Adam Analytical Balances and 3-decimal-place toploading balances can be purchased with an optional density determination kit.  Now you can easily determine the density / specific gravity of samples when you purchase this $425 accessory.  Adam balances take you step by step through the weighing process, calculating the density and displaying the results on the LCD in g/cm3 using their advanced internal software. The density determination kit includes all of the parts required for weighing the sample in air and in a liquid.  A glass sinker is supplied for density calculations of liquids.

For working in an unstable environment digital filters and suppression of the last digit on the display (in grams mode only i.e.: 20.0151 > 20.015) facilitate optimal response time and speeds up weighing operations.  A big, clear LCD display and sealed key-pad with a positive feel "click" make it easy to operate the AFA .  The AFA Series also features internal motorized calibration enabling you to calibrated the balance by pressing the keypad.

Adam Equipment is based in the UK and is a company with more than 30 years experience in the production and sales of electronic weighing equipment and during this time has built up a reputation for quality, reliability and value.  The AAA-LE balances are only a small part of our extensive range of laboratory balances enabling you to select just the right balance for the job in terms of capacity, readability, features and price.  See the full line of Adam Equipment products here.
