AAA analytical high precision balance

Balance Information

AAA Series precision analytical balances are your answer to the conscious effort to get the most balance for your money.  These balances feature internal motorized calibration, robust die cast aluminum housing with stainless steel weighing pan and removable weighing chamber floor makes clean-ups a breeze.  The generously proportioned weighing chamber and weighing pan, together with the practical, but uncomplicated operating features make it a pleasure to use the AAA Analytical Balance.  Three sliding glass doors allows for easy access from the right, left or top.

balanceCombining high resolution with highly competitive prices the AAA Series outshines all other analytical balances with internal motorized calibration on the market today.  The simple five-button keypad is designed for ease of use and provides fast stabilization times with the consistent and dependable weighing results you need for your precision weighing requirements.  Attention to fine details like the "TARE" key (the one you'll use most) is highlighted in yellow for quick recognition and use emphasizes Adam Equipment's experience in designing fine precision weighing instruments.

Compensate for minor temperature variations by simply pressing the "CAL" button on the display and the AAA Analytical Balance's built-in calibration weight allows the user to seamlessly set the balance for maximum accuracy quickly and simply.  The AAA can be calibrated externally, but requires accessing a menu structure via the keypad and entering a special service code parameter along with the purchase of optional external calibration masses.  For those customers who require yearly certification to a known external calibration mass to meet their ISO requirements we recommend the AEA series over the AAA since its external calibration is much easier - by just pressing the "CAL" keypad and placing the external mass on the weighing pan.

The new ABC software (Automatic Balance Calibration) can sense the change in ambient temperature outside predetermined limits and automatically perform the calibration for you.  The GLP compliant software package enables print out of full calibration details when connected with the Adam Thermal printer.

State-of-the-art software and force restoration weighing technology ensure consistent and reliable levels of performance.  The cantilever mounted weighing pan effectively isolates the sensitive force restoration mechanism from the contents of the weighing chamber, helping to ensure continuous reliable performance.

Seven 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 sent 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.

simple 5 button dispaly and large LCD for easy viewingAll Adam Analytical balances feature an Auto Zero function to automatically rezero the balance which can be enabled or disengaged.  Auto zeroing will reset the zero of the balance if the zero point should drift from the initial zero condition.  The auto zero function is typically enabled to ensure a stable zero condition.  However, some weighing operations may be affected by this function.  Examples are filling applications where the materials flow very slowly from a buret or liquids that change their state from liquid to gas while being weighed.  If the user tares the balance with the sample on the pan and is looking for the amount of material that might evaporate - having the autozero function set may not show the true weight loss.  Disengaging the Auto Zero function will eliminate this problem and can be changed simply by accessing the "F" key from the display pad.

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 AAA.

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-L 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.
