BA-T series
With a 5-inch wide color touch screen, the BA-T series brings maximum operability, enhanced functionality and a broader range of solutions. All models come standard with an external ionizer (static eliminator).

Effortless microgram weighing thanks to the following features

Automatic opening/closing of the breeze break doors

The side doors of the breeze break can be opened/closed using the non-contact IR sensors on the display unit (or optional foot switches) for smooth, efficient access to the weighing chamber which improves repeatability by eliminating human contact with chamber doors. Utilizing a new and patent pending actuator technology, the BA draft shield operates quieter and smoother than conventional systems.
• Draft Shield Flexible door positioning ensures maximum visibility to the weighing chamber.
• Inner Draft Shield for 0.001 mg models For an extra level of stability and protection.
• Easy Leveling Feet Effortless leveling due to the front level indicator, 2 adjustable feet (opposed to 4) and on-screen leveling assist.
• Automatic Doors Set the opening distance to full, half, or to a preferred distance

Touchscreen and user navigation

The resistive touchscreen enables intuitive operation while making it easy to enter numbers, change settings, etc. even while wearing thick gloves
• IR sensors Programmable and touchless IR sensors enhance stability and engage functions such as auto doors, print and zero
• Display Unit 5" TFT, LCD, resistive color touch screen with 2 x IR sensors , multi language display and four quick access keys for easier navigation

Innovative design makes cleaning the balance simple and effortless

• Easily removable glass panes Each glass pane of the draft shield can be easily removed for thorough cleaning/disinfection thanks to the unique easy clip system.
• No bottom grooves for sliding doors The doors suspend from the top of the housing instead of resting on grooves so that contaminants do not accumulate during use.
• Detachable draft shield The draft shield unit itself can be easily removed from the weighing unit by pulling out the two side fasteners. This allows for fast, simple cleaning as well as replacement in case of damage.
• On-screen leveling assist The touch screen provides a visual instruction on which leveling foot to rotate in which direction(s) depending on the position of the air bubble on the level indicator.
• AD-Just Automatic self sensitivity (calibration) adjustment The balance can be set to adjust automatically using its internal weight according to the set execution condition (i.e. temperature change, preset time or interval) when there is nothing on the weighing pan to ensure consistent measurement results. An indicator blinks to give notice before the adjustment starts.
• Internal repeatability test The balance can test and calculate repeatability (standard deviation) using its internal weight to quickly assess the performance under a given environment.

Impact shock detection (ISD) The ISD function detects impacts applied to the weighing sensor and indicates their severity in .ve levels from 0 to 4. Level 3 and Level 4 are also accompanied by a beep alert. ISD helps to reduce impact loads in future weighing, and thereby avoid measurement errors as well as potential damage to the weighing sensor and to diagnose potential negative environmental influences.
Impact loads of Level 3 and Level 4 are saved in the Impact Shock Detection History log. If there is a problem with the balance, the log can be used to check how the balance was used.

Smart routine check (SRC) The SRC function displays the balance handling level, in three levels based on the number and strength of impacts loads received by the weighing sensor (available as part of the daily check function described later). This allows you to assess and manage risk related to poor handling, and helps improve balance operating skills.
The balance recommends you to perform performance (periodic) check if it is judged to have been handled badly.

External ionizer for instant static removal With the provided ionizer, you can easily ensure that your sample is free from destabilizing static electricity. The fanless ionizer will not disturb the sample and ensures maximum stability.
The ionizer is powered by the balance which minimizes clutter and eliminates the need for a second receptacle.

• Antistatic treatment Both the interior and exterior glass panes of the draft shield are coated to help block static electricity
• 316 stainless steel load pan
• Die cast aluminum housing with anti-static ABS cover

Daily/periodic balance check The balance can perform a daily or periodic diagnostic check to confirm leveling, environmental conditions and accuracy. The intuitive interface guides users through the checking process, eliminating the need for a manual or specific training.

• Daily Check Items Level check (image shown), external condition check, weigihng pan check and accuracy check.
• Periodic Checks Eccentricity measurement (image shown), calibration test, sensitivity (calibration) adjustment, repeatability measurement and sensitivity test.

Diagnostic results can be printed or saved to USB for further analysis and traceability

Minimum weight setting and alert
You can set the minimum weight for the balance either by direct key input or performing a repeatability test, from which the balance automatically calculates*2 the minimum weight.
Repeatability measurement for minimum weight setting
The minimum weight is determined from the standard deviation of 10 repeated weighing results. The detailed results data can be output for your records.

Minimum weight alert
Minimum weight requirement (optional)
To ensure that the measured sample amount meets the minimum weight requirement, the balance can display an alert until the sample amount reaches the minimum weight. You can also choose to set the balance to disable the output of weighing data less than than the minimum weight.

Advanced user access control
The BA provides complete administrative control by offering 4 separate authorization levels. This ensures that each user only has access to whats required to perform their daily tasks.
The administrator can register users as lab managers, supervisors or operators. Lab managers and supervisors are registered with usernames and passwords while operators do not require a password to login. Up to 100 users can be registered.*3

Change audit log
The balance can display/save to a USB .ash drive*4 log-in/log-out history, operation (changes to settings) history, sensitivity (calibration) adjustment history, and impact shock detection (ISD) history with date, time, username and other necessary information for later reference.

GLP/GMP/GCP/ISO compliant output
Data necessary to comply with GLP/GMP/GCP/ISO can be added to sensitivity (calibration) adjustment reports, calibration test reports, and series of weighing results

Specialized application functions

• Formulation mode - The formulation mode enables quick, accurate weighing of multiple samples to mix according to a set recipe, allowing for setting the target value (g) and tolerance (%) for each sample. Up to 150 samples and 300 recipes can be registered for easy creation or selection/change of recipes.
• Weighing screen in formulation mode - On-screen instructions guide you to weigh each designated sample to the target range. The [SAVE] key to proceed to the next step becomes active only when the weight is in the target range, which prevents errors (either Below Tolerance or Above Tolerance is displayed while it is outside the target range).

HPLC mode
The HPLC mode is dedicated to preparing buffer solutions for high-performance liquid chromatography (HPLC). In addition to weight (g), it enables you to set the target of each sample in terms of molar concentration (mol/L or mmol/L). From the molecular weight of the sample and the volume of the buffer solution to be made, the balance automatically converts between molar concentration and weight, to eliminate the potential for human error.

Recipe edit screen in HPLC mode
You can simply have the balance calculate/ display the weights to be measured even if the sample quantities are speci.ed by molar concentration.

Currently, 13 samples that are commonly used to make buffer solutions are already registered with their molecular weight information by A&D by default. In addition up to 30 samples (and 300 recipes as with the formulation mode) can be registered.

Both formulation and HPLC mode results show the measured quantity and tare value for each sample, which can be printed out or saved to a USB .ash drive in CSV format.
