XA 4Y.A.I Analytical Balances




Integrated Antistatic Ionizer

The antistatic ionizer, with which XA 4Y.A.I microbalance is equipped, neutralizes electric charges inside the weighing chamber upon placing the sample in it. The ionizer neutralizes uncompensated electric charge accumulated on weighed object. The lower relative humidity and a reading unit of the balance, the more evident influence of static electricity. The influence of static electricity gives greater repeatability error, often also greater error of indication.
Measurement errors, due to the harmful effects of electrostatics, often reach the value of thousands of reading units and more. The problem concerns non-conductive samples, e.g. glass flasks, paper filters, plastics, etc.

Antistatic ionizer implemented in XA 4Y balances, due to the application of modern technology, compensates both cations and anions. The ionizer activates when the microbalance door opens, and deactivates when the door is closed. It is possible to control ionizer operation using weighing instrument panel. The operation is signalled by blue LED diode which emits light when the ionizer is on.

Innovative 2-point adjustment system
Brand new adjustment system guarantees the highest measurement accuracy. It minimizes linearity errors simultaneously providing reliable indications for the whole weighing range.

Faster measurement with the new CPU
4Y balances feature Dual Core 2 x 1 GHz processor which delivers noticeable performance improvements including faster operation and shorter stabilization time retaining high repeatability values.

8 GB RAM ? more data management possibilities
8 GB RAM offers possibility of recording data in a form of complex reports. Time and statistic data diagrams on series of weighments are another useful option.

The best possible repeatability and USP regulations conformity
The best weighing accuracy and repeatability ? with sd ? 1d combined with USP regulations conformity (Section 41 and 1251) make 4Y balances a new standard for mass measurement quality.

Ergonomics and safety
Wireless communication between balance terminal and a weighing unit make it possible to comfortably operate 4Y series balances in laminar air flow cabinets and fume cupboards.

Remote control operation
Wireless Connection module offers wireless transfer of data recorded by 4Y balance to any portable device powered by iOS or Android systems using special applications intended for data management.

Data safety
Every single 4Y balance features ALIBI memory designed to provide protection and automatic recording of your measurements. Options such as data preview, copying and archiving are also
available to users.
