XA 4Y F Analytical balances

Category Laboratory Balances
Manufacturer Radwag
Country of manufacture Poland

The Most Precise Control over Filters Absorption Capabilities: Professional weighing pan featuring an additional draft-shield made of glass enables accurate measurement of large-size filters for excellent quality and accuracy of determining filters absorption capabilities during differential mass measurement

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.

16 GB RAM – more data management possibilities
16 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.
