The XA 4Y.A Series Analytical Balance features a new 5.7” color touch screen display – a modern interface for balance operation and measurement presentation. It enables customized parameter selection along with user profiles.

A distinguishing feature of the XA 4Y.A is the automatic side glass doors with infrared proximity sensors located on the terminal. The XA 4Y Series also includes an internal automatic adjustment system using a built-in mass standard. The balance level is monitored by LevelSENSING system, a RADWAG patented solution including an electronic level. The 4Y Series has standard online monitoring of ambient conditions using either internal sensors or the external THB 3 series module.

The XA 4Y Series includes a large weighing chamber protected by an anti-draft shield from ambient conditions – this also ensures cleanness of the chamber interior. The weighing chamber design enables fast and easy disassembling of its glass parts thus ensuring clean weighing area and sterility.

The interactive mode of the XA 4Y Series guarantees speed and reliability for formulations based on data acquired from balance databases. Differential weighing mode facilitates incremental counting processes. Extended databases enable a user to keep records of all acquired measurements; additionally, data export and printing is available.

A newly implemented pipette calibration mode supported by a dedicated adapter forms an ergonomic tool for calibrating and checking of piston pipettes by means of a gravimetric measuring method.

Due to standardized and customizable printout formats, a user can design and document practically any process in accordance with the requirements of GLP/GMP methods. The balance also features an independent mass control mode compatible with automatic feeder PA-02/H Series.

• 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.

• Under-Pan Weighing: The solution enables weighing with use of a stand, which is advisable for loads of non-standard shapes and dimensions and those that generate magnetic field.
• Pipettes Calibration: Function verifying correctness of piston pipettes functioning, the verification is performed via gravimetric measurement of the excreted liquid. Pipettes calibration may be either a stand-alone module or it may be operated.
• Automatic Sliding Door: Automatic side panes opened via touch-free IR sensors.
• Density Determination: Liquid or solid body density function uses the Archimedes principle and it requires a special kit to be applied. The kit when used, replaces a weighing pan. For solids mass of the sample must be determined first in the air, next in the liquid of specified density. For liquids the so called sinker, density of which has been determined, must be measured first in the air, next in the tested liquid. The density determination process is disturbed by air bubbles which may stick either to the measured sample or the sinker. In case of laboratory equipment very light solids may be measured. For industry, solid bodies density may be determined by means of under-pan weighing. Tested load of significant size may be measured this way.
