XA 4Y.M and XA 4Y.M.A microbalances




XA 4Y.M – The latest series of microbalances equipped with spacious weighing chamber and featuring range of innovative solutions and functionalities.

The highest measurements accuracy
XA 4Y.M microbalance features the highest measurements accuracy, excellent repeatability and is compliant with USP requirements (Chapter 41 and 1251). .

Intuitive operation and large touch screen
5.7″ colour touch screen enables intuitive operation and easy access to numerous applications and functions of the weighing instrument.

Touch-free operation
To enable touch-free operation of the balance, any function or application can be assigned to both programmable proximity sensors.

Combined weighing pan shields
The new weighing pan shield design reduces disturbances caused by air drafts, and provides easy access to the weighing pan making dispensing of the samples comfortable.

Vibrations sensor
Continuous monitoring of vibrations informs the operator about vibrations level during operation. The solution improves reliability of carried out measurements, this is due to elimination of an accidental error caused by ground vibrations.

New door opening automatics (only for XA 4Y.M.A)
The innovative weighing chamber system for door opening and closing guarantees smooth and quiet door movement, and eliminates vibrations that may disturb the measurement. The solution also enables to define door opening angle.

Defined profiles
Four predefined profiles enable automatic balance parameters customization.

  • FAST – the measurement is carried out within a very short period of time, result stabilization takes up to 2 s,
  • FASTDOSING – the balance quickly reacts to mass changes, especially useful for dosing or adding more mass to the dispensed portion,
  • PRECISION – balance settings providing the minimum standard deviation sd ? 1,5 ?g,
  • USER – profile customized by the operator.
