MXA series of balances has been designed to meet high requirements for measuring small masses with high readability
(d = 1 µg). They are equipped with graphic display with extended user menu. In order to guarantee proper accuracy of measurements, has been applied automatic system of calibration.

Microbalance consists of two components. One of them contains electronic modules, and the other precise mechanical measuring system. Such solution guarantees elimination of temperature changes influencing the indication of the micro balance.
Microbalances series MXA are offered with three capacities 5 g, 11 g and 21 g (with readability 1 µg). Balances are equipped with esthetic, cylindrical shaped weighing chamber with small glass draught shield. Microbalance is offered also with big glass draught shield for protection of the instrument against influence of external conditions. All elements of the weighing chamber are manufactured from glass or metal which minimalizes the influence of electrostatic charges on weighing result. Microbalance is equipped with user friendly menu. User has access to multiple functions and measuring units which allow for specification of working requirements. Microbalance software allows for composition of GLP procedures as standard printout or as freely definable non-standard printout. Balance series MXA is equipped with RS 232, PS/2 output and possibility of connecting additional display as standard.

Microbalance is in high degree influenced by external conditions like temperature, breeze and vibrations. For the purpose of proper operation conditions, it is necessary to use the microbalance in a room with very precise temperature control (laminar air-conditioning) and place of usage should be free from any vibrations (anti-vibration table).

Microbalances do not undergo Legal Metrological Control (verification) - norm PN-EN 45501 specify only weighing equipment class I with "e" bigger or equaling 1 mg. when estimating the errors of indications, one should bear in mind, that in accordance to international norms included in R111 verification is not performed below 1 mg, and the tolerance of the weights of the highest class E1 is respectively: for 10 g ± 0.02 mg, and for 20 g ± 0.025 mg. for this purpose , the main criteria for evaluation of microbalances is repeatability and linearity.
