The NANO.AK-4/500 automatic nano mass comparator enables determining mass deviations of weights with the minimum possible operator participation. The comparator allows to compare weights of mass ranging between 0.05 mg to 500 mg.
Excellent Measurement Repeatability
NANO.AK-4/500 automatic nano mass comparator, due to the elimination of the human factor, temperature changes and air drafts, guarantees excellent measurement repeatability when compared to manual mass comparator.
Design and Functionality
An element that controls mass comparator operation is a digital management module, which is placed inside comparator’s chamber along with an automatic mass standard feeder. Mass comparator is operated by means of indicator connected to the comparator controller. Control elements are not mechanically integrated with the construction thanks to what the influence of ambient conditions on mass comparator chamber is significantly reduced.
Dedicated Software
Specially designed RMCS computer software enables comprehensive realisation of calibration procedures in laboratory. The system manages the whole calibration process, starting from the moment the order is placed, through proced

Repeatability is expressed as a standard deviation determined for 6 ABBA cycles. Standard deviation is experimentally determined under ambient conditions for calibration of E1 class mass standards specified in OIML R111 (Table C.1.) document.
