Mass comparator AKM-2 series featuring automatic mass loader enables automatic determination of mass deviations of a single weight in a single cycle. The system of automatic mass comparator is commonly applicable in mass measuring laboratories, and particularly in certification units for weights classes E, F and M
The supervising part of a mass comparator is a digital module which cooperates with a controller of instrument’s mechanical components. The automatic mass loader features a basis with self-centring fields, a robot and a steel body. The digital module and the robot are located in mass comparator’s weighing chamber. The loading robot is controlled by the computer’s controller. The instrument is operated by means of digital display which is plugged to mass comparator’s controller.
Lengthwise shift of the loading robot with weights is carried out automatically using solenoid actuators. Additional software functions enable loading and taking off the weights, data processing and storing, and data export to instrument’s memory.
- Effective and Excellent Measurement The AKM-2 automatic mass comparator enables determining mass deviations of weights with the minimum possible operator participation. The comparator allows to compare weights of class E1 and lower of mass ranging between 500 g and 50 kg. The device is available in 2–position version for 1 reference weight and 1 test weight.
- Maximum Comfort of Operation To ensure maximum comfort of operation, the mass comparator is equipped with automatic sliding feeder facilitating loading of large-mass weights.
- Excellent Measurement Repeatability The AKM-2 automatic 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 Specially designed weighing pan enables precise and accurate comparison of the smallest weights. The knob for changing the weighing range allows to compare vast range of loads while maintaining the same resolution. Stable construction of the table with heavy granite stone and robust rubber shock absorbers minimizes the influence of vibrations.
- 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 procedure performance, to the moment of issuing the calibration certificate
