Radwag AK-4.1000.5Y Automatic Mass Comparators

OVERVIEW

Maximum capacity [Max]: 1.02kg
Readability [d]: 0.005mg

Application:
Automatic mass comparator AK-4/1000 series is intended to automatic determination of weights mass deviations with operator’s activity limited to the minimum. The comparator enables determining deviations of three tested weights in a single cycle. AK-4/1000 is designed to compare weights from 100 g to 1 kg. The instrument is commonly applicable in mass measuring laboratories, and particularly in certification units for weights classes E and F.

Design and functionality:
The supervising part of the mass comparator is a digital module which cooperates with a controller of instrument’s mechanical components. The digital module and the automatic loader are located in mass comparator’s weighing chamber. The instrument is operated by means of digital display which is plugged to mass comparator’s controller. The supervising elements are not integrated with mass comparator’s mechanical parts, thus enabling separation of instrument’s weighing chamber from ambient conditions influence.

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.
