Medical Mass Comparators
Mass comparators are devices specially designer for
determining the differences between the weight of
checked standard mass (B) & weight of reference standard
mass (A). Mass comparators are most often applicable in
measuring laboratories, where calibration of weights and
standard masses is performed. We includes in its offer mass
comparators for calibration of weights & standard masses
class M1 according to OIML R111, ranging from 500kg,
1000kg and 2000kg with readability 5g, 10g or 20g.
Mass comparator Series BWY is equipped with big, backlit,
graphic display, and user menu operating in Polish and
English. In order to assure highest measuring accuracy,
mass comparator has semiautomatic adjusting system with
Comparator 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 comparator in a room with very precise temperature
control (laminar air-conditioning) and place of usage should be free from any vibrations.
Comparators do not undergo Legal Metrological Control. Main criterion if evaluation is repeatability. The software is
equipped with application for estimating average deviation by two methods: ABA or ABBA, for maximally 20
repetitions. After running the procedure, the software generates the report with results.
external standard mass. Weighing platform is manufactured in mild steel technology. It is resistant against scratching
and easy to keep clean. Mass comparator is equipped with user friendly menu allowing for generation of GLP
procedures as a standard printout or freely definable user printout. Mass comparator is equipped with RS 232 output,
2×USB & Ethernet.
