Medical Mass comparators
Mass comparators are devices designed for determining
the differences between masses of calibration weight (B)
and reference weight (A). Comparators are most often
used in measuring laboratories for calibration of weights
and masses. We offers comparators designed for
calibration of weights and masses class E1, E2, F1, F2, M1
according to OIML R111, ranging from 100g to 5000g with
readability from 0.01mg to 1mg. Main part of the
comparator is precise mechanical measuring system which
is separated from electronic circuits. Such solution
guarantees elimination of temp. influence (warming of
electronic elements) on the indications of comparator.
Comparator is equipped with big graphic backlit display
with user friendly menu in Polish and English language In
order to guarantee proper accuracy of measurements, a
half-automatic system of external calibration with
calibration weight has been applied. Comparator is
equipped with esthetic weighing chamber with glass
anti-draught protection. All elements of the weighing
chamber are manufactured from glass or metal which
minimizes the influence of electrostatic charges on
weighing result. Comparator is equipped with user friendly
menu. The software allows for composition of GLP
procedures as standard printout or as freely definable
non-standard printout. Each comparator is equipped with
RS 232, PS/2 output and possibility of connecting additional
display as standard.
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.
