1 DESCRIPTION AND OPERATION
1.1 Purpose
1.1.1 Product name and designation
MAPK-302E dissolved oxygen analyzer
TU 4215-022-39232169-2008
.
1.1.2 The analyzer has been designed to measure the dissolved oxygen
concentration and water temperature.
1.1.3 The analyzer may be used to measure the mass concentration of wa-
ter-dissolved oxygen and temperature of surface, waste and drinking water, and
may be employed by fish farms; chemical, biotechnological and food industries;
educational institutions and ecology branches.
1.1.4 The type of analyzer:
amperometric;
with external poling voltage;
with one sensitive element;
with a digital LCD display;
with automatic temperature compensation;
with dip sensor;
with automatic calibration when the sensor is placed in the oxygen envi-
ronment (air) at temperatures varying b15 °С and +35 °С;
with automatic adjustment for atmospheric pressure during calibration.
