Measurement of the oxygen partial pressure, ðÎ2 ,
in liquid and gaseous biological media, their temperature and
atmospheric pressure in laboratory and field conditions. ðÎ2
is measured electrochemically using an amperometric Î2
electrode.
The instrument allows:
-
interactive control of instrument operation using a dual-line
alphanumeric LCD display and a user-friendly interface;
-
communications with the computer via an IR- or RS-232 Ñ interface;
-
using various Î2 electrodes with an operating
current of 1·10-11 to 1·10 -6 À , automatic
control of their characteristics, and automatic regeneration
of their working surface;
-
fast automatic one- and two-point calibration with any model
medium;
-
audio signaling of ðÎ2 readings settlement ;
-
automatic temperature compensation and correction for atmospheric
pressure variations;
-
saving up to 100 measurement data points, the last calibration
results, and parameter settings in the instrument memory at
the instrument switch-off for each of 10 O2 electrodes
used;
-
protection of structural elements against corrosive chemicals,
water and electrolytes;
