CHARACTERISTICS OF THE METER

The  CO-505  dissolved  oxygen  meter  belongs  to  the  newest  generation  of
measuring devices which offer wide range of additional functions. The meter
ensures high accuracy and repeatability of readings. The electronic elements
of  the  newest  generation  used  in  the  meter  made  its  memory  independent
from  power  supply.  The  internal  clock  is    powered  from  battery  which  holds
its charge for many years. The meter is equipped with a custom, backlit LCD
display, which enables observing the measured function simultaneously with
the temperature value. Additional graphic symbols make working easier.
Main features of CO-505 are:

-

  high accuracy and stability of readings;

-

  automatic and manual temperature compensation;

-

  possibility  of  compensation  of  the  salinity  influence  on  the  oxygen

measurements

-

  measurement  and  automatic  compensation  of  the  atmospheric  pressure

influence on the dissolved oxygen concentration;

-

  possibility  of  introducing  the  time  of  calibration  validity  and  signalling  its

expiry;

-

  remembering  the  measurements  results  with  time,  date,  individually  or

taking series of measurements with set time interval;

-

  USB port;

-

  large LCD backlight display with brightness control;

-

  real clock and date.

WHAT IS THE METER DESIGNED FOR

Dissolved  oxygen  meter  CO-505  is  a  precise  and  easy-to-use  meter
designed  for  measurements  of  oxygen  dissolved  in  water  in  %  of  saturation
or mg/l and atmospheric pressure measurement in hPa. The meter may also
be used for accurate temperature measurement of solutions and air in °C.
The  meter  is  used  in  chemical,  pharmaceutical,  power  industries,  in  water
treatment 

stations, 

laboratories, 

agriculture, 

universities, 

scientific

laboratories etc.
The meter is prepared to work with galvanic oxygen sensor manufactured by
our  company.  It  may  cooperate  also  with  Pt-1000  temperature  probe  with
Chinch connector.
The  meter  may  collect  measurements  taken  as  single  or  series  of
measurements with set time interval.
The  built  in  USB  port  enables  sending  the  data  to  the  PC.  There  is  a
possibility  of  sending  current  results  of  measurements  or  the  stored  data
together with date and time thay have been collected.
In  case  of  necessity  to  collect  series  exceeding  the  memory  capacity  it  is
possible to use a special PC software offered by our company.
