Taking DO readings

 During measurement, the probe can be:

 

Fully immersed in the solution

 

Partially immersed in the solution

Do not allow the probe’s membrane surface to touch

anything! The probe guard (the piece with holes fitted

over the end of the probe) protects the membrane; you

should leave this piece attached to the probe at all

times.

IMPORTANT:

 Since the DO probe consumes oxygen

from the sample, the sample must constantly flow past

the membrane to achieve more accurate readings. You

can use a stirrer to accomplish this.

To take measurements:

1. 

Rinse the probe well with deionized rinse water or

rinse solution.

2. 

Select the appropriate measurement mode. Press the

MODE key to toggle between modes:

 

% Saturation

 

mg/l (ppm) **

3. 

Dip the probe into the sample. Stir the probe gently to

homogenize the sample. Make sure that the sample is

continuously flowing past the membrane sensor.

4.  Note the reading on the display.  If the READY

indicator is switched on, it will appear when the

reading is stable.

5. 

Press the “LIGHT” key to activate the backlit LCD. This

helps you read measurements in dimly lit areas.

** To select between mg/l and ppm units, see Section 7.10.2 on page 42.

The ATC indicator should appear in the lower right hand corner of the display. If it does not,

this indicates an error.

saturation to mg/l
