NEULOG OXYGEN SENSOR GUIDE

NeuLog oxygen sensor

NUL-205 Carolina # 369634

The oxygen sensor can be used for any science experiment or activity where oxygen

levels, dissolved or gaseous, are required. Some fields of study include Chemistry,

Physiology, Exercise Science, Biochemistry, Biology, Earth Science, Environmental

Science, etc.

Just a few of the thousands of possible experiments that can be done with the NUL-

205 sensor are: Monitoring of ecological systems, combustion reactions, oxygen

consumption rates, studying photosynthesis, testing chemical solutions, hydrogen

peroxide decomposition, and many more.

This sensor is practical for testing both in school laboratories and in the field and has

two modes of operation: open air mode to test gaseous oxygen concentration

(percentage of oxygen in the air), and dissolved oxygen mode for the testing of liquids

(mg/L and percentage dissolved oxygen in a liquid)

Units of measure this sensor measures are:

 % oxygen concentration in air: The concentration of gaseous oxygen

present in the sample.

 Mg/L: Total mass of dissolved oxygen per liter of a given liquid sample.

 % oxygen in water: The percentage of dissolved oxygen present out of an

entire liquid sample.

Sensor usage and storage:

Prior to use:

1. Remove the blue rubber cap from the NeuLog oxygen probe.

2. Unscrew the tip-end membrane cap of the probe, inside you will see a metal

electrode.

3. Add 1mL of the “DO Filling Solution” directly into the tip-end which was just

unscrewed.

4. Carefully reattach the tip-end of the probe by screwing it back into the

probe.

5. Do not replace the blue rubber cap until after testing.

Storage:

Short-term (less than 24 hours):

For short term storage, fill a beaker with enough distilled water to cover the membrane

cap of the oxygen probe. With the membrane cap still attached to the probe, place it

tip side down in the distilled water. This easy storage method is ideal for short term

storage, between trials or up to 24 hours.

Long-term (more than 24 hours):

1. Unscrew the membrane cap from the oxygen probe.

2. Discard the DO filling solution from the membrane cap.

3. Rinse the cap with distilled water and gently shake to air dry.

4. Rinse and dry the exposed metal electrode with distilled water; it can be

dried with lab wipes.

5. For storage purposes: Loosely reattach the membrane cap to the oxygen

probe.

Sensor calibration:

The NeuLog oxygen sensor does not need to be calibrated prior to each use because

the prior calibration settings are stored in the sensors software. We recommend

recalibrating prior to discrete data collection such as reading the specific oxygen

content of water samples.

Open air mode:

The oxygen sensor needs to be calibrated before use. Calibration of the probe

assumes a standard atmospheric oxygen concentration of 20.9% (assuming stable

levels in the Earth‟s atmosphere at sea level). The simplest calibration is to hold the

button on the oxygen sensor down for 3-4 seconds.
